DeskWalker logs calories, steps, and distance for every under-desk treadmill session — using the same science-backed formulas used in academic research.

Features
Built specifically for under-desk treadmills — not generic step counters. DeskWalker knows that your wrists barely move while you type, so it derives steps and distance from speed instead of the accelerometer.
Accurate calorie tracking
Uses the SMU treadmill equation, Keytel heart-rate formula, and Apple Watch VO₂max for the most accurate estimate available.
Steps from speed
Apple Watch under-counts walking pad steps by 60–80%. DeskWalker derives steps from belt speed and your height instead.
Apple Health sync
Reads heart rate and VO₂max from Apple Health to improve calorie accuracy. No manual input needed if you wear an Apple Watch.
Afterburn (EPOC)
Automatically reads post-session active energy from Apple Health — the extra calories burned while your body recovers.
Badges & streaks
Earn milestone badges for First Steps, Desk Warrior, Century, Marathon Desk, and Consistency. Track your streak day by day.
Private by design
Every byte of your data stays on your iPhone. No account, no cloud, no analytics. Zero data leaves your device.
How it works
No Bluetooth pairing, no account setup, no manual configuration. Just open the app and walk.
Set your speed
Enter the belt speed shown on your walking pad display. DeskWalker remembers it for next time.
Start the session
Tap Start — the timer runs in the background while you work. Live Activity shows progress on your Lock Screen (Pro).
Stop & review
Tap Stop and get a full summary: calories, EPOC, steps, distance, average heart rate and the method used.
Recalibrates automatically
Health data from your watch often arrives minutes later. DeskWalker silently re-calculates recent sessions in the background.
Science-backed formulas — Calorie calculations use the SMU treadmill oxygen-cost equation (ACSM 2021), Keytel et al. heart-rate regression (J Sports Sci, 2005), and a MET fallback (Ainsworth Compendium, 2011). Steps use the sex-neutral stride constant from DeVita & Hortobágyi (J Appl Physiol, 2000).
DeskWalker has no backend, no user accounts, and no analytics SDK. All session history is stored locally using encrypted on-device storage. There is nothing to breach because there is nothing to collect.
Two subscription options (monthly and yearly) or a one-time lifetime unlock — your choice. Exact prices and regional availability in the App Store.
Subscriptions renew until cancelled; lifetime is a one-time purchase · Manage or cancel in App Store account settings
