Use any screen as a big clock
- Desk or wall clock — A spare tablet or a second monitor becomes a large clock you can read from across the room.
- Exams and classrooms — Project the time so students can pace themselves without looking at their phones.
- Meetings and presentations — Keep track of the time while you speak.
- Livestreams and study-with-me videos — Show a clean clock on screen.
- Kitchens, gyms and shops — A big display is much easier to read than a phone.

Which time zone does it show?
The time zone your device is set to. If the time looks wrong, check the date and time settings on your device.
How do I keep the screen from turning off?
