FastFlow: Fasting & Water App

FastFlow is the smart intermittent fasting tracker, AI calorie counter, and water tracker that helps you lose weight, burn fat, and stay hydrated — all with AI-powered guidance.

Track your fasts. Count your calories with AI. Stay hydrated. All in one app.

WHY FASTFLOW?

Most health apps make you choose — fasting OR calorie counting OR water tracking. FastFlow combines intermittent fasting, AI calorie tracking, water intake tracking, and an AI coach in one simple app — so you actually stick with it and see results.

AI CALORIE COUNTER & FOOD TRACKER

Snap a photo of your meal and let AI estimate calories, macros, and nutrition instantly. No more manual searching through food databases.

• AI photo calorie estimator — just snap and track • Automatic macro breakdown (protein, carbs, fat) • Food scanner with AI-powered nutrition recognition • Daily calorie tracker with intake history • Set calorie goals and track your deficit • Works with any meal — home cooked or restaurant

SMART FASTING TIMER

Start your fast with one tap. Choose from popular fasting protocols:

• 16:8 — The classic. 16 hours fasting, 8 hours eating • 18:6 — Intermediate level for faster results • 20:4 — The warrior protocol for experienced fasters • Custom — Set your own fasting and eating windows

Watch your body enter different fasting zones in real time:

• Fed State (0-4 hours) — Digestion and energy storage • Fat Burning (4-12 hours) — Your body switches to burning fat • Ketosis (12-18 hours) — Deep fat burning and mental clarity • Autophagy (18+ hours) — Cellular repair and regeneration

Your fasting timer keeps running even when the app is closed. Get notified when you hit each zone and when your fast is complete.

WATER TRACKER & HYDRATION REMINDER

Staying hydrated is just as important as fasting. FastFlow tracks your daily water intake and sends smart reminders so you never forget to drink water.

• Set your daily water goal • Quick-add buttons for common amounts • Track glasses, bottles, or custom amounts • Smart hydration reminders throughout the day • See your daily and weekly water intake history

MEET YOUR AI FASTING COACH

Confused about fasting? Ask your AI coach anything:

• "Can I drink coffee during my fast?" • "What should I eat to break my fast?" • "Which fasting protocol is best for weight loss?" • "How do I handle hunger during a fast?"

Get instant, personalized answers based on your fasting history and goals.
