Top ReviewsMIO Fuse vs Fitbit Charge HR
by J. K. (4 out of 5 stars)
January 25, 2015
I have been looking for a comparative review of these two products. Since I couldn't find one, I decided to do it myself. I put each through a meticulous week of training and will display my findings as simply as possible. I have a lot of information that I am condensing so if you have any further questions, please ask.
For my test, I did a range of different exercises including HIIT, SMIT, medium intensity steady state cardio, jogging, and weight training. Though neither device can truly give a comprehensive measurement for weight training, my lifting style fluctuates my heart rate enough to quantify a decent calorie burn, so I included it.
Also, please note that I tried various adjustments including alternate arms, wrist spacing and tightness. I literally ran the gambit, and in some cases, it made a major difference. I have pretty large wrists/forearms, so regardless of position, both devices had little trouble finding a baseline pulse. I used the Samsung Galaxy S5 as my control since it was rated as top notch against EKG machines.
So, let's begin with the meat of these new devices: heart rate tracking.
Fitbit Charge HR does not do well with spikes, on either arm. In fact, the display would often display "- -" and not find a suitable rate for at least 30 seconds. When doing HIIT/SMIIT, 30 seconds can be an eternity in documenting measurements. When it did come through, it was still 10-15 beats slower than the Mio and the S5. I had little issue with the Mio Fuse. It wasn't perfect, but I usually had a solid reading within 3-5 seconds, and I would say 90% of the time, it was in line with the S5.
During anything steady state, the Charge HR and the Mio Fuse kept consistent readings with both the Precor 100i and the S5, but when the Charge HR was on the non-dominant hand, it was typically 5-10 beats behind. When I went jogging, both devices kept the pace, but just for kicks, I let my heart rate drop and pushed out a full on sprint. Mio caught up within 5 seconds, Charge HR was blank for at least 25 seconds. Reiterating that the Charge HR doesn't like spikes.
One other point to note is that during weight lifting, the Charge HR had 2,000 more documented steps than the Mio Fuse. The manual stated that may happen with activities involving rapid arm movement, but just noting I didn't have that issue with the Mio Fuse.
I can't pinpoint why the Charge HR is inconsistent on my non-dominant hand. If it uses capillary enlargement, I can only guess it's because they are more evident in my dominant hand. Either way, their inequality should be noted.
The interface is where Fitbit excels. As a longtime fan of my Flex, I love the improvements they have added. The heart rate chart and the time zone measurements are great. But it is far less enjoyable when the information (heart rate) is inaccurate. The Mio Go app is truly bare bones. It has very basic tracking and gives you basic stats on your daily workout and overall activity. I also had a few sync fails when connecting to the app and lost my workouts, which was really frustrating. It still shows up in my daily caloric burn, but when you want specifics, this is very disappointing. There is also no PC counterpart, so it's all mobile. Mio has stated the app will be growing based on feedback. I hope so, because the device deserves a better interface.
I, personally, do not care for all the bells and whistles of each, so I didn't spend much time here, but I can offer a few distinct differences. The Charge HR has 24 hour heart rate tracking, while the Mio Fuse has to be activated in workout mode. Since the Mio Fuse was much more accurate in my tests, I would rather have the accuracy during my workouts than be able to see my heart rate during my daily routines, so this is a wash. The Charge HR is sleeker, and the "action" button is harder to accidentally trigger. With the Mio Fuse, it is pressure based touch screen, so when using the TRX, I have to check after sets to make sure I don't stop my timer on accident. The "lock" feature needs to be able to be turned on for workout mode. The Mio Fuse is waterproof for 30 feet, while the Charge HR is not recommended for showering or swimming. Both devices caused some irritation after long periods of usage, but it usually disappeared within a few minutes of removing the devices. I really wanted to focus on what these devices were boasting about...strapless HR tracking.
So, upon these tests, I must bid adieu to my Fitbit family for now. I can see the Mio Go app getting better before the Charge HR becomes more accurate. I have read that the Surge has better accuracy, but I am not looking for anything more than a solid hr activity tracker and the extras of the Surge are not worth the premium in my opinion.
For standard daily activity, both devices are great for comprehensive readouts and steady state tracking, but if you are a fitness enthusiast who constantly pushes your limits and capabilities, I recommend the Mio Fuse.
Good Heart Rate Monitor, Comfortable Fit, Quirky Controls, Good For Swimming, Lousy Mio App
by BobbyG/YTWB (4 out of 5 stars)
March 14, 2015
You need to know a few things about this wearable monitor before you buy it. First: it's very comfortable and made out of flexible silicone. It feels soft even when you wear it snug as suggested. Easy on, easy off. I wear it above my watch and have also worn it upside down with the clasp on top of my forearm, it's comfortable both ways. Once it's on it doesn't move and after it has acquired HR it doesn't lose it. I've had it on all night and didn't even know it was there.
You better be a tinkerer with patience, it's not exactly a put-it-on-and-forget-it type gadget. (update: after the a day of two of messing with it it gets easier) After it's strapped on you must initialize it in order to get HR. Easy to do and it finds HR quickly. Then you must launch the app and although the app is customizable, it takes some doing. From within the app you can select the gadget's display to be on continuously or through touch only. The next item almost kills this thing for me, it's the Lock Screen option. Once you lock the screen you can't mess with it, right? Not so. While only using the basic functions without HR, you can lock the screen and next time you tap it only show the last used function. It takes a while for that to work after you set it in the app. It's EXTREMELY frustrating to get that to work properly. BUT.... even if you get it to work in Daily Mode, as soon as you initialize HR, the screen unlocks. Huge problem because the touch points are so sensitive that just drops of water can change the screen function. Worse, it's too easy to pause a workout without realizing it. And when you pause the workout you're not recording. Which brings me to the next issue. The Mio Go app only displays actual HR as a number while connected, nothing else until after the workout, when you have stopped the timer and let the monitor sync with the app. Only then do you get to see some details of your workout. A half-assed HR graph at best. You cannot zoom in and there isn't much other detail about the workout. Crappy app. Luckily, unlike the Fitbit Charge HR, the Mio Fuse will work with a whole bunch of other third party apps. Wahoo is very good but even better is Sportstracker. Fantastic app with a dashboard that shows everything such as current HR%, average HR for the workout and highest achieved on one screen, perfect for a stationary workout. It also has an nice detailed HR graph and voice notifications if you set it up. It tells you what you're doing.
The MIO works via Bluetooth (BLE) or ANT+. Both apps above work better with ANT+, BLE has a tendency to interrupt more often. I only use the Mio app to set the screen options, nothing else. The third party apps are superior and do NOT require the workout function to be active, only HR needs be initialized. To better understand how this works, the third party apps record on your smartphone in real time whereas the Mio Fuse records the workout internally when the workout mode is entered and afterwards sends it to the Mio Go app. You must stop the workout before it can sync with the Mio app.
Overall it's a nice monitor if you understand its limitations. No fancy OLED screen, just old fashioned but effective dot matrix readout. Great for actual workouts using third party apps. If you want to count steps etc you can wear it all day but it really shines during workout using other apps, especially Sportstracker.
It doesn't have a sleep analysis function like Fitbit Charge HR but after you've seen how that works I don't think it's particularly useful anyway.
The Lockscreen function is confusing and only works in Basic Daytime Mode. My biggest complaint is that Lock Screen unlocks as soon as HR is intialized.
I personally don't care about steps/stairs/calories/distance so cannot review those functions.
Battery life seems sufficient, you can mess with it all day and it doesn't run out of juice.
Good HR monitor
Good battery life
Great free third party apps available
Quick to recharge with easy magnetic connection
Learning curve with lots of frustrations
Mio Go app
No lock screen in Workout mode
The pictures are of the dashboard layout using Sportstracker and its HR graph. And a pic of the Mio Go screen after the workout. Cannot change it to landscape mode or zoom in.
When the Fuse for some reason disconnects from the Mio Go app during a workout, it will not automatically reconnect. At least not for me. And again the other apps are superior since they reconnect all by themselves. If I wanted to connect to the Mio again I would have to end the workout and reinitialize the HR so the Mio app can find the Fuse.
Update: I've learned to not even use the Mio app other than to control the device settings once in a while. I exclusively use the Sportstracker app (Android only, sorry IOS) and it works great. For swimming laps in a 25 yard pool I strap on the Mio, let it find HR, launch Sportstracker dashboard and go swim. I can glance at the dashboard when I place the phone in a plastig on the wall in my lane. Don't have to touch anything, it's simple. It does't lose the connection and now I'm even more impressed.
Known defect, complete failure after 30 days
by Ashburn, Virginia (1 out of 5 stars)
January 17, 2015
I've changed my rating from 4 to 1 star. After using this device for a few weeks, it displayed a "no memory" message that you're supposed to be able to clear with a data sync. But the sync function with the Mio Go app fails every time halfway through syncing daily records once you get that error. The app hangs up, the data transfer fails, and the device memory won't clear. So the device is useless at that point for workout and heart rate monitoring. I tried restarting the phone, reinstalling the app, etc and only managed to waste an hour of my work out time.
I've come to learn that this product has a known defect where the device fails if you go too long without syncing. The manufacturer doesn't tell customers about the defect or how to avoid it. The only way to correct the defect is to replace the device. They just let you beta test the device for them until it fails and then you spend days corresponding with technical support and shipping devices back and forth.
The device started out great, but it got unuseable pretty quickly.

September 29, 2016
I have been a Mio Fuse user for close to a year now, and while I love the device, when it works, it fails often.
The pros : it accurately records my heart rate during workouts, for the most part. It handles HIIT workouts fairly accurately, and it does a good job of step tracking. It is comfortable, even when sleeping.
The cons : when I sweat, the heart rate monitoring becomes highly inaccurate. I can't workout without sweating. The required android application is a total piece of garbage. The one major flaw with the unit is the rubber around the main part of the unit breaks or separates. This allows sweat or water to get inside the device. This prevents the touch sensitive face from working. So, if you're in a workout and want to stop the workout, you can't. The entire device will continue the workout until you can munge the sweat inside of it away from the touch points enough to exit the workout. This is very difficult, since you have to hold the touch points, twice, for 5 seconds. I've returned 3 units (for my wife and myself) under warranty replacement, and I'm going to have to do it again, soon. I think I'll just give up at this point and move on to a competitor.
Also, the app does a very poor job of recording your daily activities. Sometimes it works, and you'll get a month's worth of daily steps (activities) recorded, and then suddenly it will stop recording them. Once you cross over midnight, the previous day's activities disappear.
I like it so much I hate to even take it off to charge it
by Jamie (5 out of 5 stars)
June 21, 2016
I have been using it for one month now and I hate to take it off to charge it. I am not an impulse buyer so I researched all of the brands and models. I am glad that I settled for this one. Based on the way that I am using it I have been getting 4-5 days between charges.
I would definitely buy this model again.
Pro: 1. I chose this one over other models primarily because to get the features that I wanted I would have had to spend 50% more. Being able to monitor my sleep was one of the top features that I was looking for. I believed that I was not sleeping well at night and so this was a mandatory feature for me.
2. The display is big and can be read with little effort.
3. Once you figure out how to go through the menus it has a good set of features that are well thought out.
4. The controls are easy to use.
5. The color of the Mio is based on the size that you choose. I needed a large and so I have the Crimson one. Even then it was tight initially. The band did stretch out and so now I have a good fit.
6. I keep it on when I am in the pool. I do not expect it to be able to monitor my HR when swimming, but as soon as I stop I can shake my arm a little to clear out the water between my arm and the Mio and it will take a good reading.
Cons: Some of the complaints that others have had are legitimate.
1. Especially when it is new the tangs for the band are a little pointed and tend to catch on things. This can usually be solved by ensuring that the band is snug on the wrist. After several weeks of wear they seem to settle in and they are not catching on anything now.
2. Operating directions. What directions; like most new items purchased these days they always skimp on the enclosed paper directions. You will definitely need to download the instructions from their web site.
3. Firmware. In the directions they tell you that you need to update the firmware to get the ability to monitor your sleep. If the feature exits the firmware should already be on there that enables this feature. The firmware update process was not straight forward and so it took working with it a little.I do IT work and so I am updating the firmware on equipment every day but many people may not even know what firmware is.
4. At this time it seems that there is no PC based app to monitor the Mio where you can see charts of your activity. The Android app is ok but it is always better to have a large display.
5. The android app does not sync easy with the Mio. Usually to get it to sync I have to disconnect and then reconnect it. This is not hard but just one extra step. I have not found a menu sequence on the Mio that actually allows you to initiate the sync process. Maybe in the next firmware update.
All you need to know

Almost sent it back. Then I realized the reasons I wanted to send it back were the false promises that got me to buy it but in the end it was still the best for what I needed. Here is all it does and doesn't do, clearly stated:
What it does:
1- it is the best at taking heart rate (compared side to side with treadmill sensors etc it was a second late but always right)
2- you can swim with it
3- it will sync with Pear Fitness which will sync with MFP
What it doesn't do:
I'm going to write a big chapter because a lot needs to be explained about the product and it's a chain of event. First, there are 3 ways to use this. Let's say mode1 is having the watch on you not pressing any button. Mode2 is starting the heart rate monitor. Mode3 is saving a "workout" (heart monitor needs to be on).
Mode1 does nothing apart from evaluating your steps, distance and calories. Without GPS, not sure how but it does it. Fun part? It doesn't save this anywhere. Just on your watch until midnight. So I guess technically you could write it on a piece of paper every night... Their app does not sync this data. This is the most ridiculous thing I've ever seen...
Mode2 you start the heart rate monitor that is top-notch. Very accurate. Now that's where it really sucks. You could have thought "never mind I'll track with an app". Yeah, if the heart-rate monitor is on the battery dies within 6 to 8 hours top. Also, this info is saved nowhere. It's only for info.
Mode3 it saves! Finally! This will be synced with your phone. Well... The heart rate and time only since there is no GPS in the device itself. You can use the app to use your GPS phone and save the workout directly though. Some people mentioned "hey! I'll leave it in workout mode all day." Nope. Battery will die mid-day.
So, in final, if you just want a waterproof accurate heart-monitor that will pair with your fitness app, buy this! If you want to buy it for all the other stuff, nope.
Great HR Monitoring, Everything Else Bombs Miserably
by GoatShine (1 out of 5 stars)
December 27, 2015
The Mio Fuse does a great job of heart rate monitoring on the device itself. The interface of long-pressing the top of device to put it in workout mode where you can get constant HR is clumsy and you never know if you're doing it right. You have to just keep trying and pray that you end up in workout mode. Getting out of workout mode is just as clumsy. During a workout, it flashes different colored lights to indicate if you are under, in, or over your target HR zone. That's a nice feature. However, the difference between blue and green are hard to discern at times.
ALL INTERFACING WITH THE SMARTPHONE APP IS A COMPLETE BOMB AMD WASTE OF TIME. The device doesn't sync 90% of the time. The app loses your workout data. You are unable to stop a workout. The app is about as intuitive as an old DOS program and it is dysfunctional.
I got this primarily as a HR monitor which it does do a good job. But, for $150 I kind of expected to be able to have other data available or at least have the ability of looking at my HR data for a workout on a graph or something. So, now it seems like I have bought a fairly decent "dumb" heart rate monitor. Not sure what to do with that? Price seems pretty steep for a dumb device. Lord help you if you actually want to track activity on this thing!
Great for This Older Athlete!
by cst000000 (5 out of 5 stars)
March 13, 2016
My only goal was to find an accurate heart rate monitor that consistently works to keep me in my target zone when running and cross training. It does this and so much more. The Mio Fuse app syncs to my iphone. You can set how many zones you want for your percent of maximum heart rate, and it graphs how long you are in each zones. It vibrates when you go from one zone to another. It then tells you what zone you stayed in the most and for how long, your average heart rate, and calories burned. This is great information for athletes! I really feel like it will take me to the next level in fitness. I tend to over train and let my heart rate go to high for longer than I should, (over 90% of my max) and then feel drained for the rest of the day. This will help keep me in the right zone.
I didn't think I would use the step count because I am active already, but it does motivate me to get up and move around. You can also set how many calories you want to burn in a day which keeps me moving too. I do not use the sleep feature because I sleep like a log anyway.
I am an older athlete and technology does not come as easy to me as younger people, but this is fairly easy to set-up. I had trouble with the firmware update but found how to fix it by Googling it. The Mio website was not much help. I did not receive an instruction book so you have to rely on their online videos which were not compete enough for me. I found the best help from other users. It took me several days to get it all figured out. If you struggle with technology don't give up because it is too hard. A lot of times it is just user error. Keep working at it and you will be fine. If this grandma can figure it out, you can too!
The only thing I do not like is that it is not as attractive as other fitness trackers out there, but according to reviews I thoroughly looked at, this is the most accurate. Plus, it is much easier to see for those of use who have suddenly become near-sighted! I tried a couple other fitness trackers, and this is the only one that meets my needs. I think this is a great product , and I highly recommend.
IT IS AN ALL DAY HR MONITOR AS WELL AS OTHER GREAT FEATURES
by Benjamin N. Creasman (5 out of 5 stars)
January 1, 2015
First, I never write reviews but had to in light of two things:
1) the silly things people wrote about this product because they don't read directions or look at the FAQ's on website to trouble shoot their problems
2) this great product
I'm an avid exercise guy. I train 6 days a week and 7 when I can. It's my outlet being a father of 2 young boys and trying to keep up with them! I wanted something that would track my daily caloric burn and collaborate with myfitnesspal app so I could stay motivated by keeping my stats. (Full integration with the said app is coming but for now I just manually transfer my stats.)
- comfortable- you have to wear any HRM two inches above your wrist. If you don't, you won't get a good reading. This is universal because of the ergonomics of your wrist. It has nothing to do with this device. (Ignorant comment by other users on this)
- accurate HEart Rate- it is highly accurate if you wear it right
- screen design and controls- controls are very simple, as opposed to some people who said it's complicated. Pressing one button and holding until you see it say "find" while calculating your HR is something I taught my 5 year old to do.
- ALL DAY HR Monitor- it will track your HR all day if you want without going into "workout mode"; this just will run your battery down in 11-13 hrs as the FAQ's say on their website; simply hold the top button until it says "find" and it will begin tracking your heart rate. It will not enter "workout mode" until you tap the same button again and "go" appears. Then you will have a workout started with timer and stats being saved to the band.
- Step Counter- this is also accurate from everything I can tell. Not sure why others are saying its 1000 steps off. I have not had this problem at all. In comparison to my Jawbone UP, it's almost spot on.
- Future Firmware- sleep tracking is coming soon and the necessary hardware for such is already in place.
- sometimes the disabling of the controls is annoying when I'm laying down and want to check the time; the FAQ on the website states that the device must be upright to enable controls. This is due to their desire to try and limit inadvertent touching.
- notifications assent- it would be awesome to get notifications from your phone on this like the Microsoft Band but this would require and LCD which I kind of like the retro look they chose. It also makes battery last longer
- Myfitnesspal and apple health integration- this is currently absent but their website states that these are coming features
All in all, this is the best fitness tracker on the market from what I've experienced. I love it and interested to see where they go with this product and the general market for such products.
UPDATE: after owning this for a month and putting it through almost 25 training sessions of 1.5-2 hrs each, I am still pleased with this band. The only problem I have found, that others have also noticed, is it will loose my heart rate during certain weight lifting exercises. Not all but some, specifically ones that involved a high level of wrist motion. When doing things like curls or shoulder press, I have found it to work great. But push ups and other exercises that require wrist movement are at times challenging. Other than that, for this price point and what this offers, you cannot beat it right now with current market offerings.
Good heart rate monitoring watch killed by poor software
by Anonymous (1 out of 5 stars)
November 10, 2017
I've had this watch for almost 3 years now and after countless app and firmware updates it still does not sync reliably and cleanly with my Android phone. The heartrate monitoring seems to work really well, but the app is hopeless. Most of the time it starts syncing, gets stuck frequently at certain steps (step 12 of 14, or when syncing sleep data), and then drops the connection to the watch and refuses to reconnect. Bluetooth on my phone works perfectly with other devices. It seems to be some sort of handshaking error between the watch firmware and phone app. The watch seems to be waiting at some step that it can't get out of and the phone app can't reinitiate the communications and continue where it left off.
It takes me anywhere from 30 minutes to several days of retrying to get the data from a single workout to the phone in order to look at the graphed data. Retrying is what their tech support suggests. It does seem to work better with the iPhone app which was needed to update the firmware. You'd think that for such a product they'd test the firmware and software on several phones and platforms or beta test thoroughly before releasing each revision.
If you only use the watch to monitor instantaneous heartrate, daily calories, and steps, then it works fine. If you want the extras from the app, then I would not recommend this product. Note that you still need the app to set up the watch. The Android app seems to work fine for setup, but for the longest time I had to use someone else's iPhone to update the firmware.
UPDATE 2/2/18: I've reduced my rating from 2 stars to 1 star. The two recent updates of MioGo do not work on my Android phone. When I start the software on my phone, it tells me that it's doing some housekeeping and to wait a few minutes. The progress bar shows 0% and goes no further. I no longer have access to my old workout data, and I cannot download and view new data. I cannot sync the time either so it is still displaying Daylight Savings Time.
