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 calories with AI. Stay hydrated. All in one app.

WHY FASTFLOW?

Most fasting apps only track time. FastFlow combines intermittent fasting, AI calorie tracking, water tracking, and an AI coach in one app — so you actually see results.

AI CALORIE COUNTER & FOOD TRACKER

Snap a photo of your meal and let AI estimate calories, macros, and nutrition instantly.

• AI photo calorie estimator — snap and track
• Macro breakdown (protein, carbs, fat)
• 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 protocols:

• 16:8 — 16 hours fasting, 8 hours eating
• 18:6 — Intermediate for faster results
• 20:4 — Warrior protocol for experienced fasters

Watch your body enter fasting zones in real time:

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

Get notified when you hit each zone and when your fast is complete. Timer runs even when the app is closed.

WATER TRACKER & HYDRATION REMINDER

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
• Smart hydration reminders throughout the day
• Daily and weekly water intake history

AI FASTING COACH

Ask your AI coach anything about fasting:

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

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

TRACK YOUR PROGRESS

• Fasting streak counter — build your daily habit
• Weekly and monthly fasting summaries
• Time spent in each fasting zone
• Weight tracking with trend graphs
• Water intake history and streaks

FASTING FOR WEIGHT LOSS

Intermittent fasting is one of the most effective ways to lose weight naturally:

• Burns stored body fat during fasting windows
• Boosts metabolism and fat burning
• Reduces insulin levels
• Promotes autophagy — your body's cellular cleanup

Studies show intermittent fasting helps with weight loss, improved metabolism, better focus, and longevity.
