Marble is a private workout journal for fast logging, focused training, and clear progress. No account, ads, or third-party tracking.

WRITE IT YOUR WAY
Type or paste a workout in gym notation, bring in multi-day notes, or import a Hevy or Strong CSV. Scan handwritten workouts with on-device text recognition. When available, Apple Intelligence helps structure workout text on your device.

Review exercises, sets, weights, reps, dates, rest, and notes before saving. Weights without a unit follow your kg or lb preference. Save an unfinished review and return to it later. Log the same typed workout on another day while keeping same-day duplicate protection.

KEEP YOUR TRAINING MOVING
- Log weights, reps, distance, time, RPE, rest, and notes

SEE YOUR PROGRESS

- See your lifetime Top Exercises, with all-time best weights and the dates you lifted them
- Review Monthly Reports and Daily Highlights
- Explore muscle-group, rep-range, effort, supplement, and calendar views

CONNECT WITH iOS
Add a Weekly Goal widget, find exercises in Spotlight, and use Siri or Shortcuts to log sets and manage workout sessions. Open quick logging from supported Control Center, Lock Screen, or Action button controls.

OPTIONAL APPLE HEALTH INTEGRATION
Import Apple Health workouts, including workouts recorded by Apple Watch and Garmin apps that write to Health. Optionally export completed strength sessions to Apple Health. Health access is permission-based; you can use Marble without it.

KEEP CONTROL OF YOUR DATA
Your core training data is stored locally on your iPhone or iPad. Export and restore a portable JSON backup. Progress photos and videos stay on your device and are not included in those backup files. Marble has no account system or Marble-operated server.

Apple Intelligence features require a compatible device, supported language, and Apple Intelligence availability. Workout notation and structured file imports can be reviewed without Apple Intelligence.
