All this App's heavy lifting comes before and after your workout.  While at the gym, just click 'Done' when you've finished a routine.  Version 1.0 is Free with No Ads or BS, but donations to fund this and my other projects are much appreciated.

A huge list of workout routines to choose from.  Add your expected Reps, Sets, amount of  Weight you expect to lift, and Save.  It'll show up in your Checklist ready for your next gym visit.

MuscleRep is super private.  The only outside connection it has is to allow Software Updates. Anything you put in this app is controlled and owned by you, including Notes & Photos [which App does not  save to phone library].  No ads & No data capture.  

Behold... a handcrafted Progress page!  Basic at the moment, but I have lots of ideas to improve visualizing your stats.  Even with the basic data you record, it's enough to view trends, change'r up, and get the most out of a session.
