RepThemes is a fast, private workout tracker and gym log for lifters who want to log sets, hit PRs, and actually see progress - with zero ads, no account, and your workout data never leaving your phone. It's also a workout tracker you can completely reskin with collectible themes.

WORKOUT TRACKER BUILT FOR THE GYM
Log weight, reps, sets, distance, and time with a clean, tap-friendly set logger. Build a workout on the fly or start from a template. Supersets, drop sets, rest-pause, warm-up sets, and unilateral (per-arm / per-leg) tracking are all first-class - whether you train strength, hypertrophy, powerlifting, bodybuilding, calisthenics, or cardio.

REST TIMER THAT KEEPS YOU MOVING
Automatic between-set and between-exercise rest timers with goal-based defaults, a full-screen alert, and one-tap adjustments. Optional hydration reminders keep you on pace during long sessions.

TRACK PRS AND REAL PROGRESS
Personal records (PRs) are detected automatically. History and Insights turn your gym log into real analytics: estimated 1-rep max and progression per lift, stalled lifts, biggest movers, weekly sets per muscle, push/pull and upper/lower balance, consistency streaks, and body-measurement trends.

BODY MAP + 330+ EXERCISE LIBRARY
Explore an anatomical body map to see which muscles you've trained, then tap a muscle to filter exercises. The built-in library covers a full commercial-gym floor - machines, cables, free weights, Olympic lifts, carries, and cardio - each with form cues. You can easily add new exercises without interrupting your workout.

29 COLLECTIBLE THEMES
This is what makes RepThemes different. Themes don't just recolor the app - each one fully reskins it: colors, fonts, icons, card shapes, backgrounds, and emblems. Find a look that matches your training vibe, from clean and minimalist to bold and heroic.

PRIVATE BY DESIGN - NO ADS, NO ACCOUNT
RepThemes is local-first. There's no sign-up and no login, and your workouts, measurements, and records are stored only on your device. Nothing is uploaded, tracked, or sold. Optional purchases are processed by Google Play and RevenueCat. No analytics SDKs. No ads. Ever. Export a full backup anytime and keep it wherever you like, or share a progress report with your own trainer through your phone's share sheet - you stay in control.

It's off by default, RepThemes only writes data and never reads it, and you can switch it off anytime. See our privacy policy for details on storage, retention and deletion.

RepThemes Pro (optional subscription) unlocks every theme; the workout tracker itself is free. Subscriptions are billed through Google Play and renew automatically until cancelled - manage or cancel anytime.
