Blinker
A Flipper Zero application that blinks LEDs with a decreasing frequency over time. Unlike traditional Pomodoro timers, it provides visual feedback through LED blinks that gradually slow down.
This application can be downloaded from Flipper Lab.
This project was inspired by a discussion in this Hacker News thread.
