TeacherTimer is a session timer app specifically designed for the classroom. Simply set a time, either by typing directly into the timer or using the adjustment buttons and hit Go!

Click the pop-out window button to display and hide the timer on a second screen or projector while still leaving your main screen for other work. Or, if you prefer to mirror your screen, you can set the pop-out window to float above other windows.


- Easily display the timer on a second screen or projector
- Quick set the time by directly typing into the timer
- Optionally float the timer window above other windows
- Make live adjustments while the timer is running for true 'teacher time'
- Add an optional title to your timer
- Make the timer background transparent to easily overlay above other information.

Use it with my primary class when they are completing a timed activity and I still need to use my display for work.

Simple, done well

Simple timer app that stays front and centre. Easy to use and I’m sure I’ll use it repeatedly
