This is, without a doubt, the most flexible, customizable and useful gym app Ive seen. Easy to use with features that just make sense. Everytime Ive wanted to do something (eg edit a routine on the fly, change the log, etc) Ive been able to do it.
My only complaint is the monthly fee. While I dont mind paying for features $5-$10 a month is a little excessive and will add up over the years. If they keep adding content I get it, but since I use only my custom workouts I doubt I will use any new content.
