Why 15 minutes (not 25)

The classic pomodoro is 25 minutes — pulled from Francesco Cirillo's 1980s research on focused work. That research wasn't ADHD-calibrated. For ADHD adults specifically, 15 minutes is the sweet spot multiple attention studies have landed on: long enough to actually make progress, short enough that your prefrontal cortex agrees to it without negotiation. The difference between "finishable" and "intimidating."

You can absolutely use 25 or longer if it works for you — pick whatever your brain agrees to today. The point of a timer isn't to be heroic; it's to be sustainable.

The two rules that make pomodoro actually work

Pick ONE specific task before you start. "I'll focus for 15 minutes" is wishful. "I'll write the introduction paragraph" is a task. The bounded task plus bounded time is the combination that gets used.

Put your phone out of arm's reach. The timer is the easy part. The behavioral commitment is moving the phone. If you do nothing else from this paragraph, do that.

Honest limitations

This timer works in your browser. If you close the tab, the timer stops (no background notifications). Keep the tab open in a side window or use a physical timer as backup if you've got a long break ahead. The streak counter is stored locally — clearing your browser data clears the count.
