Compound is a workout app with exactly one workout in it. NO MORE BOOKKEEPING Compound runs on double progression, a tried-and-true method for getting stronger. We just handle the bookkeeping. Hit your target reps, and the app bumps the target up for next time. Hit the top of the rep range? The weight goes up (5 lbs for big lifts, 2.5 lbs for accessories) and your reps reset. If you miss a set, just long-press to log what you actually did, and the app holds the weight steady until you're ready. No spreadsheets, no thinking. If you want a slower climb, you can tell the app to require up to five successful sessions before it forces a weight jump. MORE THAN JUST MOVING WEIGHT Every workout starts with an actual warm-up: three minutes of timed cardio, dynamic movements, and ramp-up sets calculated directly from your first working weight. Rest timers kick in automatically between sets. Ten minutes of guided mobility wraps up the day. You can tweak or turn off any of this, but the defaults are designed to give you a complete, balanced program. TRACKS LIKE REAL LIFE Not every exercise fits perfectly into a generic "reps and weight" counter. Tap to log your squats. Run the built-in stopwatch for dead hangs and let it save your PR. Use the countdown for planks. Every exercise is tracked exactly the way you actually do it. LEAVE YOUR PHONE IN YOUR POCKET The Apple Watch app mirrors your session in real time. Log sets, skip rests, and adjust the weight on the bar right from your wrist. Your phone and watch stay perfectly synced, and everything gets sent straight to Apple Health, complete with your heart rate and active calories. YOURS, PRIVATELY No account. No sign-up. Nothing is uploaded to a server that reads your training. Your history is stored on your device, full stop, and you can export the whole of it as a file at any time, subscribed or not. Start by entering the weights you lift today, or start everything at zero and let the progression build. Either way, the next session is always ready. SUBSCRIPTION Compound Standard unlocks the whole app and comes in two terms, monthly and annual, both opening with a 14-day free trial. Prices are shown in your own currency on the subscription screen inside the app before anything is charged. Payment is charged to your Apple Account at confirmation. It renews automatically unless auto-renew is switched off at least 24 hours before the current period ends, and can be managed or cancelled any time in Settings › Apple Account › Subscriptions.
