The Sprint zone
A pomodoro timer with sound
Sprint is four 25-minute bursts with five-minute breathers: the classic pomodoro shape, with the timer built into the sound. A bowl marks each change, so you never watch the clock. The sound is brisker than Deep Work, for quick, list-clearing work.

Made live, made for this
Sprint is generated fresh in your browser each time you press play: nothing is streamed, recorded or repeated on a loop.
Headphones make it richer. On speakers it adapts so it still works out loud.

Questions about the Sprint zone
Can I change the lengths?
Yes. Ask the guide for “4 blocks of 30 with 10-minute breaks”, or edit the blocks in Plan.
Is this the Pomodoro Technique?
It uses the same 25 and 5 minute shape. Solfeggio is not affiliated with any trademark; it simply plays the timer as sound.
