worth it!

Had a hard time keeping track of my workout routine. Writing them down became a chore and I didn’t want to be doing it while I’m working out. Glad I can set up my workout routines with a tap and I love that it keeps track of stats as well.

Best fitness app I’ve ever used

I barely ever write app reviews but feel like I owe it to Rep AI given how much it has helped my relationship with the gym. Being able to easily see previous weights and reps week to week, and enter the data seamlessly... game changer.
