# CountLink

> CountLink — app-countlink-countdown. Use this tool when you need to synchronize countdowns across multiple screens or viewers, such as for event planning, presentations, or group activities. CountLink solves the problem of disparate timers by providing a shared, account-free countdown that stays in sync for any number of viewers. It takes a countdown duration as input and outputs a synchronized timer visible to all participants.
