Not a gym tracker. A muscle tracker.

Track every muscle.
Build every rep.

Most apps count reps. KasMaker tracks muscles. See what you've worked on an interactive body map, detect PRs, and get smart training insights.

Every exercise, mapped to muscle.

Bench press doesn't just mean "chest day." KasMaker knows it hits your chest, triceps, and front delts — and paints all three on your body map.

  • Primary muscles light up bright, secondary muscles dimmer
  • Tap any muscle for its stats and exercise recommendations
  • Set your own tracking window — 3 days, 10 days, your call
  • Fresh, recovering, or fatigued for every musclePRO

Fast enough to keep up with your set.

Reps and weight come pre-filled from last time, so you pick up where you left off. Add exercises all day — your log stays continuous instead of forcing you to start a new session.

  • 800+ exercises with instructions, filtered by your equipment
  • Rest timer auto-starts on a completed set, and waits out the whole round on supersets
  • Warm-up, drop set, and to-failure markers — warm-ups never inflate your PRs or your map
  • Plate calculator, warm-up ramps, and optional RPE/RIR effort tracking

Everything else, in detail.

What is per-muscle recovery readiness?

Every muscle gets a readiness state — fresh, recovering, or fatigued — based on your sets and that muscle's recovery window, so you know what's ready to train today. Rated sets sharpen the estimate. Recovery readiness is a KasMaker Pro feature.

Can I change how far back the muscle map looks?

Yes. Set your own tracking window — 3 days, 10 days, your call. Your muscle map, stats, and recovery all follow how you actually train, and the map fades in time with your window.

How much does KasMaker cost?

KasMaker is free to download and includes unlimited workout logging, unlimited routines, the muscle body map, PR detection, the rest timer, supersets, a plate calculator, a warm-up calculator with set types, RPE/RIR effort tracking, Apple Health sync, iCloud sync, and 800+ exercises. KasMaker Pro is an optional upgrade that unlocks per-muscle recovery readiness, progress charts, all training insights, and CSV export — $2.99 monthly, $19.99 yearly, or $49.99 once for lifetime. There are no ads and no third-party tracking.

Does KasMaker sync across devices?

Yes. KasMaker uses iCloud to sync your workout data across all your Apple devices automatically and follow you to a new phone — no account to create. It also works fully offline if you'd rather stay local. Finished workouts can optionally be saved to Apple Health so your lifting counts toward your activity.

Does KasMaker collect my data?

No. Your data stays on your device and syncs securely via iCloud. Nothing is collected or shared with third parties, and there is no tracking or analytics.

Can I export my workout data?

Yes. You can export all your workout history as a CSV file from the Settings screen. CSV export is a KasMaker Pro feature.

Does KasMaker have a light theme?

Yes. KasMaker ships in dark by default — built for the gym floor — and you can switch to light or follow your system appearance from Settings. Six accent colors are available too.

What iOS version is required?

KasMaker requires iOS 18 or later.

What does "Kas" mean?

Kas means "muscle" in Turkish. KasMaker = muscle maker.

No account required. Your data stays yours.
