Great Workout App
I started using GymBook recently and am very pleased with it. It took me one try out session to decide to buy the Premium IAP.No extra cost other than that and, pretty important to me, my data stays on my device and isn’t collected and sold. Functionality-wise everything is there. Lots of exercises and new ones added frequently. Helpful muscle-map to see what muscles you are using in a workout and lots of stuff to help you throughout your workout. I think the look and feel is a bit sparse, so there is some room for improvement. However, it is great to use as it is!
