About this app

Fasting Timer is a simple, no-fuss intermittent fasting tracker designed to help you build healthy fasting habits. It's the ultimate app for ADF fasters. Each day when you start your fast, it's just one click, even when you forget to start it at your normal fasting time.

WHY THIS APP?

Most fasting apps are bloated with features you don't need - meal plans, calorie counters, articles, notifications, premium upsells. You just want to track when you started and when you'll finish.

Fasting Timer does exactly that. Nothing more, nothing less.

FEATURES

• One-tap start - Your preferred duration is ready. Just tap and go.
• Remembers your preferences - Opens exactly how you left it
• Clean dark interface - Easy on your eyes at any hour
• Flexible durations - 16:8, 18:6, 20:4, OMAD, extended fasts up to 5 days
• Schedule ahead - Start now or set a future/past start time
• Visual progress - Beautiful gradient ring shows your progress
• Overtime tracking - Keep going past your goal? We'll show you how far
• History - Review your completed fasts anytime
• Share achievements - Export your results as images
• Works offline - No account required, no internet needed
• Tablet optimized - Looks great on tablets too

NO FRICTION

No sign-up. No tutorials. No premium tier. No ads. No notifications begging for attention.

Just open and fast.

Free forever. From TrainerDay.
