555 minutes
The 555-minute timer is designed for a long countdown with the ability to start, pause, and reset with a single tap. Full-screen mode is available, which helps you fully focus on the time. The end of the countdown is accompanied by a sound — you can choose a melody, adjust the volume, or turn off the signal altogether.
The timer interface has a built-in time converter that shows how many 555 minutes there are in seconds and hours. The tag is adaptive and works correctly on all devices, from smartphones to computers.
