Cannot alter profile info, just opens the camera when I try. Cannot clear data. I would appreciate a swift update or I'll be returning the wrist band and deleting the app. ### 1/5 — I didn't want to be able to edit my profile anyways *2014-09-24, version 2.0.4* Absolutely the most frustrating app. Whenever I touch anything it automatically pulls up the camera. I can't edit my profile information and it's just pretty much useless. ### 1/5 — No download *2014-08-24* Wouldn't let me download the app. Can't use the product without the app. ### 1/5 — Rubish *2014-08-16* I bought an aldi activity band today it works on this app yet app says incompatible with my iPhone4 my iPad and my iPod help it won't even let me down load just says incompatible :( I wasted £30 on the band and the help numbers in German if anyone finds an app to work this please let me know as all the dynamo app says is can't down load on my iPad or my mini iPad or my iPhone can anyone help with a downloadable alternative to dynamo please HELP ### 1/5 — Rubbish *2014-08-12* I bought this as I previously had a Fitbit (£80) from the Apple store but, after having 3 faulty ones in as many months, got my money back. Saw this but having the same problem won't let me download the app so I will be taking it back for a refund. Obviously, you get what you pay for. Wouldn't recommend buying this! Only gave it one star as it wouldn't let me submit with no stars. ## Most critical reviews (10 lowest-rated) ### 1/5 — Rubbish *2015-03-17* App won't open. Keeps crashing. Very disappointed ### 1/5 — Buyer beware *2015-02-23* Only synced once then app failed.total waste of time and money. Other reviewers are having the same problem but makers don't care and have not fixed any issues. I will be returning my ssmart watch. Buyer beware. ### 1/5 — Crashes *2015-01-13* As above fix it please 👎 ### 1/5 — Dynamo app *2015-01-02* App won't load after syncing with myfitness app. Info not getting to the myfitness app at all!! ### 1/5 — Come on *2014-12-28* App wont open. Ios8 - iphone 6. Taking it back to retailer ### 1/5 — Keeps crashing *2014-12-25* Can't open the app - keeps crashing 😞 ### 1/5 — 앱이 다운되네요 *2014-12-09, version 2.2* 처음 설치하고 동작은 잘됩니다. 앱을 종료하고 다시켜면 안켜집니다. 확인부탁드립니다. 현재 재설치해서 다시 확인하고 있네요. >> my fitness 연동설정하면 안켜집니다. 해결부탁합니다. ### 1/5 — App crash *2014-11-11* Since the latest update the app crashes every time I try to open it. Needs to be fixed soon or I will start losing my data. ### 1/5 — Crashes *2014-11-06* App won't load since trying to sync with mapmyfitness app ### 1/5 — Can't change profile and no support *2014-10-03* As other reviewers say you can't change your profile in the settings so can't be used properly. Emailed support asking when it will be fixed and no response. Very very poor. ## Most praised reviews (10 highest-rated) ### 5/5 — Great straightforward app! *2014-10-05* Really simple and easy to use in conjunction with the Oregon Smart fitness wristband I was given for my birthday. Measures my sleep, calories burned, exercise done, steps taken.... I love it!! ### 4/5 — Update works now *2014-10-06* All works really well now. Nice and straightforward app. Would be 5 stars if interstates with HealthKit. ### 4/5 — Today's update for iOS v8 iPhone 5 works. 😎 *2014-10-05* iPhone 5 iOS v8. Hallelujah now works after today's update. Thank you. 4 stars until I can confirm everything works ok. ### 4/5 — Updated finally! *2014-10-05* Much better now it's updated to work on iOS 8. Would be nice if it integrated with health app and my fitness pal. ### 3/5 — App will not open *2014-11-20* I'm not sure if it's a coincidence but since I downloaded map my fitness app I have been unable to open the Dynamo app?! ### 3/5 — Ok but needs add ons *2014-01-22* Been using for a few days...app is ok but basic for now, needs the option to add activity like a squash game gym session or cycling etc... Only then can calorie count be accurate...also needs an option to continuously stay connected with the band for now u have to always manually update to get data...so ok app but needs much improvement to make it more effective. ### 2/5 — Needs improvement. *2015-07-11, version 2.2.2* I have many issues with the app/technology. 1.) I do an intense interval workout daily for 45min. This app only ever says I did 5 minutes of activity. Never even close to accurate. 2.) it says I am doing over 15,000 steps daily. I don't leave the house much. There is no way I am taking that many steps. 3.) The graph system is the only place I can recall older stats of steps and activity levels. Would be nice to just have an archive of the numbers. I understand that you can't measure some of the things this thing does completely accurate. But this thing doesn't even get close to appropriate recordings. I hope it improves. ### 2/5 — Almost there *2014-12-26, version 2.2.1* Good app, but exporting to mapmyfitness does not work. Looking forward to the update. ### 2/5 — Update is better but... *2014-10-06* Crashes when I try and set wake times, which is ok as I can still use the app, but the app would be so much better if it linked with health, as I could use sleep analysis apps, as well as my fitness to tie everything in to be awesome. ### 2/5 — Not all it could be *2014-10-05* This App is OK at doing what it's designed to do but it could be so much more if it were able to interact with iOS8's new Health app, MyFitnessPal or the hardware would link to Pacer. While it is out on it's own it has a mediocre performance. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
