anyone use a phone app to track your workouts? i started lifting again, and my OCD helps here. years ago, i tracked each set, rep, weight, etc. was easy to know if for each exercise what weight i should start w/. i do a lot of 12/10/8. if on the 3rd set I can do 9 or 10, i know next rotation of that exercise should start w/ 5 more pounds. I can't find an app that tracks that granular. Most that I find on the app store let you track an exercise (barbell bench, dumbbell curls, etc.) and the time you spent doing it. I don't see how that would help anyone.
