Track every rep.
See every gain.
You train hard. You should know exactly what's working. SuperFlex logs your sets, reps, and weight in seconds — then turns your training data into clear charts, 1RM estimates, and progress photos you can compare side by side. No spreadsheets. No guesswork.
Built for powerlifters, bodybuilders, and coaches who want more than a spreadsheet.

Your mirror lies. Your photos don't.
When you train consistently, changes happen so gradually you stop noticing them. SuperFlex's progress photo manager solves this. Snap a photo, tag your bodyweight, and compare any two dates instantly. Three months of consistency looks unremarkable day to day. Side by side, it's undeniable.
Photos stay on your device — private by default, encrypted if backed up
Guided camera overlay so every photo matches the same pose and angle
Compare any two dates side by side — instantly see how far you've come
