Fasty is the simplest way to track intermittent fasting โ€” 16:8, 18:6, 20:4, OMAD, or custom. One tap to start. Live Activities keep your progress on the Lock Screen without opening the app. Pick a plan, tap Start, and let Fasty take care of the rest. Your fasting timer lives where you actually look: the Home Screen widget, the Lock Screen Live Activity, and the Dynamic Island, so you always know how long you have left without opening the app. WHY FASTY - Quiet by design. No streak shaming, no animated pressure, no push spam. - Local-first. Your data stays on your device. No account. No backend. No tracking. - Just enough features. A timer, proven plans, history, widgets, and Live Activities. PLANS INCLUDED - 16:8: the most popular daily window. - 18:6: a tighter eating window for experienced fasters. - 20:4: the Warrior style, one main meal. - 24h: a full-day fast for an occasional reset. WIDGETS & LIVE ACTIVITY Add the Fasty widget to your Home Screen or Lock Screen and your remaining time updates automatically. When you start a fast, a Live Activity appears in the Dynamic Island and on the Lock Screen so progress is one glance away. NOTIFICATIONS Fasty sends a single local notification when your fasting window completes. No marketing pushes, no streak nags. You can turn notifications off any time in iOS Settings. PRIVACY Fasty does not collect data. There is no sign-in. Your fasting history lives only on your device and is shared with the widget through Apple App Groups, never sent to a server. MEDICAL DISCLAIMER Fasty is a habit-tracking timer, not medical software. Fasting is not appropriate for everyone. If you are pregnant, breastfeeding, under 18, have a history of eating disorders, diabetes, any chronic condition, or are taking long-term medication, consult a qualified healthcare provider before starting any fasting regimen.
