Review: it's good but the app ruins everything - This product seemed like the perfect device for me. I looked at youtube reviews and they all said that the device had a pretty good heart rate monitor but not that great of app and lacked fancy functions. This seemed fine to me. I wanted something that tracked my calories and told me how hard I was working in the gym. For the most part the heart rate monitor seemed pretty accurate in most cases. I would workout and it would it was consistent with the monitors the gym lets you use. When I was lifting it showed that my heart rate stayed up there which is what I wanted to see. A really great feature, one of the reasons I wanted this watch, was the color coded heart rate zones and the vibration that alerts you when you change zones. All of this seemed to work well with my gym workouts. The heart rate function was poor when doing martial arts. It was very inaccurate. It would say my heart rate was high when I was doing nothing and low when I was doing activities. I mostly bought it for the gym so this wasn't all that important. What got this watched returned and a one star review was the app and little irritating things. As others have mentioned the buttons on the device are hard to activate sometimes. Other times they are easy to use. They only want to work when they want to work. The biggest most frustrating thing ever is that app. I knew the app wasn't that great, but this is ridiculous. It doesn't sync your workouts and only sometimes syncs your daily activities. I got it to sync once, and the detail of the heart rate graph was just terrible. The daily activities only show the basic overall steps and calories and what not for your day, there is no way to compare. And that is when it syncs, most of the time it will partially sync your daily workout, sometimes not at all. Sometime the app doesn't even recognize that your watch is right next to your phone, even if you do everything right. But really this watch is good and the app is so bad it offsets the good. Maybe if they ever fix the issues with the app I might get it again, but it is to frustrating to have right now. I don't recommend purchasing it, because without a decent way to interpret the data, its pretty much useless.
Review: Decent HRM hardware, but its app is subpar and under-report calorie by 35%-55% in workout mode! - Final Review on this Mio Fuse. I will keep it 2 stars after 1 month use. Here are the breakdowns: Hardware overall : Score 3 stars Look/feel: - 3 Star It is not a piece of product you will get compliments from wearing it as a watch. People may not even notice that. It was made by some sort of black rubber/silicon. If you are wearing it in the gym, it is fine because your goal is to maximize your workout with this product, not about showing off a piece of gear. If you are one of these, you will be disappointed. Touch/button design: - 2 stars The two side buttons on the screen used to change different information on the device are fine. However, the top button to get you in and out of the workout mode (most important function IMO) has serious design flaw. You can't really see it with your eyes due to it blends in with all black color. It takes several tries to get in or out of workout mode for me every single time. It frustrates me. In addition, because it is out on the surface, it is very very easy to be accidentally pushed/pressed during the workout. There is no vibration notifying you about that. It means you may miss a chunk of your workout recording by the end. It definitely drives me crazy when it happens. I am sure it will do to you too. location of wearing: - 3 stars As suggested, it must be worn about a few inch above your wrist bone for more accurate HR reads. If you are doing aerobics or high intensity workout involving arm movement, Mio fuse may slip down from the preferable location unless you are wearing it with very uncomfortable tightness. I guess it applies to all wrist wearing HRM so it will be an industry flaw not only Mio's to be fair. HRM accuracy: - 4 stars It is not bad. Definitely not as good as chest strap and it does give you some weird low HR numbers from time to time every workout. But for tracking an overall workout, it gets the job done. Also the HR displace stays on during the workout, so it is very easy to see your workout intensity right off the wrist. Software/App - Mio Go - 1 star I really want to like this product due to its pretty accurate HRM. I can see all those heart rate #s, but by the end of the day, it must give me an accurate calorie burnt number. Mio Go completely blew it on this. Using Mio fuse as same single source of heart rate, I compare over and over again with Endomondo, Wahoo fitness app and Mio Go. Mio go's calorie burnt number after EACH workout was 35% to 55% lower than the other two apps and the other twos apps designed by completely different company provided almost identical calorie #. It is UNACCEPTABLE! Unless Mio can prove that their calorie calculation algorithm is accurate and others are not, its app completely discredits people's hard work. I repeatedly wants their customer service to post something regarding this issue. So far, I have NOT seen any. Also, the inaccurate calorie # can NOT be shared with health app or the most popular myfitnesspal app. They said they are working on the integration with apple health app but no plan for others yet. The sync between Mio fuse and Mio go can be buggy from time to time. The workaround: If you maintain the faith of Mio fuse for future improvement and not return the product, you have a workaround to use Mio fuse as HRM but use Endomondo, Wahoo fitness or other fitness apps to track your calorie. The drawback of the walkaround is that you now have to keep your phone with you during the workout at all time due to bluetooth connection. You can NO LONGER enjoy the benefit of sync data later function. Words to Mio: You have a piece of decent HRM hardware. Please please get your developers together to fix your software. Your calorie # is way way off. and for next generation mio fuse, relocate your workout on/off button. Old testing review: ****** This review will be updated based on more experience I have with this product. It will be ended either I keep it or return it. I have had Mio Fuse for 3 days now. I had pretty high expectations for this product based on the reviews I read and would love to give it 5 stars if it suits my needs. My purpose of buying this product is to replace my Wahoo Tickr HRM chest strap for 1) accurate active HR reading (training with heart) and 2) its late sync ability (go with iphone free while workout). So far, NOT so good... During the next a few weeks, I will wear both mio and Wahoo TickR to do various workouts in the gym to compare their data and functionality. Day 1: Weight training The app set up was easy and took me 2 mins. I worn Mio half inch above my wrist bone and started to do weights, bench bar bell, dump bell, cable, etc. I noticed that Mio and Wahoo had some different reads, a lot of time Mio's HR's read is 20 beats lower than Wahoo's. To avoid user error, I moved Mio to about 1.5 in above my wrist bone and tightened it really good. The read consistency has improved a bit, but sometimes still 10-15 off Wahoo's. When I moved to side arm raise machine (your forearm and wrist under a padded component to raise up working on your side shoulders), accident happened. The top bottom designed to start and end a workout by pressing and holding were switched off because of the wrist position from the pressure of the pads. So I had to manually turn it back on after noticing it was off (no HR read). It happened twice : workout start -> ended by accident, then start again (manually) - end by accident again, then start again (manually). I guess I will need to turn Mio inwards next time to avoid this situation. But that workout on/off button was designed too much on the top surface of the device, it will be very easily turned on and off by accident. It has to depend on the app to determine whether it is an accident or really a workout circle (more on this later). Then I moved onto rowing machine and treadmill, Mio works very well on those tests with almost identical reads with Wahoo's. Sync time: After I completed my workout, I synced both Mio and Wahoo with their respective apps to see the final result. BIG PROBLEM: Wahoo gave me 1:15 time and 573 calories with average HR 107 and Max HR 156 and Mio gave me 35 mins and 225 calories with average HR 121 and max HR 158. It means Mio somehow ignored my 30 mins workout. I don't know if it was due to the accidental in and out of the workout mode. But even though, why didn't it just display 2 and/or 3 workouts but erased my entire first part of the workout?!? - NOT VERY HAPPY. Day 2: - Boot Camp The Mio held up well on its HR reads comparing to Wahoo on this one hour test. The problem was putting up boxing gloves to do punching bags, Mio was on its way again. I had to put it all the way up on my forearm to avoid any accident contacts to the top workout button. So it didn't get turned off at all during the workout. Sync: Wahoo was as reliable as usually give me good read of all the information I needed, but Mio did NOT give me anything after sync. Yes, it was on workout mode the entire time (I know it because I kept watching its HR read on display) and I turned it off by the end manually. ZERO workout! I thought it probably had some sort of delay. So I kept trying and even tried after mid-night when it gives out daily activity, Daily activity got synced but my workout NEVER show up. So it ate my 1 hour workout just like that! - I am OUTRAGEOUS! The problems after 2 days: 1) The workout on and off button designed problem and place it on the very surface of the device, it can be easily turned on and off by accident. Edit: Mio recommended to wear it upside down but how about wearing boxing gloves, how do I avoid that? 2) A huge flaw after an workout being accidentally ended, then restarted, the app can NOT figure this out and will cut off the previous workout Edit See my edits to 1) and 3). 3) The app or device erases your workout out of blue (super UNreliable if that's the case) Edit: It is resolved due to user error 4) I have no clue how to sync it to other apps, there is no such an option on mio go app. Edit: Was able to sync with Endomondo, but it raises the other issue - see below. ** Day 3: Weight training again First of all, I learnt that I must tap the top button to get GO after pressing + holding it. So i am more comfortable about not losing my entire workout going to gym. And I was able to sync endomondo with it as well. So this time, I had my wahoo synced with wahoo app and Mio fuse synced with Mio go and endomondo simultaneously. During the workout, I still saw strange HR read on fuse. i.e. When I was doing pull up, all the sudden HR read dropped to 61 while wahoo told me it was 110. Obviously 61 was incorrect. So I just snug/move it around a bit even it was really tight on my forearm/wrist already. 5-10 seconds later, it eventually went back to the similar read as my wahoo. I don't really understand what it happened. Was it getting loose during my movement (doubt it) or somehow the wrist HR detecting technology causing problem. I do not want to consistently checking my HR during the workout because of trusting issue. Anyhow, the final sync was successful but the results made me scratch my head. Mio Go: Time: 1:23 | Avg HR: 103 | Max HR: 142 | Cal: 347 with Mio fuse Endomodo (weight training mode) : Time: 1:23 | HR range: 61-142 | Avg HR: 104 | Cal: 625 with Mio fuse Wahoo (weight training mode): Time: 1:23 | Avg HR: 106 | Max HR: 143 | Cal: 616 with Wahoo TickR Chest Strap While everything else was about the same, the calorie count discrepancy between Mio Go app and other apps is HUGE. Even Endomodo and Wahoo were tracking data via different HRM devices, the result came out about same. Mio Go app gave me 45% less calorie count. I am not an expert on this but I have to trust the similar # here. Mio Team: Please provide me your insight on this topic. Also I tried to lock all buttons via Mio go app after I entered the workout mode. It did NOT work. I wonder if anybody successfully made it happen. So the risk of the workout button being pressed can NOT be eliminated on software side. Since my last cardio workout got lost (user error on day 2), I will test it out again tomorrow. The subject is Insanity workout. Stay tuned! Oh I bumped my rating to 2 stars after today. *** Day 4: Interval Cardio - Insanity plus extra aerobic training I didn't have time to compare Wahoo strap and Mio fuse during the workout because my phone was playing Insanity video. Here is the final result - still very baffling Mio Go - Time: 1:23 | Avg HR: 123 | Max HR: 167 | Cal: 552 - with Mio fuse Endomodo (Aerobic mode) - Time: 1:24 | Avg HR: 124 | Max HR: 167 | Cal: 859 - with Mio fuse Wahoo (Cardio mode) - Time: 1:24 | Avg HR 125 | Max HR: 162 | Cal: 863 - With Wahoo TrickR strap Once again, Endomodo and Wahoo gave me similar reads especially on calories counts even with completely different HRM devices but Mio Go app had 36% less cals. I really need an explanation on that. The Mio App's late sync function that I think I finally can workout free from a phone around. If you are a new fitness tracking device user and not experience with all other apps and such, you are fed with very deflated cals # by its original app. Is it a way to encourage you work out more? I don't know and I need an answer. ****

Mio Go: Time: 1:23 | Avg HR: 103 | Max HR: 142 | Cal: 347 with Mio fuse Endomodo (weight training mode) : Time: 1:23 | HR range: 61-142 | Avg HR: 104 | Cal: 625 with Mio fuse Wahoo (weight training mode): Time: 1:23 | Avg HR: 106 | Max HR: 143 | Cal: 616 with Wahoo TickR Chest Strap While everything else was about the same, the calorie count discrepancy between Mio Go app and other apps is HUGE. Even Endomodo and Wahoo were tracking data via different HRM devices, the result came out about same. Mio Go app gave me 45% less calorie count. I am not an expert on this but I have to trust the similar # here. Mio Team: Please provide me your insight on this topic. Also I tried to lock all buttons via Mio go app after I entered the workout mode. It did NOT work. I wonder if anybody successfully made it happen. So the risk of the workout button being pressed can NOT be eliminated on software side. Since my last cardio workout got lost (user error on day 2), I will test it out again tomorrow. The subject is Insanity workout. Stay tuned! Oh I bumped my rating to 2 stars after today. *** Day 4: Interval Cardio - Insanity plus extra aerobic training I didn't have time to compare Wahoo strap and Mio fuse during the workout because my phone was playing Insanity video. Here is the final result - still very baffling Mio Go - Time: 1:23 | Avg HR: 123 | Max HR: 167 | Cal: 552 - with Mio fuse Endomodo (Aerobic mode) - Time: 1:24 | Avg HR: 124 | Max HR: 167 | Cal: 859 - with Mio fuse Wahoo (Cardio mode) - Time: 1:24 | Avg HR 125 | Max HR: 162 | Cal: 863 - With Wahoo TrickR strap Once again, Endomodo and Wahoo gave me similar reads especially on calories counts even with completely different HRM devices but Mio Go app had 36% less cals. I really need an explanation on that. The Mio App's late sync function that I think I finally can workout free from a phone around. If you are a new fitness tracking device user and not experience with all other apps and such, you are fed with very deflated cals # by its original app. Is it a way to encourage you work out more? I don't know and I need an answer. ****

### ⭐⭐⭐⭐⭐ Non-Cyclist, Non-Runner - but all round fitness/training? MIO Fuse is for you (update SO I THOUGHT)
*by T***E on December 10, 2014*

Update 03/04/15: Item returned. Got frustrated with the lame and boring looking app which wasn't giving me the information I wanted. There have been promises about updates of different capacities that are just taking too long for me to enjoy this item. (sleep tracking - not urgent for me, but has been mentioned, still not here yet) - (logging meals - they're waiting on MFP or sometign of the sort...- ), I don't go running/cycling very often, so syncing with runkeeper/strata, etc does nothing for me. I do mostly weight lifting and HIIT workouts - non of which are there for me to add as the type of workout I did/do. I'd like to compare my progress from the last time a certain activity was done, there's no way to do that since i cant even list the activity I actually do. The app shows your activity as just one list of daily events - that's it. Thanks for the one update as to being able to tell the battery level, but it's just not enough information for me to actually use in this app. I threw in the towel when the app started being erratic with saving/showing my daily activity. It either erases the previous days activity or doesn't show my culminated activity at the end of the day. Thankfully the company did offer to replace it, but when I considered how much the app just wasn't the thing for me, I was happy that amazon was accepting the return, and so I wouldn't have to worry about the dated UI of the app once and for all. I know I probably sound like a spoiled brat - sorry - thanks to Jawbone UP app for spoiling me. The device does everything it advertises, but the app - ugh,I just cant anymore with it. I'll go activity-tracker-less for a while and see what else comes out during the course of this year. Original review: Seems most of the other Activity/Fitness trackers are more geared toward runners, and some even now towards cyclists. I'm wearing 3 trackers on my arm currently and decided to do a 16.5 min workout which incorporated crazy hand moments (jumping) and no hand moments (planks, etc). The Basis only recognized your workout (albeit automatically) when you start something with hand movements and sustain nit for a while). For my purposes - NO BUENO, because it told me I only worked out for only 4 minutes. Forget when I decide to do weight training... I need something that I can say, "hey, I'm about to workout now. Don't worry about what I'm doing just tell me how many calories I burnt based on my effort". And this is the device for that purpose. I've had a jawbone Up for a year and half, and while I love the concept, the ability to tell it , "hey, I'm gonna workout now so separate this from everything else" and love love love their ap, it's time to get divorced. After 4 malfunctioning devices in less than 18 months, I'd say that's a wrap. Plus, I am curious as to a more accurate expenditure of energy during my workouts because telling the UP app that I did Easy, Moderate, In the Zone, Difficult or Gut Busting effort is pretty relative and I often find myself not being sure where my effort fell. So far, I'm getting everything that the Fuse advertises itself to be. It didn't loose my heartbeat not once during the craziness of jumping around, Cant say the same for the Basis Peak. It spent about 1/2 the time searching for my heartrate. boooo. Love that I can get the information just about my workout while Fuse is workout mode. Like steps, calories burnt so far, distance...which I found helped me to push when I saw that the workout was almost over and I had only burned 90 calories so far when I thought for sure i would easily get 200 calories in this workout. It helped me push harder than previous sessions of this same workout. Love too that after uploading the workout to the ap I realized that even though I surely thought I was gonna die, it really only classified as a "Light/Moderate" workout. Hence, I have much much room for improvement in my fitness. Yes, I wore the Fuse as suggested, and have it pretty darn tight so it wont budge. I'm sure that helped withe getting a constant heart-rate reading during the workout. It also seems well suited to last a while based on the construction. And this review shall be updated every so often so say whether or not I'm still in love. Step count: I manually counted 89 steps and checked back with the 3 devices to see: Basis Peak: 89 Jawbone Up: 82 MIO Fuse: 80 Close enough. Impressed that I activated my device at 2:45 in the afternoon and it told me that I had already burned over 800 calories already that day. Perfect! The algorithms were at work to catch up. I cant say the same for the Basis Peak who didn't even try to catch up on where I was that day when I activated. it only accounted for what happened during the time wearing it. It's hard not to compare the one device with the other because they appear to market to similar if not the same crowd. I've also decided that after having/using Sleep tracking for over a year with the Jawbone UP, it's really just a novelty and the interest quickly wanes. After-all, if you woke up tired, you probably didn't sleep well. There! Anyway, i wont miss it with this device. About that "constant heart-rate" thing: Soo, you're siting there watching TV and eating chips and decided, "hmm, what's my heart-rate?" You can simply tap and hold the button for workout mode, see your heart-rate and turn it back off. This might show up as a 0.0 minute workout when you sync to the app, but it's easily delete-able. It's nice that they have options for you to tell the app what kind of workout you did. So far I don't do any of those things regularly for my workout so I'll leave it as unspecified, but it's a nice touch, and I'm sure more options can easily be added in the future. Maybe MIO can consider having us write in our own activity type too until then. Off to return the other two rubber bands to the store.
