Stops working. Was working well and all of sudden stopped working on Android. Now, I am trying to set up and not receive a text message to complete the connection. If it is an international app, then e-mail should also be a way to complete registration. What is worst is fitness data for months has been lost. Disappointed. Again had an upgrade today 9/11 and now it is crashing. Will again loose the data until a newer version with fixes is released.

Very poorly made. 1. After the last update the app won't even start, it is crashing everytime I try to start it. I uninstalled and reinstalled the app but that didn't fix the issue. 2. Whenever I sunc the app and the watch, most of the time only the steps data is transferred and the sleep, heart rate, and other activity data is not transfered onto the app from the watch.

Very poor performance. I am unable to open an account in the app. When I enter my number, the OTP does not arrive either via SMS or WhatsApp. If I try using my Google account, the 'Verify you are not a robot' task begins — which is even more frustrating, because even after selecting the correct pictures, it does not proceed to the next step. Now, it feels as though we also need to 'verify' the developers’ abilities and qualifications for creating and running this app.
