This is my favourite paid app. Most worth the money. Clean interface. Never crashes an frquent updates make this app well worth the six bucks.
My only suggestion is creating a custom exercise category. For example I want to log a Clean&Press but there is no Full Body category so I just stuck it in the forearm category. If you feature that in your next update, well, I think I just may have tears in my eyes.
update : please make it so I can add category to the exercises!! there have been several updates not including this!!
