iF vs Leptin

iF - InterFast makes intermittent fasting simple and helps you adopt a healthy lifestyle.  Intermittent fasting brings several health benefits and has helped thousands of people lose weight and be healthier. With iF - InterFast, you can easily add your meals, drinks and activities to monitor your daily calorie count. Performance is saved and can be viewed in the stats. Monitor and record your weight at regular intervals and track your progress. iF -InterFast also calculates your TDEE which serves as a guide in monitoring your calorie intake and can read your active calorie burnt from Health App.

Leptin brings when you eat, what you eat and how you move into one plan for the day, and adjusts it when life gets in the way. It is not a calorie counter. There are no targets to miss and no warnings attached to a meal, because the point is the pattern over weeks, not a number at dinner. And it is not only for people managing a diagnosis. This is simply how eating and movement work, for everyone. Together these shape your metabolic health, which is the thing underneath weight, energy and how you feel through the day. 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.
