Not a gym tracker. A muscle tracker.

Everything you need.
Nothing you don't.

See your muscles

Interactive Body Map

Every exercise is mapped to primary and secondary muscles — bench press lights up your chest, triceps, and front delts. Tap any muscle for stats and exercise recommendations.

Muscle Recovery

Every muscle gets a readiness state — fresh, recovering, or fatigued — based on your sets and each muscle's recovery window. Know what's ready to train today.

Customizable Tracking Window

Set how far back your muscle map and stats look — 3 days, 10 days, your call. Tracking and recovery both follow how you actually train.

Log without friction

800+ Exercises

Curated database with instructions and images. Filtered by your equipment and muscle group.

Routines from Real History

Build a routine from a workout you actually did, not a blank template. Edit freely mid-session — your routine and your session stay separate.

Smart Rest Timer

Auto-starts when you complete a set. Tap to adjust duration. Stays out of your way.

Supersets

Link exercises to run back to back. Grouped exercises are badged in your log, and the rest timer waits for the end of the round — not the middle of it.

Apple Health Sync

Optionally save every finished workout to Apple Health, so your lifting counts toward your activity. Your data stays yours.

iCloud Sync & Backup

Your workouts sync across your Apple devices and follow you to a new phone — no account to create. Works fully offline too if you'd rather stay local.

For serious lifters

Set Types & Warm-up Calculator

Mark sets as warm-up, drop set, or to failure — right from the set number. The warm-up calculator ramps you from the empty bar to your working weight, and warm-ups never inflate your PRs, muscle map, or recovery.

RPE & RIR Effort Tracking

Rate how hard each set felt right after the checkmark — RPE or reps in reserve, your choice. Rated sets sharpen your muscle recovery estimates. Off by default, zero clutter.

Plate Calculator

Tap Plates on any barbell exercise and see exactly what to load per side — pick your bar, get the breakdown. No more gym math between sets.

Track your progress

PR Detection

Personal records are detected automatically and celebrated in real time. Never miss a milestone.

Progress Charts

Track strength gains over time with weight and estimated 1RM charts for every exercise.

Training Insights

Push/pull balance, recovery tracking, volume analysis, and progressive overload suggestions.

Your muscles.
Always visible.

See Your Map

Your body map lights up — primary muscles bright, secondary muscles dimmer. Set your own recovery window so the map fades in time with how you actually train.

Built different.
