Keep your fasting window on your Lock Screen, where you already look a hundred times a day. Set your eating hours once. The rest follows on its own, every day. A clean widget shows what is happening right now: "Fast until 8:00 AM" while you fast, "Eat until 6:00 PM" once your window opens. No numbers ticking, no app to open, just a glance. WHAT YOU GET - Your fast, right on the Lock Screen, in real time - A widget for the Lock Screen and the Home Screen - Fasting and eating that switch automatically at the right time - Gentle reminders when a fasting or eating window begins - Set it once and let it repeat every day HOW IT WORKS Pick when your fasting starts and how long it lasts. Your eating window fills in the rest. Add the widget to your Lock Screen and you are done. It quietly follows your schedule from then on. MADE SIMPLE ON PURPOSE No food logging, no charts to keep up with, no clutter. One glance tells you where you are in your day. PRO Unlock everything with a subscription. It is auto-renewable and billed monthly, and it renews until you cancel. You can cancel anytime in your Apple Account settings. Payment is charged to your Apple Account at confirmation.
