RepFlows generates personalized workouts in seconds, tracks every set with RPE, and learns your training pattern over time. Built for lifters who want serious data without spreadsheet babysitting.

RepFlows assembles a workout from a curated 800+ exercise database in seconds. • Track sets with RPE - Rate of Perceived Exertion (1–10) on every set, plotted over time so you can see when fatigue is creeping in before it stalls progress. • Log workouts your way - type, dictate, or pick from history.

RepFlows sits in the middle: enough data to make real decisions, simple enough to use mid-set. AI generation removes the "what should I train today" friction, RPE tracking catches overreach early, and the exercise database means you're never stuck with a movement you can't perform. PRIVACY Your workouts and measurements stay yours. We don't sell data, run third-party ad networks, or train external models on your training history. Sign in with Apple, Google, or email — your choice. CROSS-PLATFORM RepFlow runs on iPhone and on the web at repflows.ai. Pro subscriptions purchased on iOS unlock both. Your data syncs in real time.
