This timer runs 15-minute focus blocks with 5-minute breaks. It is deliberately small: the goal is not to get a lot done in each block, it is to make starting so cheap that you actually start.
Use it on days when a 25-minute block feels like too much to promise, when you are avoiding something, or when your attention is simply not there yet. Many people find it especially helpful with ADHD.
Small blocks beat good intentions
Procrastination is rarely about the work itself. It is about the cost of beginning — the moment you have to commit to something that feels big and uncertain. Fifteen minutes shrinks that commitment to something your brain is willing to agree to.
And once you are in, you will often keep going past the chime. That is the point. If you do stop after fifteen minutes, you still did fifteen minutes more than you would have.
Grow it once it stops being hard
When three or four 15-minute blocks in a row feel easy, move up to 25. The short timer is a ramp, not a permanent home — though it is a perfectly good one on a bad day.
