That's a really great app. However, there're some problems and things that could be added. First of all, it loves to freeze. It usually takes me three and more attempts to get to the workout. I need to close and open it again until it finally allows me to get to the point. I think the app would definitely benefit from sending notifications and reminders. And it also would be nice to synchronize it with Google Fit or something like that

Don't forget to STOP workout. If you do not press stop workout the day of your workout it counts that day as a rest day and you will lose your hot streak. The app thinks you didn't work out at all after this and pushes all your workout sessions up 1 day on the ladder. and tell you to do that previous days workout again. Also the app initially made it seem like it has a nutrition plan to follow as well but it does not. I wouldn't have paid for an app that is broken with no nutrition suggestions.

The features bought by the new update, the new UI, habit tracker and all have made it terrible!! It was much better back then. We just had to click if we walked 10k steps, click 10 times for 10 glasses of water, check the checkbox for 8 hr sleep. It was so well back then bring that old UI back this new one is so much annoying😭😭
