Get a new name if you won’t support the stuff of the „old“ company ### 1/5 — App não funciona *2022-01-08* O aplicativo simplesmente não abre, fica dando mensagem de erro de conectividade com a internet ### 1/5 — Was great until it wasn’t *2022-01-01, version 1.1.1* So the app won’t open anymore? And I can’t find the developer website? Not cool. ### 1/5 — App does not work and website is down with a 403 error *2021-12-18* I will change this review when problem is fixed. I feel ripped off because I can’t use my device after paying good money for it. ### 1/5 — App dropped without notice *2021-12-15, version 1.1.1* Throughly enthralled with device and app until Mio Labs dropped support without explanation. Mio Pod still sends heart rate to Garmin Edge though. ### 1/5 — Mio fuse *2021-12-01* please make an application for mio fuse ### 1/5 — Zero functionality since last bug fix *2021-11-19, version 1.1.1* I have been unable to even open this app since prior to the last bug fix. Since then the country list has been restricted to China and the US. Which means I cannot even sign in to troubleshoot with MIO Support. Will change to another HRM if unable to use app and leverage data collection and analysis. Please restore service to Canada. ### 1/5 — Не работает *2021-11-12* Купила новые часы мио, а приложение тупо не работает !!! ### 1/5 — I don’t even think they exist anymore *2021-11-03* Bought one a year ago, now nothing works, facebook page gone, contact info gone. Waste of money. Why not just tell someone you are out of business. ### 1/5 — Frustrating *2021-10-26* I really like the functionality of this App but looks like it from time to time it didn’t work for many days . I delete and install again, the menu only show USA and China as country options y I can’t log in because the app can’t reach the server . ### 2/5 — I Want To Love It *2021-10-21* I seriously want to love it, the app has some awesome features and my MioPod is very cool. However, the app almost never works the way it’s supposed to. It’s frustrating and honestly for someone like me who likes to see the results, it’s discouraging me from completing my workouts because my data never syncs or the server is down. Always something. If you are considering this app/device I would try something different. ### 1/5 — What’s going on??? *2021-10-11* Left the house for my walk this morning with my arm band on and I tried to open the app and it just keeps closing out. What’s the story here? So now I can’t use my heartbeat monitor? I haven’t even had this for six months. This is ridiculous!!! ### 1/5 — Doesn’t open *2021-10-03, version 1.1.1* Since upgrading my phone to iOS 15, the app won’t even open. ### 1/5 — App Crashes Immediately *2021-09-28* I have endured the glitches and kept using this thing, but now the app doesn’t even open. I have the current HR monitor- so it’s not the fault of older hardware. Probably not going to ever see the data from that workout. 😒 ### 1/5 — Mio Alpha 2 *2021-09-25* Und wie soll das mit den etwas älteren Modellen funktionieren? Die Industrie zwingt zur Wegwerfgesellschaft :( ### 1/5 — For MIO Fuse???? *2021-09-01* What application do I use for MIO FUSE? ## Most critical reviews (10 lowest-rated) ### 1/5 — Приложение не работает *2024-06-01* Ваше приложение не работает. Пишет что, - Нет подключение к интернету. Являюсь пользователем браслета Mio Alpha 2, и просто не могу им пользоваться. ### 1/5 — Can you give negative stars? *2024-01-23* This company is trash. They sold products that still function but they ended the app used to pair them? Hopefully I can see my battery life in another app but now I can't update my zones. ### 1/5 — No support *2023-07-25* That they refuse to support the older products is ridiculous, like a bait and switch. Here, buy our product, now watch us remove the app for it so that you have to buy a new product and use the new app. ### 1/5 — Fuse no longer supported *2022-09-05, version 1.1.1* I never felt so betrayed by a company before. Imagine screwing over the customers that bought and were loyal to your product! Sadly I really like my MIO-Fuse, but I will NEVER abut anything from this company again. ### 1/5 — Add Mio Fuse support. *2022-06-21* Totally lame behavior to get rid of old devices support. Absolutely unacceptable for the company looking after their reputation. Shame on you, guys. ### 1/5 — App doesn’t work even with the MioPod *2022-06-17, version 1.1.1* Although they say this App doesn’t work with Legacy old devices it doesn’t even work with the new one the MioPod. You can’t even create an account. ### 1/5 — Alte Uhren sind jetzt nicht mehr nutzbar *2022-05-19* Nie wieder Mio fuse! Kann ja wohl nicht sein!!! ### 1/5 — Кинули своих клиентов *2022-03-22* Являюсь обладателем браслета Mio Fuze,и не могу в полной мере его использовать,т.к компания решила произвести «ребрендинг» и кинуть своих покупателей.Старое приложение теперь не работает,а новое не поддерживает коннект со всеми прошлыми устройствами👎🏻 ### 1/5 — Lack of support. Can’t even get an email back. *2022-02-25* I can’t even get the support group to email me back. I have a Velo I purchased just last fall and the GO app is no longer supported so I can’t change HR zones. This is their new app but it won’t support anything but the POD. It would have been nice if they had left the MIO GO app active. Time to switch heart rate monitors but I won’t be getting another Mio Labs monitor. ### 1/5 — Horrible support *2022-02-15, version 1.1.1* Only gave it 1 star because I had too No longer supporting product, terrible business ## Most praised reviews (10 highest-rated) ### 5/5 — Daily User *2020-09-24* This is a great heart rate monitor. I love that it shows you what zone on the strap. ### 5/5 — Forget a Fitness Watch *2020-07-29* One of the best products I have purchased in a long long time. Exact constant knowing of my heart rate and when to slow it down. As a heart attack survivor and still wanting to workout, the MIO is perfect. I have tried smart watches, but they were so unreliable. The MIO is exact and I know instantly when to back it down. Great product, no issues, excellent product. ### 5/5 — Miopod *2020-07-13* Excellent product, had several chest stap monitors in the past and they were very intermittent in working and collecting day. Not one issue with the miopod. I use it paired to my Garmin 1030, pairs supper fast and have had no issues. App is great as well. ### 5/5 — MioPOD - The Best HR Monitor & App For Performance & Value *2020-07-09* I’ve had several Mio products in the past and always had good experiences. I loved my MioAlpha2 and Mio VELO and I was disappointed when they were no longer supported. Hey, nothing lasts forever. Then to my surprise appeared the MioPOD! Admittedly I didn’t hesitate, I just ordered one. I had no idea - I’ve been blown away! Far more comfortable and accurate than any chest or wrist monitor I’ve owned to date. Pairs quickly with every device I’ve tried it with. The colors prompts on the MioPOD keep you apprised of where you’re working in your HR zones. Even better it utilizes (5) FirstBeat performance analytics (and Vo2 is being added soon I hear - SCORE!) which are displayed in the App. If you’re not familiar research FirstBeat analytics because the MioApp blows all other apps away in the presentation of your training data. I’ve done the Garmin’s and Huawei Band 4 Pro and they don’t even come close - hear me - NOT EVEN CLOSE!! I’ve had zero issues with the monitor losing connectivity or HR readings. I’ve had no issues getting support feedback/answers from Mio. If you’re having issues with the App I respectfully suggest studying the FirstBeat features because the App gives you everything in a easy to follow format. Okay, there is one thing - I wish the face of the monitor (center where the Mio logo is) displayed your real time HR reading. Maybe with Gen2 Mio? :) ### 4/5 — Great training aid *2021-04-13, version 1.1* As a previous customer of the legacy MIO LINK I wanted a more in depth analysis of my workouts. This app with the New HRM gives me that; I’ve not tried the subscription service yet as it does look a little pricey for an online offering in an app. ### 4/5 — Cool data! *2020-06-24, version 1.0.3* Doesn’t show a running time when it’s turned on but love all the cool data that it comes with! Can’t find any data like that in any competitor! Will recommend ! ### 3/5 — Love it but new update keeps crashing *2021-12-02, version 1.1.1* Help Mio! ### 3/5 — Don’t update!!!! *2021-11-06* Had I not updated, I would have given it 5 stars. After the update a month ago, the app stopped working. It crashed every single time I tried to launch it. Today, I decided to uninstall with the hope that reinstalling would help. Instead I’m logged out. The app says network access failed, please check internet connection on phone. I have a mio pod device which doesn’t seem to be the legacy kind. ### 3/5 — App no longer works, MIO-labs website gone *2021-10-22* Don’t do the upgrade! This app was great until I updated it a couple weeks ago. I haven’t gotten it to work right since and it no longer saves my workouts. Tried to uninstall and reinstall and keep getting an error message when I try to login that my phone isn’t connected to a network—it is. Tried to go to the website and it no longer exists. I searched the internet and found a forum where others complained of the same. I think this company went out of business. Maybe it will still work for you if you don’t upgrade. 🤷‍♀️ ### 3/5 — For Mio fuse sync *2019-12-12* This app is Mio Go app replacement But it doesn’t support older devices, I own two mio fuse devices older Mio Go app is not in AppStore this app does not support Mio fuse Update: There is workaround App which are no longer available will be shown in purchased history old mio app will be available (only if you have already purchased) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
