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. WHAT YOU CAN DO • Generate workouts with AI - pick your split, equipment, and target duration. 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. Build-then-start flow lets you preview the full workout, swap exercises, and edit before you start lifting. • Browse 800+ exercises — full anatomy diagrams, primary/secondary muscle targeting, equipment filters, and form notes. Favorite the ones you actually use. • Track personal records — automatic PR detection on weight × reps, with progression charts per exercise. • See body progress — measurements, body weight, photo timeline, all in one place. PRO FEATURES Pro unlocks the full app: unlimited AI workout generation, advanced RPE trend analysis, exercise favorites, body measurement charts, and priority access to new features. • Free: 5 AI workouts per month, basic logging, exercise browser • Pro Monthly: $4.99/mo • Pro Annual: $49.99/yr (save 17%) — includes 7-day free trial • All plans auto-renew. Cancel anytime in Settings. WHY RepFlows Most fitness apps either overwhelm you with charts or oversimplify into another rep counter. 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.
