Stop guessing your next weight, and stop trusting apps that guess it for you. RepXP tells you what to lift next, shows you why, and only suggests weights your gym actually has. • Every change explains itself: see the new weight or reps and the reason under it before you start. • Weights your gym actually has: set up your plates, dumbbells and machines, and every increase lands on a load you can make. • A safe way back after a break: time off lowers the weights, then builds them back up to where you were. No account. No ads. No paywall at sign-up. Logging is free, and eligible new subscribers can try Pro free for a month. NEW IN 4.0 Every screen, from your workout to the Apple Watch app, has been rebuilt in a bolder design that is easy to read mid-set. Progress photos now sync through iCloud, import from your photo library with their original dates, and turn into a before and after image you can share. PROGRESSION YOU CAN TRUST Define your progression once. RepXP adds reps within your range, moves the weight when you are ready, reacts to the effort you log, and suggests a deload when progress stalls. Each change is shown with its reason, and any change can be reverted with one tap. A ROUTINE BEFORE YOUR FIRST SESSION Answer a few questions about your training days, how long you have, your goal and your equipment, and RepXP writes the routine, with a starting weight on every exercise. Every number is one tap from being changed. FAST WORKOUT LOGGING • Confirm sets with one tap • Track RPE or RIR by set, exercise, or session • Automatic rest timers with Live Activities • Plate calculator for bars, machines, weight stacks and dumbbells • Weight, rep, volume and estimated 1RM records detected as you lift TRAIN PHONE-FREE ON APPLE WATCH Start and finish complete workouts from your wrist. Log sets, change reps or weight, see the next set's weight and reps while you rest, and feel a tap when rest is over. During cardio, see live heart rate and your current zone.
