VOLT is a beautiful strength-training tracker with one big idea: your body is the map. Tap a muscle on an interactive body map to see the exercises that train it, log your sets, and watch that muscle light up. No clutter, no account, no cloud — everything lives on your iPhone. TRAIN BY MUSCLE Tap any muscle on the front or back body map to jump straight to the right exercises. Recently trained muscles glow, so you always know what's fresh and what's neglected. EVERY EXERCISE, IN MOTION 100+ exercises, each with a clean animated demonstration so you know exactly how the movement should look before your first rep. LOG SETS THE HONEST WAY Start a workout, then tick off each set as you finish it. A rest timer, previous-set memory, supersets and a built-in plate calculator keep you moving instead of fiddling with your phone. PROGRESS YOU CAN FEEL Streaks, weekly volume charts, personal records and body-measurement tracking. An on-device coach spots plateaus and suggests what to train next — all computed on your phone. BUILD YOUR OWN ROUTINES Save reusable workouts — a set of exercises with your target sets and reps — then start one with a single tap on any day. Or clone a starter template (Push, Pull, Legs, Full Body). SHARE YOUR JOURNEY Turn a day, week, month or year of training into a gorgeous card built for Instagram and WhatsApp. Every share is proof of the work. PRIVATE BY DEFAULT VOLT has no servers and no account. Your workouts, measurements and records are stored only on your device and never sent anywhere. No analytics, no ads, no tracking. If you ever delete the app, your data goes with it — because there was never a copy anywhere else. VOLT is free. Download it, tap a muscle, and start training. Not medical advice. Consult a qualified professional before starting any exercise program and stop if you feel pain.
