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.

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/

A workout doesn't have to be a job, a personality, or a contest. When you were a kid, it was just fun: you saw a log in the woods and wondered if you could lift it, grabbed the dog and went for a hike, or raced to the park. That's what STRONK is built on. It doesn't care whether you lift 100 pounds or 1,000; walk a mile or ruck a marathon. You showed up, probably had fun, and hopefully did something worth telling your friends about. That's it. $4.99. ONCE. The going rate for a ruck tracker is $4.99 a month. This is $4.99, one time. Not a month. Not a year. Not ever again. Try everything free for 14 days; if you're in, it's one small payment, shareable with your family, yours forever. That's not a launch price. That's the point. (The tools underneath are real, though. Aggressively real.) LIFT Log sets fast, from your phone or your wrist, in type you can read from the bench without your glasses. Your last session sits next to this one, so you always know what you're trying to beat. No judgment when you don't. Supersets, because your time matters. Rest timers set to YOUR rest — 30 seconds or 5 minutes. STRONK doesn't lecture. RUCK Your other app calls a 35-lb ruck a walk. STRONK counts your body weight PLUS the weight on your back — and the formula is written out in plain English inside the app, so you can check our work. GPS routes, per-mile splits, elevation and heart rate, incline-aware treadmill rucks, and the weather you suffered through, on the record ("SWAMP MODE" is a real designation, earned). RUCK BUDDIES Tag which dogs came along (you know they're coming). They carried nothing. They get full credit anyway — name, photo, and all, right on the summary. Their pictures never leave your phone. RECEIPTS Every workout ends in a stat worth sharing: "1.5 WOOLLY MAMMOTHS." "741 CORGIS." "6.7 OSCAR STATUETTES, CARRIED A MILE." Lifetime totals that only go up. A calendar with no streaks and no guilt — just proof you showed up. History logs every exercise, set, rep, and mile (or kilometer) for posterity. NOTHING GETS LOST A finished workout is finished. It survives force-quits, dead batteries, and fat fingers. A save that fails says so instead of shrugging. The number on your wrist is the number in your history. Losing a session you actually did is the worst thing a tracker can do to you, and we build like we believe that. WHAT STRONK WILL NEVER DO No subscriptions. No ads. No streaks. No pep talks. No sweaty models. No fire emojis. APPLE STUFF, DONE PROPERLY Full Apple Watch app. Live Activities. HealthKit in and out — workouts, calories, routes, heart rate. Weather via WeatherKit. Photos picked privately, stored on-device. VoiceOver throughout. No account. No tracking. Your data is yours. And if you find the beta toggle in Settings... that's DASH. Race ya to the mailbox. Built in Minnesota by one guy, his wife, and two supervisory dogs. The feedback email is in Settings — it goes to an actual human, and fixes ship faster than you'd think.
