20 second timer
A free 20 second timer for the three jobs that need exactly this length: handwashing, eye breaks and Tabata work rounds. It loads ready at twenty seconds, so one tap on Start is all it takes, and it repeats if you want it to. Also searched as 20 sec timer, 20 seconds timer, twenty second countdown.
Three things that take 20 seconds
| Task | Why 20 seconds | Tip |
|---|---|---|
| Handwashing | The CDC's minimum scrub time with soap | Open the dedicated handwashing timer on a kitchen or bathroom tablet |
| 20-20-20 eye rule | Every 20 minutes, look 20 feet away for 20 seconds | Pair it with the 20 minute timer set to Repeat |
| Tabata work round | 8 rounds of 20 seconds on, 10 seconds off | The Tabata timer page explains the full workflow |
Repeat for intervals
Tick Repeat and the twenty seconds restart about a second after each alarm. For 40/20 training, set this timer to Repeat and work through two beeps, then rest for one. The 10 second timer does the same trick for Tabata rest.

Frequently asked questions
Why is handwashing 20 seconds?
The CDC recommends scrubbing with soap for at least 20 seconds, which is long enough to lift most germs from the whole hand. Humming "Happy Birthday" twice takes about the same time.
How do I use this for the 20-20-20 rule?
Open the 20 minute timer with Repeat for the reminder, then use this 20 second timer to look at something 20 feet away until the alarm.
Does the alarm work on a phone?
Yes, as long as the screen stays on. Most phone browsers mute audio once the screen locks.
