Intermittent fasting tracker & track your weight loss, water, sleep & health.
Fasting only works if it fits your life, not someone else's routine. FastSync - Fasting Tracker gives you everything you need to build a fasting habit around your body, your goal, and your schedule. This fasting tracker app is a true intermittent fasting app, built for anyone who wants to lose weight, stay in shape, maintain their weight, or simply feel more energetic. Whether you're just starting out or you've fasted for years, it works as a simple fast tracker for beginners or a detailed fasting hours tracker for experienced fasters who want every fast logged in full. **Home Screen & Lock Screen Widgets** Keep your fasting progress visible without opening the app. Add a FastSync widget to your home screen or lock screen to quickly check your fasting timer, current status, and progress throughout the day. **FEATURES:** **Fasting Timer** — A built-in fasting timer and countdown clock so you always know exactly where you stand. Keep a complete history of every session, and use the fasting timer widget to check your progress right from your home screen. **Fasting Plans** — Set your fasting schedule and follow a plan built around your goal. Browse weekly and monthly views to see your patterns at a glance, plus a consistency tracker so you know how steady you've been. Prefer guidance? Get an AI fasting recommendation built from your weight, height, age, and goals — working like a built-in fasting calculator. Pick a plan yourself, or let the AI choose one for you, and switch anytime as your goal or schedule changes. **Weight Tracker** — A dedicated weight tracker that doubles as a genuine weight loss journey tracker, not just a number on a screen. Log your weight daily and keep every entry organized as you work toward your goal. **Water Tracker** — Stay on top of hydration with a simple, built-in water tracker. Get an AI water recommendation based on your profile, or log your own daily intake. **Sleep Tracker** — A dedicated sleep tracker paired with a sleep quality tracker to see how rest connects to your fasting results, plus a recovery view for a clearer picture of your recovery. **Nutrition & Health** — A built-in nutrition tracker with an AI nutrition goal for protein, carbs, and fats, so you know how to refuel after a fast. Fasting, water, weight, sleep, and nutrition all come together in one combined health view, with reminders and notifications so you never miss the start or end of a fast, plus progress stats and charts so you can see how far you've come. **HOW TO USE FastSync - Fasting Tracker:** Enter your weight, height, age, and goal. Pick your own fasting plan and schedule, or use the AI recommendation. Start your fasting timer and check it anytime from the widget. Log your water intake, sleep, weight, and nutrition as your day goes on. Check your weekly and monthly views to track your consistency. Switch your plan anytime as your goal changes. **YOUR PRIVACY MATTERS** Your fasting, weight, water, sleep, and nutrition data stays within the app and is used only to power your recommendations and track your progress — nothing more. FastSync provides tracking tools for informational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment. Consult a qualified healthcare professional before starting any fasting program, especially if you are pregnant, have a medical condition, or take prescription medications. Not every fasting plan suits every person. FastSync flags situations and health profiles where a plan may not be a good fit, so you can make an informed decision before you start. Download FastSync - Fasting Tracker and start with a fasting tracker for weight loss, better health, and daily energy that's actually built for you.
