Fasting Clock

Features
Read full description

Your personal fasting clock, starting from your last meal. The fasting clock records the time of your last meal and shows you exactly how much time remains until your fasting goal. Key Features - Fasting Timer Record your meal time with a single tap and track the time remaining to your goal — down to the hour, minute, and second in real time. - Storybook-Style Clock A beautifully crafted clock in a fairytale aesthetic. Your fasting progress fills in as an arc sweeping clockwise from the 12 o'clock position. - Multiple Goal Settings Set several fasting goals at once (e.g., 12h, 16h, 18h) using 8 color-coded slots, and switch between them with a tap to check your progress. - Goal Reached Notifications Get notified the moment you reach your fasting goal. Starting 10 minutes before, the clock begins to glow softly in that goal's color. - Fasting History Log Review your completed fasts on a calendar view, with color-coded dots marking each achievement. Tap any day for a detailed breakdown, and use filters to explore your patterns. - Seasonal Themes Gradient backgrounds shift automatically with the seasons — spring, summer, autumn, and winter — or switch manually to whichever season you prefer. - Korean / English Support The app detects your device language automatically, with the option to change it manually in settings. Recommended For - Anyone looking to build a consistent intermittent fasting (IF) habit - Those managing multiple fasting routines like 16:8 or 18:6 - Anyone who wants to visually track and reflect on their eating patterns
