Your training. Your recovery. On iPhone and Apple Watch.
LeibFit plans your strength training around your equipment, your goal and your week - and shows you every morning how much you can take today. With the watch you already wear, or straight from your fitness band. No account, no cloud, no tracking, everything stays on your device. The first 7 days are fully open - after that your numbers stay free.
YOUR PLAN KNOWS YOUR EQUIPMENT
Tell it once what you have: barbell, dumbbells, machines, bands or just bodyweight. LeibFit only plans with what is actually there - at home, at the gym or both. 91 exercises with form cues, alternatives and illustrations.
AI OR BUILT BY HAND
Have your week put together - or build it day by day yourself. Split, volume and starting weights are calculated deterministically; the AI only picks from the vetted exercise database, it invents nothing.
SLEEP, RECOVERY, LOAD
Three numbers, every morning:
- Recovery 0-100 from heart rate variability, resting heart rate and sleep - measured against your own 30-day baseline, not somebody's average.
- Sleep with a stage timeline and a need model: learned baseline, sleep debt, naps and a bedtime suggestion.
- Load 0-100 from heart rate zones and training volume, with a daily target that follows your recovery.
Plus your week as a strip, today's heart rate curve and last night's vitals. Works with any watch that writes to Apple Health.
YOUR BAND, WITHOUT THE MAKER'S APP
If you wear an Amazfit Helio Strap, LeibFit talks to it directly over Bluetooth: sleep stages, heart rate variability, resting heart rate, oxygen, respiration, temperature and pulse are fetched by the app itself - once after you wake up. You decide which source provides your night; they are never mixed. This link uses an unofficial interface - a firmware update by the maker can break it.
RUNNING AND CYCLING
Say which days you run or ride and whether you want base or speed. LeibFit works out today's session: duration, heart rate zone and pulse window - matched to your recovery, your load so far and a strength session on the same day.
JOURNAL: WHAT LINES UP FOR YOU
A short round of questions each morning: alcohol, stress, caffeine, screen time. After enough days LeibFit shows which answers coincide with your recovery, sleep and load - with effect size and sample size. Correlations, not causes.
ADJUST INSTEAD OF PUSHING THROUGH
Your weight suggestion learns: hit all your reps and it goes up next time - if your recovery is low, the increase is skipped. On weak days LeibFit takes unfinished sets out, reversible with one tap. Every adjustment is explained.
DURING THE SESSION
Every set ticked off directly, "last time" right beside it, and the rest timer reaches you even with the app closed. The same on Apple Watch, including the recording to Apple Health and a complication for your watch face (watchOS 10 and later). History and the weekly report then sum up volume, recovery and training.
YOUR DATA IS YOURS
No account, no servers, no analytics SDK. Health, journal, reminders and cycle context are switched on one by one - or not at all. Export any time.
FREE AND LEIBFIT PRO
The first 7 days everything is open - no subscription, no payment details, nothing to cancel. After that the three rings, history, journal and export stay free. Pro unlocks the training side: create a plan, start workouts, the adjustment to your recovery, the breakdown behind the rings and the journal correlations - 6.99 EUR/month or 44.99 EUR/year. The subscription renews automatically unless you cancel; any time via your Apple ID.
Note: coach chat, AI exercise selection and free-text equipment recognition need Apple Intelligence and iOS 26. Everything else runs on iOS 17.6 and later without AI.
