16/8 Fasting & Water Tracker makes intermittent fasting simple—and pairs it with hydration so you feel better while you do it. Some features require a subscription. Fasting works best when you’re hydrated. A 16:8 fasting schedule supports your routine, and consistent water intake can help curb cravings and support focus. Together, they make fasting easier to sustain and more effective over time. What you can do with 16/8: Start a 16:8 fast in one tap: No complex setup, just start. See your status instantly: Know exactly when you can eat and when you’re fasting. Track water intake: Log your hydration alongside your fasting window. Stay consistent: Build a simple daily routine you’ll actually follow. Why the combo matters: The 16:8 fast helps create structure, and hydration helps you feel better during your fasting window—less distracted, more steady, and more likely to stick with it. Whether you’re new to fasting or already doing 16:8, this app helps you stay on track without overthinking it. -- Subscription Details: Some features require a subscription after the free trial, including unlimited fasting tracking and water reminders. Free users can explore the app, but continued access to premium features requires a monthly or yearly subscription. ---- Important links Privacy Policy: https://pughealth.app/privacy.html Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
