Let me start by saying this is the best free app period. There is no free app that can beat this. I’ve tried every other one I could find and this is by far the best. I recently used the referral feature to get a lifetime premium. The suggested workouts are nice if you don’t know exactly how to work out. The only things that bothered me were that there were certain exercises that should’ve been there that weren’t and I had to add myself. There is also no way to track which muscles specifically you’ve worked. But these are minor nitpicks and is overall the best workout app I’ve tried.
