Volt turns your iPhone (and Apple Watch) into a smart control panel for your Bluetooth treadmill. Connect once, then control speed and incline, watch your live stats, and let Volt automatically adjust your pace for you — all while every workout is saved straight to Apple Health. Works with any treadmill that supports the Bluetooth FTMS (Fitness Machine Service) standard. LIVE TREADMILL CONTROL - Start, pause, resume, and stop your treadmill directly from your phone - Adjust speed and incline in real time, no need to touch the console - See live speed, distance, incline, elapsed time, and calories at a glance - Safety-first pairing: nearby treadmills are ranked by signal strength, and Volt warns you if a machine looks like it's already in use before you connect SMART WORKOUT MODES - Free Run — full manual control, your pace, your rules - Heart Rate Cruise Control — set a target heart rate and Volt automatically raises or lowers treadmill speed to keep you in your zone - HIIT Intervals — automated sprint/walk intervals with treadmill speed changes handled for you, so you can focus on the effort APPLE WATCH COMPANION - Mirrors your live speed, distance, incline, and heart rate to your wrist - Start and stop workouts from either device — they stay in sync - Optional haptic feedback for pace changes and interval transitions - Built for Always-On Display, so your stats stay sharp and readable without draining your battery APPLE HEALTH INTEGRATION - Every completed workout is saved to Health automatically — duration, distance, calories, and heart rate - Works whether or not you're wearing your Apple Watch: Volt saves the workout from your phone if your watch isn't paired for the session - Detailed per-second telemetry means your workout history shows real speed and heart-rate charts, not just a summary DYNAMIC ISLAND & LIVE ACTIVITY - Track your run from your iPhone's Lock Screen or the Dynamic Island without opening the app - Live speed, distance, and elapsed time, updated as you move WORKOUT HISTORY - Every past workout in one place, with distance, duration, calories, and average pace - Tap into any workout for a full speed, incline, and heart-rate breakdown over time MADE FOR RUNNERS AND WALKERS - Personalize calorie estimates with your own body weight - Available in English and Hungarian - A clean, distraction-free dashboard designed to be read at a glance, whether you're sprinting or walking the dog on your $200 basement treadmill Volt doesn't try to be a full fitness platform — it does one thing well: make your Bluetooth treadmill smarter, safer to control, and fully connected to the Health app you already use. ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Volt Premium | $6.99 | per year | ## Version history (last 5 releases) ### 0.9 — 2026-09-17 • New: add a Volt widget to your Home Screen — a small one for one-tap workout start, a medium one showing your last run plus this week's or month's totals • New: add a Volt complication to your Apple Watch face showing this week's distance, time, and workout count • Custom workout and mode rows have been redesigned — preview, share, edit, and delete are now always available, even when the row itself can't be selected • Heart-rate zones are now personalized to your age — add your age in Settings › Profile, and your Fat Burn zone, Heart-Rate Cruise Control, and History's zone chart all use the same, more accurate range instead of one-size-fits-all numbers • Cool-Down now has a Constant style too, alongside the existing gradual Descending ramp — the same choice Warm-Up already had • Custom Workout heart-rate segments now show your live target range and a +/- stepper to adjust it mid-run, the same controls as Heart-Rate Cruise Control • New "extend or finish" toggle on the Dashboard during a Custom Workout — change your mind mid-run about whether the plan finishes itself at the end or keeps going • Reordering segments in the Custom Workout builder is easier and more precise — dedicated up/down buttons instead of drag-and-drop • The app now visually rotates to stay upright even when your phone is upside down • If your treadmill's Bluetooth connection drops mid-run, Volt now tries to reconnect automatically — resume right where you left off, or save what you've recorded so far, instead of losing the workout • Fixed: workouts started without requiring the Apple Watch no longer get paused waiting for one that isn't there • Improved compatibility with treadmills whose speed/incline commands were being silently ignored • The Home screen Start button now shows a spinner instead of looking frozen while your workout gets going • The changelog's "Got it" button now stays put at the bottom instead of making you scroll to find it ### 0.8 — 2026-09-14 • Choose your units — switch the whole app between metric (km, km/h) and imperial (mi, mph);
