Description
Your fitness app is lying to you.
Strava says 320 calories. Apple Fitness says 310. Garmin says 305. You just carried a 40-pound pack for 4 miles — and every app on your phone treated it like a casual stroll.
Generic fitness apps were built for runners. They have no idea what a loaded ruck does to your body. They ignore your pack weight entirely. That means every calorie count, every effort score, every "great workout" notification you've ever received while rucking has been wrong.
Ruckaroo fixes that.
MEET YOUR RUCK SCORE
Ruckaroo is the only app that calculates your true calorie burn using the Pandolf equation — the same military-grade formula the US Army has used since 1977. It accounts for every variable that matters: your body weight, pack weight, pace, terrain, and elevation. The result is your Ruck Score — a 0 to 100 performance metric that finally reflects how hard you actually worked.
Same route. Same distance. 40-pound pack. That's 380 calories, not 320. Now you know.
TRACK WHAT ACTUALLY MATTERS
• Log every ruck: distance, time, pack weight, location, and terrain
• Get your Ruck Score after every session — a single number that captures your true effort
• See your real calorie burn, not a generic walking estimate
• Track monthly and lifetime stats to see your progress over time
• Apple Watch support — track from your wrist, hands-free
• Zone 2 heart rate tracking for fat-burning and cardiovascular optimization
EARN YOUR BADGES
Every ruck earns you something. Unlock badges for distance milestones, consistency streaks, weight thresholds, and personal records. From your first Trek badge to the Siege badge — there's always a next goal to chase. The badges keep you coming back when motivation runs low.
YOUR AI RUCK COACH
Ask anything. Your built-in AI coach knows your Ruck Score history, your pack weight trends, your terrain, and your goals — so the answers are specific to you, not generic fitness advice. Training for a GORUCK event? Wondering if your knees can handle heavier loads? It's the one coach that actually knows what you've been carrying.
BUILT FOR EVERYONE WHO CARRIES WEIGHT
Ruckaroo was built for the full spectrum of ruckers — not just the military crowd.
Military & Tactical Athletes: Train smarter for ruck marches, SFAS, Ranger School, or your next GORUCK event. Get the metrics that actually matter for weighted movement.
Hikers & Outdoor Enthusiasts: Turn your weighted hikes into trackable, measurable workouts. Stop guessing how hard you worked.
Women Who Walk: Rucking burns up to 2× more calories than regular walking with zero extra impact on your joints. If you're already walking, adding a loaded pack is the single highest-return change you can make — and Ruckaroo will show you exactly what it's worth.
Fitness Beginners: Low impact. High calorie burn. No gym required. Rucking is one of the most accessible forms of cardio that exists — and Ruckaroo makes it easy to start, track, and improve.
Weight Loss Seekers: Stop underestimating your workouts. Your pack weight changes everything. See your real numbers and stay motivated with accurate data.
Zone 2 Athletes: Optimize your weighted movement for fat burning and cardiovascular health with precise heart rate zone tracking.
