How to use the online timer
Fifty minutes of work and ten away suits tasks that take a long time to get into: writing, drawing, code, anything where the first ten minutes are spent reloading everything you were holding in your head yesterday. Where twenty-five minutes ends just as the work is getting going, fifty leaves room for the slow part and the productive part in the same block.
The trade is that fifty minutes is harder to start and harder to protect, so the surroundings have to do more of the work: notifications off, phone elsewhere, and a clear idea of what the block is for. Keep this browser tab open for the whole stretch, because the countdown belongs to the page rather than to anything running in the background.
Ten minutes is a real break and worth treating as one — away from the desk, ideally moving. Two of these blocks fill a morning cleanly and map neatly onto an office day that starts early, which is most of them here. If concentration reliably gives out at forty minutes, that is useful information: shorten the block rather than pushing to fifty out of principle.
Common questions
When is fifty minutes better than twenty-five?
For work that takes a long time to get into — writing, analysis, design, difficult code. Twenty-five minutes can end just as the useful part begins, where fifty leaves room for both stages.
What if I run out of concentration at forty minutes?
Shorten the block. That is useful information rather than a failure, and a completed forty-minute block does more than a fifty-minute one spent watching the last ten tick away.
