I like the program, this is a review of the app. Twice it has lost all my previous logged workouts. It consistently asks me to resume the workout if I navigate to a different screen and will be slow and lose some records when resuming. Currently it won't register the 'complete workout' button so I guess today's workout (and new PR) are unrecorded.

The program itself is five stars but the app is so glitchy. Seems like once a month the app is totally unusable. Today the app says to update it to work even though there's no actual update. I'm editing my review on 3/5/26. they released an update today is complete garbage. if you log a warm up weight it gets rid of the info that tells you the weight for your working sets. the complete workout button just doesn't work at all. you can't even save your workout. this app is almost unusable.

I'm a returning user. When this app initially launched I used it for almost two years. It was buggy back then. After being gone for over a year I had hope that changed. In the past two months the bugs have got me wanting to leave again. I came back in August and had one or two workouts not save "Oops something went wrong appears." Well that has been almost weekly the past two months. I've uninstalled and reinstalled the app several times. Still, I'm loosing data. Other than that it's a 5/5.
