>>76316638 (OP)I've been using an app called Gym Day. It's free with no ads, but there are some premium features locked behind a fee. Fortunately that fee can be a one-time purchase instead of a monthly subscription. That's largely what attracted me to the app in the first place.
Functionally, it gets the job done. Create your routine, track your performance, etc. It does suck that there's no algorithm to help with progressive overload though.
If someone made a free version of the RP Hypertrophy app with the algorithm helping with progressive overload, deloads, and overall performance, that'd be based.
