478 minutes
The 478-minute timer makes time management simple, the counter shows the remaining minutes and seconds, and the Start, Pause and Reset buttons respond without delay. After the period ends, the selected ringtone sounds, and you can adjust or disable the sound. The built-in conversion instantly shows how many 478 minutes are in other time units, hours and seconds.
The interface automatically scales to fit the device screen and supports full-screen rotation. When you switch pages, the timer remains accurate, and the countdown is updated in the tab title so that you can always see how much time is left.
