Fastful: Fasting Tracker

A fast is a private commitment. Fastful keeps the time and stays out of your way: no account, no subscription, no noise. On iPhone, Apple Watch, and your Home Screen.

Fasting is an art of not doing. Your fasting app should understand this.

Fastful turns your fast into a single ring: time elapsed, time remaining, and how far past your goal you've gone. Underneath it, when you started and when you're due to finish. Start in two taps, glance whenever you like, and get on with your day.

KEEP PROMISES TO YOURSELF A fast is a private commitment. Fastful doesn't coach you, rank you, or interrupt you. It keeps the time and keeps the record, so the honest work of showing up becomes something you can see.

IT KEEPS COUNTING PAST YOUR GOAL Reach 16 hours and feel like going further? The ring wraps past 100% and keeps counting, on your phone, your wrist, and your Home Screen. Your extra hours are never rounded down to "done."

ON YOUR WRIST Start a fast from bed. Check it mid-meeting. End it at breakfast without touching your phone. The Apple Watch app holds its own: if your phone isn't nearby, what you did is queued and syncs the moment it's back.

HOWEVER YOU FAST 16:8, 18:6, 20:4, and OMAD, or extended fasts from 24 to 72 hours, or any custom window. For health, for focus, for longevity, or for faith: Fastful keeps the time the same way: faithfully, and without an opinion about it.

A HISTORY YOU CAN CORRECT Every fast as a calendar or a list, grouped by month. Forgot to stop the timer? Edit it. Fasted before you had the app? Log it. Your record should be accurate, not merely tidy.

PROGRESS WITHOUT PRESSURE Current and best streak, completion rate, hours fasted, and 7- and 30-day trends. Twenty-four milestone badges that mark real effort. Miss a day and nothing scolds you. Show up again and it notices.

YOUR DATA, ON YOUR DEVICE No account. No ads. Your fasting history is stored on your device and exports to CSV in one tap. Fastful reports limited anonymous product analytics — which features get used, never who used them, never when you ate. There's no advertising identifier and no cross-app tracking, which is why you'll never see "Ask App Not to Track."

PAY ONCE No subscription. No trial that quietly becomes one. Buy it, keep it.

MADE WITH CARE Built natively for iPhone and Apple Watch. Home Screen and Lock Screen widgets. Light, dark, or automatic. Daily reminders on the days and times you choose, and one notification when you reach your goal — the complete list of times Fastful will ever speak first.

MADE SLOWLY, ON PURPOSE Fastful is made by one person who fasts and wanted a quieter tool. No investors to satisfy, no growth targets that turn into notifications. Write to Talk to the Developer in Settings and it reaches the person who builds it.

Eat. Don't eat. Either way, Fastful will be exactly where you left it.

Fastful is a timer, not a doctor. It measures time; it doesn't know your body. Fasting isn't right for everyone — talk to a qualified medical professional before fasting, especially if you are pregnant or breastfeeding, under 18, managing diabetes or another medical condition, taking medication, or have a history of disordered eating. Longer is not automatically better. Fastful records your choices; it doesn't prescribe them.
