I used to use Iron on iOS, which a very minimalist, open-source gym tracker, that does what I needed it to, in a very simple way. It allowed me to create workout plans, I could edit/add new workouts and machines, and had rest timers. During the workout I was able to log reps to my sets I’ve set during the workout routine setup.
I’ve switched back to android recently, and this app is the only thing I really miss. The closest I got was Flexify, but for some reason, when I finish a workout, the plan doesn’t reset, so next time I open the plan, it’ll be pre-filled by last time’s data. Other than this, it seems to do what I need it to do. Does anyone have a recommendation? Or is there something I miss about Flexify?
I guess it depends on what you are planning to do. Me for example: I don’t really have a workout plan but train more as I feel with my goal being getting as much volume per big muscle group as I can (timewise). So I just use Track n Graph. It’s also kind of my all purpose app for tracking stuff. That way I don’t need many apps.
