Fruit Timer is a visual countdown timer that shows the passage of time with colorful fruit cross-sections. As the timer runs, a watermelon, orange, or kiwi gradually appears clockwise, making the remaining time easy to understand through both numbers and visuals. Switch fruit at any time, pause and resume the timer, and choose sound and vibration separately while the app is open. A clear flashing animation also shows when time is up, even when both are turned off. Fruit Timer is useful for study sessions, daily routines, getting ready, cleaning up, exercise, breaks, and focused work. Features: - Set a timer from 1 second to 59 minutes 59 seconds - Watermelon, orange, and kiwi visuals - Large, easy-to-read remaining time - Pause and resume - Switch fruit while the timer is running - Separate sound and vibration controls while the app is open - Visual completion animation - Portrait and landscape support - Option to keep the screen awake during a timer - Local notification when a background timer finishes - No account required - Core timer features work offline - Optional repeatable developer support purchase with no extra benefits
