Multi-function timer

This multi-functional timer is a tool that supports parallel timing for multiple tasks, allowing you to manage multiple countdown timers and stopwatches simultaneously without interference. Core features: ⏱️ Multiple countdown timers—Run multiple countdown timers simultaneously, each with its own name and duration. Each timer operates independently, automatically sending a notification and playing a sound when it reaches zero, and automatically recording the completion time and total time. ⏱️ Multiple stopwatches—Run multiple stopwatches simultaneously, each operating independently. Supports pause, resume, and reset; automatically records the time when manually stopped. 📊 History—Automatically records the completion time, name, and total time when a countdown reaches zero or a stopwatch is manually stopped, for easy review. Extended functionality: Supports offline use; all data is automatically saved in your local browser and is not lost when pop-ups are closed. The interface is clean and clear, supports custom timer names (click the name to modify), and is intuitive and easy to use. Developed based on Manifest V3, with streamlined permissions; only requests storage, alarm, notification, and offline audio playback permissions, and does not collect any user data.
