Repdex is a gym notebook that works the way training actually works: look something up, write down what you lifted, close the app. Twenty times a session, ten seconds at a time. Everything you log lives on the device. No account, no sign-up - the whole catalogue ships inside the app, so it works in a basement gym with no signal. 1324 EXERCISES, ALL OFFLINE Every exercise comes with an animation, a thumbnail, and step-by-step instructions in 10 languages. Filter by body part, equipment, or target muscle, or search all 1324 at once. BUILT TO BE USED MID-SET Weight and reps are editable right on the workout screen, with no second page to drill into. Tick a set and the rest timer rises on its own. Every figure is tabular, so the timer never shifts as it counts down. A DARK MODE MADE FOR THE GYM FLOOR Not a recolour. In the dark the readouts get larger and heavier, because dark mode is what you use when the phone is sitting on the rack an arm's length away. ROUTINES ALREADY WAITING Answer four questions on first launch and your split is there: push, pull, legs, upper, with sets and starting weights matched to how long you have been training. WHAT YOU TRACK Volume, duration, completed sets. An eight-week chart. Personal records per exercise. Consecutive weeks rather than consecutive days, because training is supposed to have rest days in it. FREE, ALWAYS All 1324 exercises. All 10 instruction languages. Unlimited workout logging. Your history is never locked, subscription or not. No weight tracking. No body fat. No calories. No meal plans. It is a training log. —————— Repdex Pro (auto-renewing subscription) A subscription unlocks unlimited routines, advanced stats, CSV data export and home-screen widgets: • Monthly plan — billed every 1 month • Yearly plan — billed every 1 year • Lifetime — a one-time purchase, not a subscription The yearly plan includes a 7-day free trial for new subscribers.
