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

• 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.

10.18.18 Aug 27
Strontr is completely free right now. Create your account before paid plans launch and you'll keep Lifetime PRO free for life.
This update fixes a bug with the timing of weekly Evolve Plan adaptations. It also improves Evolve Plan weight jumps and includes the following improvements:
• Your Evolve Plan now builds reps before it adds weight. The whole ladder climbs until you've clearly earned the jump, instead of moving up after one good session.
• Jumps are sized to the movement — smaller steps on isolation work, larger on the big compounds — so a lateral raise never gets the same increase as a squat.
• When the next weight on a machine or dumbbell rack would be too big a leap, your Evolve Plan holds you there and keeps adding reps rather than stalling you or overloading you.
• Your Evolve Plan reads the weights you've actually lifted to work out what your gym can really load, so it only ever prescribes a weight you can select.
• If a new weight turns out to be too much, your Evolve Plan puts you back and lets you earn it again — and gives you longer to earn it the second time.
• Repeating a workout builds volume without rushing your progression.
• Merging two days with "Combine Sets" now keeps every set from both.
• Delete a set or a whole exercise from Stats, not just from Calendar.
• Settings and plans back up more reliably.
Train heavier. Run further. Own the streak.
10.18.3 Aug 17
Strontr is completely free right now. Create your account before paid plans launch and you'll keep Lifetime PRO free for life.
This update fixes a Cardio Evolve bug where some finished sessions weren’t getting marked “done.”
This update also improves how your Evolve Plan decides when you're ready for more weight:
• Your Evolve Plan now builds reps before it adds weight. The whole ladder climbs until you've clearly earned the jump, instead of moving up after one good session.
• Jumps are sized to the movement — smaller steps on isolation work, larger on the big compounds — so a lateral raise never gets the same increase as a squat.
• When the next weight on a machine or dumbbell rack would be too big a leap, your Evolve Plan holds you there and keeps adding reps rather than stalling you or overloading you.
• Your Evolve Plan reads the weights you've actually lifted to work out what your gym can really load, so it only ever prescribes a weight you can select.
• If a new weight turns out to be too much, your Evolve Plan puts you back and lets you earn it again — and gives you longer to earn it the second time.
• Repeating a workout builds volume without rushing your progression.
• Merging two days with "Combine Sets" now keeps every set from both.
• Delete a set or a whole exercise from Stats, not just from Calendar.
• Settings and plans back up more reliably.

10.18.1 Aug 15
Strontr is completely free right now. Create your account before paid plans launch and you'll keep Lifetime PRO free for life.
This update makes Evolve Plans yours to shape, and teaches Strontr the gym you actually train in:
• Add any exercise to an Evolve Plan day and set it up per set — weight, reps, rest, and to-failure — plus a baseline your rep ladder returns to when the weight goes up.
• Rename Evolve Plan days to match how you think about your week.
• Set the real weight increment for any exercise and Evolve only ever prescribes weights your machine can actually load, giving you longer to earn the bigger jumps.
• Starting a new Evolve Plan keeps everything you've lifted: pick up at the weights you're already handling, or start completely fresh — your logged workouts stay either way.
• Cardio now runs to a target. Set a duration before you start or partway through; Strontr tells you when you hit it and keeps the session going.
• Mark a carried-over exercise done or clear it on one device and every device agrees.
• Adjust the start and end of any saved workout, or move it to another day.
Train heavier. Run further. Own the streak.
10.15.38 Aug 12
Strontr is completely free right now. Create your account before August 11 and you’ll keep Lifetime PRO free for life—even after paid plans launch.
This update delivers smarter Evolve Plan training and better Cardio Evolve Plan coaching:
• Machine taken? Move any exercise to later in the week. Your Evolve Plan still counts it toward its originally scheduled day.
• Swap any exercise for a smart, same-muscle alternative that matches your equipment—just for today or throughout your Evolve Plan. Your Evolve Plan preserves the progress of removed exercises in case you add them again.
• Each exercise in your Evolve Plan now adapts individually to your recent performance, with cleaner rep ladders and smarter weight progression.
• Choose your goal—Strength, Hypertrophy, Endurance, or General—and your Evolve Plan adjusts rep ranges and weight increments accordingly.
• Existing Evolve Plans receive every improvement automatically. There’s nothing to recreate.
New to cardio? The Cardio Evolve Plan now eases you in properly, beginning with walks at your chosen session length and progressing week by week into walk/run intervals and full runs.
We also fixed vocal coaching so it continues while Strontr is in the background or your phone is locked, fixed workout-day reassignment, and improved rest rule options, day merging, auto-adjusting rest timers, NEXT UP set visibility, and translations across all 11 languages—plus various other fixes.
