Calories underestimated by up to 40%
Apple Watch and Strava don't know you're wearing 25 lbs. They track an ordinary walk.
Finally, an app that knows you're carrying weight.
Military-grade calorie accuracy. VO2Max protection. Built for weighted vests and rucking. Your effort has never been measured like this.
Loved by weighted training athletes, Ruckers, and weighted vest users all over the world
Your fitness app is lying to you.
Your VO2Max tanks when you train harder
Standard algorithms interpret your elevated heart rate + slow pace as poor fitness. They're wrong.
Your weighted vest is invisible to every major app
No weight input. No load physics. No credit for what you carry.
"We built RuckIt because we were tired of working harder and being told we were failing."
Carry More. Track Right.
The only load-aware fitness app built around physics, not guesswork.
YOUR WEIGHT COUNTS
40% more accurate. Because physics matters.
RuckIt uses the Pandolf Equation — the U.S. military's gold standard for load carriage — to calculate calories based on your body weight, vest weight, speed, grade, and terrain. Not an estimate. The actual math.
Apple Watch showed 245 cal. RuckIt showed 412 cal. Same walk. Real weight.
YOUR DATA IS PROTECTED
Train with weight. Keep your VO2Max intact.
Weighted workouts corrupt VO2Max on every major platform — Apple, Garmin, Strava. RuckIt categorizes your sessions separately, protecting the fitness trend you've worked years to build.
VO2 Shield™ — active during every weighted session
YOUR EFFORT IS CELEBRATED
One tap to start. Every pound counted.
Save your loadouts in Gear Locker — your 20 lb vest, your 35 lb pack. One tap starts tracking instantly. Your Apple Watch shows real-time calories, heart rate, and Zone 2 status at a glance.
Gear Locker — saved presets for instant tracking
The numbers don't lie.
