Onus: own your workout tracker. No subscriptions. No recurring fees. Pay once, lift forever. Tired of paying yearly just to log your sets? Onus is a complete strength training tracker built for lifters who are done renting their apps. Real Apple Watch Integration Track your workout from your iPhone, your Apple Watch, or both at once — fully synced in real time. Leave your phone in your bag and go watch-only. Leave the watch at home and use just your phone. Or run both together and switch seamlessly mid-workout. Even without your phone nearby, the Watch app starts, logs, and finishes a full workout on its own — including live heart rate and calories, a Now Playing music screen, and a watch face complication for one-tap access. Fast, focused, and lightweight No bloated media slowing things down. Onus is built to open instantly and stay out of your way — with quick links to trusted exercise tutorials whenever you need a refresher on form. A massive exercise library Browse 1,200+ built-in exercises with muscle group and equipment info, plus instructional lookups via YouTube and other trusted sources — or add your own custom exercises for movements or gym equipment that aren't in the catalog. Everything you need to train • Log sets, reps, and weight with a fast, intuitive interface, including live +/- adjusters and a custom keypad • Automatic personal record detection, celebrated with a trophy animation and marked everywhere your best lifts appear • Group exercises into supersets and circuits with round-by-round rest control • Built-in rest timers that keep counting even in the background • Build and reuse custom routines and multi-workout programs, or start from one of Onus's preloaded programs • Track your progress over time with clear history, weekly summaries, and trend graphs for 1RM, top set, volume, and max reps • Export your workout history to CSV, or share programs and workouts with training partners via file import/export • Automatic private iCloud backup, recoverable if you lose or replace your device Built to last, not to bill No subscriptions. No paywalls hiding basic features. No "premium tier" games. Pay once, and Onus is yours — including future iOS compatibility updates. Private by design Onus doesn't collect, transmit, or sell your data. No account, no ads, no tracking — everything lives on your device (and your own private iCloud, only if you choose to back up). If you've ever felt like your fitness app was working against your wallet more than your workout, Onus was built for you.
