3 hour timer
A three hour timer with a sound at the end. Three hours is a long study block, a slow roast, a leg of a drive, or the length of a decent hike.

How it works
- Tap Start and let it run down from 3:00:00.
- Use it for things with a long, roughly fixed duration: cooking, studying, travelling.
- A tone marks the end.
- On your phone the timer survives a locked screen; in the browser this tab has to stay open.
Frequently asked questions
- What runs for three hours?
- Slow cooking is the classic one, along with a long study or work block and a stretch of driving. Three hours is also roughly where a single sitting stops being productive without a real break.
- Can I trust a browser timer for this long?
- It works, but the tab has to stay open and your machine has to stay awake, which over three hours is a real risk. For anything you would be annoyed to miss, use the app on your phone or set an alarm for the clock time instead.
- How do I break three hours into blocks?
- Most people do better in chunks than in one stretch. Six pomodoro blocks of twenty-five minutes with breaks fills roughly three hours, and the interval timer will run the pattern for you instead of you restarting a countdown.
