Are there fitness apps I can purchase that estimate rucking calories burned?
Yes. There are apps you can buy (or subscribe to) that claim to estimate rucking calories burned. But most “fitness apps” aren’t built for rucking—so they either:
- Track it as a normal walk/run (ignoring the load), or
- Paywall basic features behind a subscription, or
- Turn into an ad machine that cares more about marketing than rucking.
The better answer: use a ruck-specific tool that’s built around load-bearing training.
- The Rucking App is free (no paywall for basic features).
- It works offline (use it at the state park / trails with no signal).
- It supports backpack vs weighted vest (and in our model, backpack rucking is ~7% harder).
Built by Preston Shamblen — I lost 90 lbs rucking + training. The app is free because I want everyone to have it.
Watch: How to use the Rucking App
Quick walkthrough that shows how the calorie estimate works (and how to log backpack vs vest correctly).
Why rucking calorie estimates are tricky
Rucking is not “walking.” Your calorie burn is heavily influenced by:
- Your bodyweight
- The load you carry (ruck/vest weight)
- Pace (time per mile)
- Terrain (flat road vs hills vs trail)
- Carry type (backpack vs vest)
If an app doesn’t capture those inputs, it’s guessing.
Do you really need to “purchase” an app?
You can—if you want. Some apps lock features behind subscriptions because they’re paying for ads, affiliates, and app-store placement.
But you don’t need to pay just to estimate rucking calories. My app does it for free, and it works offline so you can use it anywhere.
Offline matters. A lot of rucking happens on trails, parks, and backroads where signal is weak. Offline tracking means you still get the estimate when you need it.
Backpack vs weighted vest: why the app asks
These aren’t the same workout.
Backpack rucking
- Harder feel: weight behind you increases stabilization demand.
- In our model: about ~7% harder than a vest at the same load/pace/distance.
- Best for: classic ruck style, longer carries, hydration + storage.
Weighted vest training
- More balanced: weight distributed front/back.
- Often easier to repeat for daily consistency.
- Best for: frequent rucks, hills, “throw it on and go.”
Gear that makes rucking easier (and more consistent)
If you’re going the weighted vest route, here’s a solid option:
Wolf Tactical Adjustable Weighted Vest
Balanced front/back load. Great for frequent training. #WolfTactical
