Every step priced for the weight you carry.

Fly the ruck back in 3D.

Every ruck replays as a pitched flyover on real terrain, with distance, time and heart rate ticking along and the elevation profile underneath. It stops at the photos you took and exports as a vertical video for a story.

• Photos from your library pinned on the route where you took them, even with Camera location off
• Share cards with the route, your best three photos and the numbers

The route, painted by effort.

Each map colors itself by heart-rate zone, pace, grade or elevation. Splits carry heart rate and grade, personal bests are kept by load class, and a weekly load-mile trend shows the real training volume, because a mile at 45 lb isn't a mile at 20.

• Five heart-rate zones by max, reserve or your own numbers, live on the phone and wrist
• Grade-adjusted pace, cadence and step length

Pack the right water.

Before you step off, FueledRuck estimates your sweat rate from the load, the pace and the weather, and tells you what to carry. On the ruck, drink and carb cues arrive on your wrist and in your ear. At the finish, it says what you lost and what to put back.

• Grounded in ACSM fluid and carbohydrate guidance
• One tap logs each drink, so the refuel math is yours, not a guess

Someone should know.

Set a back-by time and FueledRuck checks in with you. Share a live link that anyone can open in a browser, no app needed: route so far, distance, time and check-in time. It turns red if you're overdue and deletes itself a day later.

• Add 30 minutes or mark yourself safe right from the notification
• Text your location to your check-in contact in one tap

Plans that bend to your log.

Pick a standard or an event and FueledRuck builds the weeks to get there. It raises work no more than ten percent a week, steps back every fourth week, and repeats a week when life gets in the way. A ten-second check-in after each ruck (effort, shoulders, feet, blisters) tunes the next one.

• Ranger 12-miler, British CFT, Norwegian Foot March, the FueledRuck ladder, and events on your calendar
• A live ahead-or-behind clock on the map while you ruck a standard

Leave the phone at home.

The Watch app rucks on its own: its own GPS and heart rate, load-aware energy in place of Apple's walking estimate, and the workout saved to Apple Health with the route. Turn the Digital Crown to set the load. When the phone is along, the Watch mirrors it instead, with pause and finish on the wrist.
