This app looks to be the best of the bunch, but only because nobody seems to have written a great workout tracker. Lots of stuff is broken: I frequently have to restart to get into workout & exercise menus, reordering exercises works sporadically, workout charts are inaccurate (it still says 0kg for my leg exercises on a few charts) etc. The interface is also confusing; sometimes you swipe to delete, sometimes you swipe to share. The paid-for convenience features are nice (auto populate last set and weight #s) but yet theres no "preload my last workout" button. If they do make one, itll likely be in-app purchase.
