Strontr

Strength & Cardio Tracker

Free · In‑App Purchases · Designed for iPad

Ready for iPhone Duo on day one. A generous free account, 2 weeks of PRO free, a card for every new PR, and an Evolve Plan that adapts your lifting and cardio weekly. Strontr is the workout app built for lifters, runners, and anyone who wants structured training without the spreadsheet. Train heavier. Run further. Own the streak. Start free. The free account is extremely generous. PLAN YOUR TRAINING • Build your own splits — as many plans and days as you like • Pin days to weekdays, or keep them flexible with “Any day” • Merge two days into one session when time is short • Duplicate a whole plan to try a variation without losing the original LOG FAST • Log weight, reps and notes in a couple of taps • Automatic rest timer between sets • Supersets, timed holds and single-side exercises, logged per side • Your plan remembers the weight, reps and rest you used last • Full exercise history and automatic personal records EVOLVE PLAN · PRO Your Evolve Plan adapts every week to what you actually lifted. Hit your targets and it adds reps, then weight. Miss them and it holds or eases off. Stall for a few weeks and it schedules a lighter week so you come back stronger. Every change comes with its reason. CARDIO EVOLVE PLAN · PRO Runs, walks and hikes with GPS distance, pace, splits and voice cues. Your Cardio Evolve Plan builds each week's sessions — from easy walks to intervals to long runs — and adjusts to how your last weeks went. STATS THAT MATTER • Weekly volume, streaks, muscle focus and a training calendar • Body weight and body fat tracking, synced with Apple Health ON YOUR WRIST • An Apple Watch app to follow your workout and log sets from your wrist BUILT FOR THE GYM FLOOR • Works offline and syncs when you're back online • No ads. No social feed. • Use the app in your own language AN EXTREMELY GENEROUS FREE ACCOUNT Strontr's free account is extremely generous: the exercise library, unlimited plans of your own, your full workout history and the calendar are free forever, with no limits and no ads. STRONTR PRO Evolve Plan, Cardio Evolve Plan, advanced analytics and more. Start with a 2-week free trial. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID settings.

Try Strontr PRO free for 2 weeks. • New: Trainer Mode, free for trainers. Trainers send gym and cardio plans to their clients and follow their workouts and runs. • Clients get a notification whenever their trainer sends, updates or stops a plan. • While you train with a trainer, your Evolve Plan pauses and folds away. Resume it any time. • Evolve Plan day names now show in your language. • Setup screens fit iPhone Duo's folded screen better. • Smoother, more reliable sync.
