RuckDayEvery day is ruck day.
Track distance, pace and pack weight, with calorie estimates that account for the load on your back and the hills you climb.
We'll email you when the beta opens and at launch. Nothing else.
Pack weight first
Set your load before you go. Every ruck records weight, distance and load × distance, so you can see your total work over time.
Hills and stairs count
Calorie estimates use the Pandolf load-carriage equation, which accounts for your pack weight, the climb and the terrain.
Apple Watch, standalone
Leave your phone at home. The watch records heart rate and distance, saves the ruck to Apple Health and syncs it to your iPhone.
Private by default
Your rucks stay on your devices and in Apple Health. No account, no tracking.
