On Lifting is a fast, private workout log: no account, no ads, no tracking. Most sets take one tap to log, and you can follow your progress in depth. Key Features • Private by default. Your data stays on your device and in your own backups. Logging works fully offline. • Designed for speed: smart defaults and a dedicated keyboard keep logging quick. • Family Sharing included at no extra cost. Free to download, no account needed. Your first 10 workouts are free, and imported workouts don't count. Still not sure On Lifting is right for you? Keep going with a free trial: 3 months on the yearly plan or 1 month on the monthly. Cancel anytime. One subscription covers your family through Family Sharing, and your history, charts and exports are always available whether you subscribe or not. Here's what you get: Workouts & Routines • Find a program for your level and schedule in the program library. Each one explains what it's for, how it works and how to progress. • More than 270 exercises with short, to-the-point how-to videos. • Create your own exercises to complement the built-in library. • Set up routines and programs, and reorganize them as your training evolves. • Group exercises into supersets in your routines and workouts. • Configure different set types: warm-up, drop sets, to-failure, work sets. • Define targets for reps, weight, duration, or intensity per set (great for progressive overload). • Supports Reps in Reserve (RIR) and Rate of Perceived Exertion (RPE) for tracking intensity. • Flexible rest timers that automatically track rest between sets. Customize by exercise, routine, or both. • Add notes to exercises, routines, and workouts. Track form cues, machine settings, or how a session felt. • Supports imperial (lb) and metric (kg) units. Progression & Insights • Visualize gains with charts that show trends in volume, strength, one rep max, and more. • Pin your core lifts and track their progress over time with detailed charts and personal records. • See which muscles your training covers with a body map and a 12-week heat map. • Set a weekly workout goal and build a streak. • Track progression at the program level: workouts, volume, personal records, and consistency. • Log body measurements like weight and body fat percentage with trend charts. • Browse your workout history with a full calendar. Zoom from month to year to multi-year for a bird's-eye view of your training. Apple Ecosystem • Apple Watch app mirrors your workout, showing the upcoming exercise, current set target, previous set data, rest time, and more. • Follow your workout on the Lock Screen and in the Dynamic Island. • Home Screen and Lock Screen widgets for your streak, workout calendar, heat map and pinned lifts. • Integrates with Apple Health on your iPhone and Apple Watch, including body measurements. Your data, your rules • Privacy first. I don't collect or store any of your data. • Export your workouts to CSV anytime. • Import your history from other popular apps. Imported workouts don't count toward your free limit. • Daily backups to your iCloud Drive or iPhone, easy to restore. This is just the beginning I am a solo self-funded developer with low overhead — no big company or investors here. I am making something I love and use every day, built to respect your privacy. I hope to provide a lot of value, far greater than what I charge, supported by a like-minded audience. As the primary user, I have a long roadmap ahead, and I am committed to keeping the app affordable, clean, fast, and privacy-focused as it grows. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
