490 hours
A 490-hour timer counts down the set interval and shows the remaining time in seconds. The user-friendly control panel lets you start, stop, or reset the countdown with a single click. In the settings, you can select a ringtone, adjust the volume, or turn off the sound completely. The built-in automatic translation of 490 hours in days, minutes and seconds is also available.
The interface is responsive and equally convenient on your phone, tablet, and computer. If necessary, you can expand the timer to full screen.
