About

Leptin is a metabolic-health lifestyle app that brings fasting, eating, movement, and coaching into one daily rhythm. It is organized around five pillars: Fast, Eat, Move, Coach, and Insights. FAST - a timer built around metabolic phases rather than a plain countdown, with a Live Activity so your progress stays on the lock screen. EAT - break-fast and meal guidance, meal logging with photos, and a nutrition database, so progress isn't undone in the first bite. MOVE - guided workouts with an audible coach that calls out each phase and keeps going while your phone is locked, interval walking sessions, freestyle logging, and movement suggestions tuned to how long you have been fasting. COACH - an AI coach that adapts to your fasting state, goals, and history. INSIGHTS - streaks, history, and progress over time, plus Apple Health sync so your workouts and activity stay in step with the rest of your health data. Leptin works offline: sessions and logs are captured on the device and sync when you are back online. Leptin is a wellness and lifestyle app. It is not a medical device and does not diagnose, treat, cure, or prevent any disease, and it does not provide medical advice. The in-app AI coach is an assistant, not a clinician, and its guidance should never be relied on for medical decisions. Consult a qualified healthcare professional before starting any fasting, nutrition, or exercise program, especially if you are pregnant or breastfeeding, under 18, or living with a medical condition such as diabetes, heart disease, low blood pressure, or a history of disordered eating. Stop and seek medical attention if you feel faint, disoriented, unusually short of breath, experience chest pain, or feel unwell in any way. Core fasting tracking, timers, and insights are free. SUBSCRIPTIONS Leptin offers optional auto-renewable subscriptions (subscription group "Leptin Plans") that unlock the AI coach with a monthly credit allowance plus expanded access to guided programs: - Basic: $9.99/month or $99.99/year - Premium: $19.99/month or $199.99/year - Unlimited: $49.99/month or $499.99/year Payment is charged to your Apple ID at confirmation of purchase. Your subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. You can manage or turn off auto-renew in your App Store account settings after purchase.

What's New in Leptin

1.2.10

September 7, 2026

NEW ICON Leptin has a new mark. You will see it on your home screen after updating. YOUR MEALS SHOW UP WHERE YOU EXPECT THEM Meals now appear in the calendar day view, on today and on any past day. A meal you log on one device now shows up on your others, and one you delete disappears from them, without waiting for the next day. LOGGING IS EASIER TO GET RIGHT Logging a meal through the coach arrives already filled in, photo and all. Correcting something you logged now works from every screen that shows it, including intakes, which previously could not be edited at all. A BETTER COACH Your conversation history goes back as far as it actually reaches, instead of showing only the most recent one. The coach opens without the keyboard covering its menu, the message box says what it can do, and it no longer asks the same question twice. SIGNING IN The Google and Microsoft buttons sit side by side again instead of stacking. SUBSCRIPTIONS The free plan is no longer offered as something to buy, and if a purchase does not go through, the app now tells you why.
