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 €6.99/month or €44.99/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/ ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | LeibFit Pro – Monat | $5.99 | per month | | LeibFit Pro – Jahr | $39.99 | per year | ## Is LeibFit safe?

The dot is today, the band behind it is your personal range from the last 30 days. You see at a glance whether your readiness is high or low today, measured against you. NEW: READINESS FROM 0 TO 10 One number, one word, one sentence. Below it, the signals that carry your readiness: sleep, HRV, resting heart rate, breathing. And three rows for sleep, recovery and strain, each with its own small arc. NEW: NO NIGHT, NO GAP Didn't wear your watch overnight? Answer "How fit do you feel?" and LeibFit still estimates your readiness. In the evening LeibFit shows you when your watch or band battery is low and, if you like, reminds you to charge. NEW: PERSONAL BESTS AND SHARING Best night, best recovery or best value in three weeks: LeibFit tells you. Share any area as an image, including your runs, now with a gauge. NEW: STRENGTH AND CARDIO IN ONE WEEK The training tab starts with your week as a grid, strength and cardio side by side, plus your weekly strain against your usual range. NEW: GOALS AS A PATH The arc runs from start to goal and shows where you typically are this week. No smart scale? Enter your weight in your profile or right at your goal. NEW: LIGHT OR DARK LeibFit starts in dark mode. Choose light, dark or system in your profile. APPLE WATCH Readiness as a large arc on your wrist, your values below, and a new strain complication with today's target. IMPROVED LeibFit follows your iPhone's language, and your Apple Watch and widgets now speak the same language as the app. The widget always shows today and opens Today. Tapping a tab takes you back to the top. Exercise images return, reworked, in the next update. As always, everything stays on your device: no account, no cloud, no tracking. ### 1.11 — 2026-09-28 NEW: GOALS, HONESTLY ASSESSED A running, weight, fitness or strength goal, set up right on Today. From your runs and your scale LeibFit tells you what is typically reachable in what time, as a range, never a promise. The strength goal measures no body value but your consistency: this many sessions a week, this many weeks. A session counts when you finish it without skipping an exercise. With Pro you see the weeks as a strip plus a checklist. NEW: FREE SESSION Something other than the plan today? Start a session from your plan, split into gym and home, with its sets and weights. Or put exercises together yourself; your last free session repeats with one tap. Your weekly plan stays as it is. NEW: YOUR STRAIN DURING THE SESSION Above the exercise list you see where your strain stands today and where your target lies, refreshed every minute from Apple Health. CHANGED: FREE AND PRO Form, numbers, journal and your goal are free from day one, no subscription and no deadline. Try Pro free for 7 days through the App Store. If you already had LeibFit, your running free week stays. The workouts list is readable without Pro; only starting is locked. History and the weekly report are now part of Pro. IMPROVED: A DAILY TARGET THAT FITS YOU Once two weeks of data are in, your strain target follows not only your recovery but also what you have been used to over the last four weeks. If you regularly train a lot, the target rises; if you do less, it comes down a little. And reaching your target leaves form to spare: it only hits 0 well above it. Everything stays on your device, as before: no account, no cloud, no tracking. ### 1.10 — 2026-09-21 This update makes LeibFit more stable and faster. IMPROVED: PERFORMANCE The app launches faster and feels noticeably more responsive, especially in the workout list and Health tab. FIXED: MINOR BUGS We fixed a number of issues that occasionally caused display glitches or freezes. Everything stays on your device: no account, no cloud, no tracking. ### 1.8 — 2026-09-13 NEW: TODAY FOLLOWS THE TIME OF DAY Morning, day, evening - your tiles on Today now sort by what fits right now. On a day off, LeibFit offers a short rest-day session that matches. NEW: PAGE WEEK BY WEEK THROUGH YOUR WORKOUTS In your workout list you now page week by week instead of unfolding long lists. IMPROVED: EDIT MOVEMENT RESTRICTIONS ANY TIME What you set during onboarding you can now change any time in your profile. IMPROVED: LIVE HEART RATE AND BAND FETCH Live heart rate from your Amazfit band now runs app-wide over a single connection, for training and recovery alike. The band fetch is split into a lean daytime run (just the heart rate curve) and the full nightly fetch. Step count follows the data source you picked, and the rings' loading animation is calmer. Everything stays on your device, as before: no account, no cloud, no tracking. ### 1.7 — 2026-09-02 NEW: AFTER THE FREE WEEK, IT KEEPS GOING Until now the app stopped after seven days unless you subscribed - a wall in front of something you had only just met. That wall is gone. Your three rings, your history, your journal and the 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. NEW: YOUR BAND WITHOUT THE MAKER'S APP If you wear an Amazfit Helio Strap, LeibFit now fetches your night itself - straight over Bluetooth: sleep stages, heart rate variability, resting heart rate, oxygen, respiration, temperature and today's heart rate curve. You can set the band up right during onboarding, and on "Today" you pick which source provides your night. They are never mixed: watch and band measure differently, and switching mid-series would look like a crash in your numbers. Note: this link uses an unofficial interface - a firmware update by the maker can break it. NEW: RUNNING AND CYCLING ARE PART OF THE PLAN Say which days you run or ride and whether you want to build base or get faster. LeibFit works out today's session from that: duration, heart rate zone and pulse window - matched to your recovery, your load so far today and a strength session on the same day. Once you have been out, LeibFit recognises the session and shows your result instead of the suggestion. NEW: THE HEALTH TAB SHOWS YOUR NIGHT Instead of three bars you now get your sleep curve with every stage, hour by hour. Plus a week strip under the rings - every bar opens its day -, today's heart rate curve, vitals with a 14-day sparkline and a 30-day detail sheet, and your sleep need as a calculation instead of a list. You can page back through past days. NEW: HEALTH ONLY, FOR NOW During setup you can now say that you only want sleep, recovery and load for the time being. LeibFit then skips the training questions and does not show you an empty plan. You can add the training side later. IMPROVED: THE SMALL THINGS YOU TOUCH OFTEN In Workouts you now page week by week instead of unfolding lists. You can reorder the exercises of a session, delete single sessions, and edit your movement restrictions later in your profile. If tonight's data has not arrived yet, the app shows your last night instead of empty rings. Everything still on your device: no account, no cloud, no tracking. ## Apps similar to LeibFit | App | Rating | Price | Category | | --- | --- | --- | --- | | [Heart Rate Zones: WristPing](https://appshunter.io/ios/app/heart-rate-zones-wristping/id6766162512) | — | Free | Health & Fitness | | [FitMesh Sync: health dashboard](https://appshunter.io/ios/app/fitmesh-sync-health-dashboard/id6779751708) | — | Free | Health & Fitness | | [BARO: Sleep & Recovery](https://appshunter.io/ios/app/baro-sleep-and-recovery/id6782239514) | 5.0 (3) | Free | Health & Fitness | | [Recovery Tracker: Readiness](https://appshunter.io/ios/app/recovery-tracker-readiness/id6767789839) | — | Free | Health & Fitness | | [Lepo: Readiness & Recovery](https://appshunter.io/ios/app/lepo-readiness-and-recovery/id6777772118) | — | Free | Health & Fitness | | [Varzo](https://appshunter.io/ios/app/varzo/id6757185090) | 5.0 (5) | Free | Health & Fitness | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
