Ratings and reviews

Best workout app I've used. The program is easy to use and provides an option for 3-5 days a week, and options of a full gym workout, an "express" workout if you're short on time, and a home bodyweight/resistance band workout. All exercises have a long list of substitutes. This flexibility is great and helps with consistency. Based on your inputs, the app will suggest what weight you should use and how many reps. In just a month I broke through a plateau of 70 lbs on bench and an now at 85 lbs

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.
