How RepXP Is Different

RepXP is not a workout planner.
It's a progression engine.

Log your sets.
RepXP handles progressive overload automatically.

Features

Built for Lifters Who Train Smart

Frictionless logging meets intelligent progression. Track workouts in seconds and progress consistently without plateaus.

Auto-Progression System

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.

Effortless Rest Timing

Stay in the zone. Auto-start rest timer with Live Activity support keeps you focused on lifting, not your phone.

Instant PR Detection

Celebrate every win. Automatic personal record tracking for weight, reps, and volume. Get notified when you're about to break a record.

Custom Equipment Support

Use your own gear. Configure your exact plates, dumbbells, and machines. Get accurate plate loading and weight suggestions that match what you actually have.

Offline-First with iCloud Sync

Works anywhere. Log workouts without internet, sync seamlessly across iPhone, iPad, and Apple Watch.

Apple Health Integration

Complete fitness picture. Sync weight, body fat, and workout data with Apple Health for comprehensive tracking.

Effort Tracking (RPE / RIR)

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.

Privacy

Your Data Stays on Your Phone

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.

Workout & Health Data Stays On Device

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 Account, No Tracking

No name, email, phone number, or location. Nothing we collect can identify you, and we never sell or share data with third parties.

Anonymous Diagnostics Only

The only data that leaves your phone is anonymous crash reports and usage patterns so we can fix bugs, never your workout details.

Tools

1RM estimator, progression tracking, and analytics to measure what actually matters.

1RM Estimator & Progression

Analytics & Charts

See your progress clearly. Visualize volume, frequency, and strength trends over time to identify what's working.

Plate Calculator

Progress Photos

Document your transformation. Privacy-locked photo tracking with side-by-side comparisons over time.

Body Measurements
