When to use a 51-minute timer

51-minute blocks suit deep work — coding, writing, design, research. Long enough to load a hard problem into working memory.

How to run it

1. Pick ONE task. Write it down.
2. Open Promodify, set the focus length to 51 minutes.
3. Phone in another room. Start the timer.
4. When the bell rings, stop. Take a proportional break.
