SuperFlex: Gym Workout Tracker

Build muscle and track strength faster with SuperFlex. Enjoy quick set logging, 1RM trend tracking, starter workout templates, and seamless Apple Watch integration!

Train smarter. Get stronger. Prove it.

SuperFlex is a serious, private strength-training tracker built for lifters who care about progressive overload — not a social feed.

Smart weights, picked from your history. Stop guessing your next set. SuperFlex suggests realistic reps and loads from your past performance and effort, so every session builds on the last.

Log fast, log everything. Sets, reps, weight, RPE, set types, supersets, drop sets, and rest timers — captured in a clean, training-first interface. A built-in plate calculator shows exactly what to load.

One number for your training. Your Performance Score sums up training quality at a glance and updates as you log.

See real progress. Estimated 1RMs and strength trends, 7-day volume by muscle group, recovery status so you train what's ready, plus body weight, measurements, and progress photos — all in one place.

Yours, and private. No feeds, no followers. Apple Watch companion, Apple Health sync, and a Live Activity for your workout on the lock screen.

Built for: strength training, powerlifting, bodybuilding, and hypertrophy — beginner to advanced.

Download SuperFlex and make every set count.
