## What is Fastyn?

Fastyn is the fastest and most elegant way to track your fasts. Forget complicated menus and manual setup: just choose how many hours you want to fast, tap “Start”, and let the app handle the rest.

Designed with a modern glassmorphism style, smooth animations, and thoughtful personalization, Fastyn turns intermittent fasting into a clear, visual, and motivating experience you can rely on every day.

What makes Fastyn different is its smart logic. The app doesn’t just start a timer, it helps you start at the right moment.

Smart Start suggestions
- Based on the current time and your habits, Fastyn suggests the best moment to begin your fast, such as “Tonight” or “Tomorrow morning”.
- You also get clear, persuasive reasons like “Ideal for relaxing before sleep”, so it’s easier to stay consistent without overthinking.

Live physiological phases
- During your fast, Fastyn shows your estimated fasting stages in real time, such as fat burning, ketosis, or autophagy, directly on the home screen and widgets.
- You always know where you are in your fasting journey at a glance.

What you can do with Fastyn
- Free duration: set any number of hours (for example, 8 h, 12 h, 20 h…) and start your fast instantly.
- Live timer: track elapsed time, estimated calories burned, and fasting progress with an intuitive visual chart.
- Estimated calories: see an estimate of how many calories you may have burned during your fast.
- Smart cards: keep your key metrics (fasting phase, BMI, streaks, goals, and more) always visible on the main screen.
- Weight log: record your measurements, explore interactive charts, and project your progress toward your goals.
- Fasting calendar: review your daily and multi-day fasting history to understand your consistency over time.
- Smart notifications: receive end-of-fast alerts, hydration reminders, and motivational tips to stay on track.
- Customizable widgets: monitor your progress from your Home Screen without opening the app.

Set your hours, tap “Start”, and experience fasting in a simple, intelligent, and visual way.
