Rucking – The Official Rucking Calculator App

Hey everyone, bear with me — this is my first app on the Play Store.
I never set out to make an app. I just got tired of watching my smartwatch undercount my workouts. I’ve been rucking for years — walking with weight to burn fat, build strength, and fix my posture — and there still isn’t a button that says Start Ruck.

So I built this.

Rucking Pro is the first simple, ad-free calculator app designed specifically for ruckers. It helps you estimate calories burned and plan your weight-loss goals more accurately than any walking or running tracker.

I’m Preston Shamblen, an ISSA and NCCPT-certified personal trainer, nutritionist, and strength coach. I lost 90 pounds through rucking, outdoor fitness, and consistency. Now I’m sharing the same tools that helped me stay motivated.

🧭 Features

Rucking Calorie Calculator: See how many calories you really burn based on body weight, ruck weight, distance, pace, and pack type.

Rucking Weight-Loss Calculator: Estimate how many days it’ll take to reach your goal — factoring in age, height, sex, calories eaten, and ruck routine.

Backpack vs. Vest Mode: Choose between back-loaded or evenly-weighted setups to get more accurate numbers.

Effort Levels: Adjust for terrain, incline, and pace — from casual walks to full-on uphill bracing.

Dark Mode & Offline Ready: Built for outdoor use — no login, no tracking, no ads.

💪 Why I Built It

Rucking burns 2–3× more calories than walking, but no major fitness platform accounts for the added load.
This app fixes that — so you don’t lose motivation seeing low numbers on your watch.

Future updates will add GPS tracking, distance logging, and Apple Health/Google Fit integration once testing is complete.
