Generally good. Great for being consistent and keeping track and history of what you did and doing. Not great at making plans for anything above beginners. The library is decent but seems to miss some exercises and equipment. It also crashes if you are listening to music, have the rest timer going, and try and respond to a post.

The app itself is nice, especially now that I've upgraded to the plus while on sale. Couple critiques: -Wish there was an online portal through which I could schedule, browse workouts, etc -I can't seem to bulk plan days/weeks ahead. I'd love a "repeats every..." button. I have to add each individual workout every day that I plan on working out. I can't easily pre-plan a training block

3.5 stars. I enjoy the app and I started the trial; I want the auto rest timer (sketch to keep that behind a paywall btw). Biggest disappointment is the app doesn't calculate progressive overload; standard for training apps these days. I like the exercises available and the videos of them. The workout plans may come in useful. I probably won't use coaching, so it makes premium a tough sell. If a progressive overload feature was available I'd buy immediately. Will see how trial goes.

Glad that you enjoy the app and I appreciate the feedback here! We're also very excited about a guided progressive overload feature, which is on our near term roadmap. We'll update here as well once this has been released!
