Start when you stop eating, end when you're ready. Journal — a new tab showing one day at a time: your fasts, weight, water, electrolytes and your daily check-in, with a week strip to move between days. Ketones and glucose — log your blood levels in the units you already use. Coming from Zero? Settings → Import fasting history brings your history with you. Milestones now unlock as you earn them, with a kilogram ladder for metric units instead of converted pounds. Settings → Features lets you hide any card you don't use. ### 1.5 — 2026-09-11 • LeanFast now speaks your language: Spanish, Portuguese, German, French and Italian. • A fresh look: your running fast front and centre, your week at a glance, and light mode — or keep dark in Settings. • A proper celebration when you finish a fast, with a card you can share. • Weigh yourself on a smart scale? Connect Apple Health and your weigh-ins appear automatically. • Set a fasting schedule and get a reminder when it's time to start, with a one-tap "Start fast now". • On a free trial? We'll remind you 2 days before it ends, and you can manage or cancel right from Settings. • A smarter weight trend based on your recent weigh-ins. • LeanFast Pro is now offered as Monthly or Yearly. ### 1.4 — 2026-08-08 • LeanFast now runs on iPhones with iOS 17 or later — previously it required a much newer version, so many iPhones couldn't install it at all. • Live Activity & Dynamic Island: see your fast counting down on the Lock Screen without opening the app. • The month calendar now shows how long you fasted each day, and tapping a day shows the exact start and end times. Shorter fasts are shown too, instead of disappearing. • Weights and heights can now be entered in kg and cm. • Onboarding is shorter, has Back and Skip, and your first fast starts right away. Body stats are optional. • Fixes: a skipped starting weight no longer records a 0 lb entry that flattened your weight chart; ending a fast no longer cancels your other reminders; the paywall always shows live prices from the App Store. ### 1.3.1 — 2026-07-17 • Every install now starts with a FREE week of Pro — no payment info needed • Adjust a running fast's start and end time — hit Start late? Fix it in one tap • Fixes an issue that could prevent the AI coach from connecting • Pro now offers a Monthly plan • The yearly plan still includes a 7-day free trial ### 1.3 — 2026-07-09 This update makes LeanFast more helpful and more motivating: • New daily Fasting Score with a simple, self-explaining breakdown • Eating-window card — know exactly when you can eat next • Goal-aware "Will this break my fast?" guide • Fast completion celebration with a shareable win card • Forgiving streaks that survive a rest day • Log a fast you started earlier, or set a custom end time • Optional cycle/menopause and GLP-1 guidance • Reliability and sharing fixes ## Apps similar to Fasting Tracker | App | Rating | Price | Category | | --- | --- | --- | --- | | [Esurio \| Intermittent Fasting](https://appshunter.io/ios/app/esurio-intermittent-fasting/id6786334795) | — | Free | Health & Fitness | | [FastingForge - Fasting Timer](https://appshunter.io/ios/app/fastingforge-fasting-timer/id6798405285) | 5.0 (3) | Free | Health & Fitness | | [Fastix: Intermittent Fasting](https://appshunter.io/ios/app/fastix-intermittent-fasting/id6760931577) | — | Free | Health & Fitness | | [The Fast: Fasting Timer](https://appshunter.io/ios/app/the-fast-fasting-timer/id6813492448) | 5.0 (4) | Free | Health & Fitness | | [xHours - Intermittent Fasting](https://appshunter.io/ios/app/xhours-intermittent-fasting/id6763129519) | — | Free | Health & Fitness | | [Gymetric](https://appshunter.io/ios/app/gymetric/id6744819382) | — | Free | Health & Fitness | ## More apps by Md HASAN - [SubWatch-Subscription Tracker](https://appshunter.io/ios/app/subwatch-subscription-tracker/id6759355594) - [QuitTrack — Quit Any Bad Habit](https://appshunter.io/ios/app/quittrack-quit-any-bad-habit/id6759385999) - [FamilyBridge: Care & Connect](https://appshunter.io/ios/app/familybridge-care-and-connect/id6759393825) - [MoodBit](https://appshunter.io/ios/app/moodbit/id6759418672) - [LandlordKit: Rent & Tax](https://appshunter.io/ios/app/landlordkit-rent-and-tax/id6759428782) - [BudgetQuest](https://appshunter.io/ios/app/budgetquest/id6759439469) All apps by Md HASAN: https://appshunter.io/developer/1878266203 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
