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.

What’s New

Version 1.3

Bug fixes, new sound effects, laying some groundwork for more improvements soon.

-- Apologies to anyone on Big Sur who found the up/down buttons had disappeared, these should be working again.
-- Multiple sound effects to choose from now in the app preferences panel.
-- Titles should display properly if they weren't before...
-- Fixed a bug that stopped the pop out timer from centering vertically.

I've got some more improvements coming in the next update... mainly adding the option to use custom sound effects for timer completion, adjustable font and background color and automatic timer looping. If you have any problems, you can get in touch with me at

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
