Ive used this a handful of times now since owning it. The app is cool but can be a bit glitchy. Ive had it crash numerous times now. If you're listening to music in your gym through your phone, using the app's recording feature can stop the music from playing which is annoying. I also wish (unless im unaware) that you can create your own exercises besides the ones they just offer, and be able to go back and look at them
