How it works
- Tap Start. The ring runs down from 4:00:00.
- At this length, use the app on your phone rather than a browser tab you have to protect.
- A tone marks the end.
- If you care about a specific clock time rather than a duration, an alarm fits better.
Frequently asked questions
- What is a four hour timer for?
- Half a working day, a long low-temperature bake or smoke, a long exam block, or the shorter fasting windows people time. It is long enough that most people want the reminder rather than watching it.
- Is a browser tab reliable for four hours?
- Honestly, no. It works while the tab is open and the machine is awake, but four hours is long enough for a sleep, an update or a closed window to end it. Use the app on your phone for this, or set an alarm at the clock time you actually care about.
- Timer or alarm at this length?
- Usually an alarm. Past a couple of hours, people almost always mean a moment ("wake me at six", "it comes out at half past") rather than a duration, and an alarm survives everything a countdown does not.
