GRX: Offline Workout Tracker

100% offline. 100% private. Your data, yours forever.

Your workouts do not need the internet. Your history does not need to live on a company's servers. And you do not need a subscription to keep using what is already yours.

GRX is your workout planner, gym log and training journal. Build routines, record weights, sets and reps, and keep a lifetime of workout history.

Pay once. Yours forever. No account. No subscription. No ads.

TRAIN WITHOUT THE INTERNET

At the gym, at home or wherever you are: build workouts, follow your routine, log each exercise and review your history offline.

GRX works without GRX APIs, servers or an online account. Your training stays with you, on your device.

PRIVACY COMES FIRST

Your data belongs to you. Your workout history stays on your device without needing to be sent to GRX servers.

No registration, public profile or social feed. Just you, your workouts and your progress.

BUILD A ROUTINE OR LET THE ALGORITHM HELP

Create your own workouts, choose exercises and organize your routine your way.

Want a starting point? The built-in workout generation algorithm uses your preferences and the exercise catalog to create a routine. Everything runs in the app, without the internet or external AI services.

Adjust your routine whenever you want. It is your workout.

LOG EVERY SET

Record weights, sets and reps for every exercise. Track what you actually did and check those numbers next time.

Add notes about technique, machine settings, exercise variations and anything you want to remember for your next session.

A LIFETIME OF WORKOUT HISTORY

Every workout becomes part of your story. Review past sessions, see what you lifted and follow changes in your weights and reps over time.

Your history stays available without monthly fees or a subscription to unlock your own records.

SEE YOUR PROGRESS

View your workouts and progress on your dashboard. Compare your records over time and use your history to plan what comes next.

YOUR ROUTINE ON APPLE WATCH

Take your routine to your wrist. View your workout plan and follow your exercises on Apple Watch as you train.

ICLOUD WITH YOUR OWN ACCOUNT

Use optional iCloud sync to keep your records across compatible devices through your own Apple account.

It is your choice. Your workouts keep working offline, with your data on your device and no reliance on GRX servers.

EXPORT YOUR DATA ANYTIME

Your data is yours to take with you.

With one button in settings, export your workout history, weights, sets and reps. Keep a copy, run your own analysis or use your records in other compatible apps.

No permission to request. No payment to access what is yours. No lock-in to GRX.

ONE PURCHASE. YOURS FOREVER.

No monthly fees. No subscription. No ads. No account. No reliance on GRX APIs or servers to train.

Your workouts. Your history. Your data. Offline, private and yours forever.
