Twenty minutes sits between a short break and a full focus session. It is a useful time-box for a task you want to finish rather than just start.
Typical uses
- A work sprint. Not everyone can sustain 25 minutes. Twenty is a gentler first step, especially for tasks you dread.
- Lesson segments. A group task, a reading activity or a practice set. Show the timer full screen with the disk view so pupils can see how long is left. For classrooms there is also a classroom timer.
- Exercise blocks. A walk, a circuit or a short session on a bike. For repeating work and rest periods, use the interval timer.
- Housework. A "20 minute tidy" is a way to make a boring job finite. Stop when the alarm sounds, even if it is not perfect.
- Practice. Instrument practice or language study in one focused piece, followed by a break.
- Waiting and resting. Letting a face mask, glue or dough sit, as the instructions say.
Advice for a 20 minute block
Write down the one thing you are doing before pressing Start. Put your phone out of sight. When the alarm rings, decide deliberately: take a break, or start another block. Using the stopwatch for a few tasks will tell you how long things really take, which makes your future time-boxes more realistic.
Controls
Press Start or the space bar, Pause to hold, and Reset to return to 20:00. Full screen fills the display. Test sound plays the alarm so you can set the volume.

The 20-20-20 rule and a repeating 20 minute timer
The American Optometric Association describes the 20-20-20 rule for digital eye strain: every 20 minutes of screen use, look at something about 20 feet away for 20 seconds. This page can be your 20-minute reminder.
Tick Loop under More options (or open this auto-loop link) and the countdown restarts by itself after every alarm. When it rings, look away for 20 seconds, then carry on. It is a reminder, not a medical treatment: if your eyes are sore, speak to an eye care professional.
