660 seconds
A 660-second (11-minute) timer is a handy tool for various tasks. Use it for short presentations, exercises, or meditation sessions. The built-in audio signal will notify you about the end of the countdown — select one of the available ringtones and adjust the comfortable volume in the menu.
Full-screen mode simplifies the interface as much as possible, leaving the focus on the timer and the main control buttons. This is especially useful for group classes or when you need to keep track of time from afar.
For easy scheduling, an automatic converter is located next to the timer, which calculates how many 660 seconds will be in minutes.
