RepXP
RepXP
Stop guessing your next weight.
RepXP automatically increases your weight or reps every workout based on your performance.
Just show up and lift.
Free download. Includes Apple Watch app.
RepXP is not a workout planner.
It's a progression engine.
Log your sets.
RepXP handles progressive overload automatically.
Log your sets in seconds. RepXP plans the next weight, so you keep progressing without plateaus.
Never plateau again. RepXP calculates your next weight and reps based on your performance history. Stuck for too long? Smart deload automatically reduces your weight to help you break through.
Auto-start rest timer with Live Activity support keeps you focused on lifting, not your phone.
Automatic personal record tracking for weight, reps, and volume. Get notified when you're about to break a record.
Use your own gear. Configure your exact plates, dumbbells, and machines. Get accurate plate loading and weight suggestions that match what you actually have.
Log workouts without internet. Everything syncs across iPhone, iPad, and Apple Watch when you're back online.
Sync weight, body fat, and workout data with Apple Health, so your lifting sits alongside everything else you track.
Train by feel, backed by data. Rate how hard each set, exercise, or session felt with a quick RPE or RIR slider, or turn the prompts off entirely. Your effort powers recovery and stress trends, and on Pro it nudges your progression, easing off after brutal sessions and pushing when a lift felt easy. Free to log and view.

RepXP is privacy-first. Your workouts, weights, and health data never leave your device. There's no account, and we run no servers that store your personal data.
Exercises, weights, reps, and HealthKit data are never collected or transmitted. iCloud sync goes through your personal Apple account, which we can't access.
No name, email, phone number, or location. Nothing we collect can identify you, and we never sell or share data with third parties.
The only data that leaves your phone is anonymous crash reports and usage patterns so we can fix bugs, never your workout details.
1RM estimates, plate math, progress photos, and body measurements in one place.
Calculate one-rep max using proven formulas and watch your estimated maxes climb over time.
Visualize volume, frequency, and strength trends over time to identify what's working.
Load the bar instantly. Visual plate calculator shows exactly which plates to use, no mental math required.
Privacy-locked photo tracking with side-by-side comparisons over time.
Monitor chest, arms, waist, and leg measurements to see results beyond the scale.
Customize for your gym. Configure available barbells, dumbbells, and plates for accurate weight suggestions.
Leave your phone in the locker. Full Apple Watch app with everything you need to log workouts from your wrist.
RepXP includes gamification features like XP, levels, and achievement badges. Completely optional. Use them if they motivate you, or hide them entirely if they don't. Change your mind later? Switch them back on and nothing is lost: your XP, levels, and badges stay up to date behind the scenes.
