Your daily readiness every morning in one number from 0 to 10, for iPhone and Apple Watch, no band and no subscription required. LeibFit combines recovery, sleep and the strain you have already carried today into your readiness. An arc shows where you are today and where you usually are. Your strength training adapts to it. Works with any watch that writes to Apple Health, or directly with your fitness band. Everything stays on your device: no account, no cloud, no tracking. YOUR READINESS IN ONE NUMBER A number from 0 to 10 and a word: Go for it, Ready, Pace yourself, Take it easy, In reserve, Wind down. The arc shows your personal range from the last 30 days, and below it you see which signals carry today's number. Missed the night? LeibFit estimates with your answer to "How fit do you feel?". Personal bests show up right away. SLEEP, RECOVERY, STRAIN Three lenses in the Health tab, each with its own arc and your own range: - Recovery from HRV, resting heart rate and sleep, measured against your own 30-day norm. - Sleep with stages, need, sleep debt, naps and a bedtime for tonight. - Strain from heart rate zones and training, with today's target. Share any area or personal best as an image. Plus 30-day trends, heart rate curve and vitals. YOUR PLAN KNOWS YOUR EQUIPMENT Tell LeibFit once what you have: barbell, dumbbells, machines, bands or bodyweight. It only plans with what you own, at home, at the gym or both. 91 exercises with explanations. STRENGTH AND CARDIO IN ONE WEEK The weekly view shows strength and cardio days side by side, plus your weekly strain against your usual range. AI plan, your own plan or free training. For running and cycling, LeibFit works out today's session: duration, zone, heart rate window. ADAPT INSTEAD OF GRINDING Your weight suggestion learns. Hit all reps and it goes up next time. Low recovery and the increase waits. On weak days LeibFit removes unfinished sets. DURING YOUR WORKOUT Check off every set, "Last" is right next to it, today's strain and target are in view, the rest timer runs as an arc. The same on your Apple Watch, with complications for readiness and strain. GOALS, HONESTLY ESTIMATED Running, weight, fitness or strength goal. The arc shows the way from start to goal and where you typically are this week, as a range, never a promise. No smart scale? Just enter your weight. YOUR BAND, DIRECTLY Wear an Amazfit Helio Strap and LeibFit fetches your night directly via Bluetooth, without the maker's app. The connection uses an unofficial interface; a firmware update can interrupt it. JOURNAL: WHAT LINES UP FOR YOU A short morning check-in: alcohol, stress, caffeine. After enough days you see which answers line up with recovery, sleep and strain. Correlations, not causes. YOUR DATA IS YOURS No account, no servers, no analytics SDK. Health, journal and reminders are switched on one by one. Export any time. FREE AND LEIBFIT PRO Readiness, sleep, recovery and strain, journal, your goal with feasibility, sharing and export are free, no subscription. Pro unlocks: creating plans and starting workouts, free training, adapting to your recovery, history and weekly report, the way to your goal, the fitness lens, your own norm and journal correlations. Try Pro free for 7 days, then โ‚ฌ6.99/month or โ‚ฌ44.99/year. The subscription renews automatically unless cancelled, any time via your Apple ID. Note: coach chat and AI selection need Apple Intelligence and iOS 26. Everything else runs on iOS 17.6 or later without AI. Guidance, not diagnosis. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
