Coding Timer
Good code requires deep focus. Context switching is the enemy. Set your session, pick your problem, and don't surface until it's solved.
About this timer
Why developers need deep focus sessions
Research on developer productivity consistently shows that it takes 15–20 minutes to reach a state of full concentration on a coding problem. A single Slack notification can destroy this state entirely, requiring another 15–20 minutes to rebuild it. In an 8-hour workday with frequent interruptions, a developer may achieve only 1–2 hours of genuine focused coding. Timed sessions with notifications off create a protected window where complex problems can actually be solved. The mission field forces you to define the problem before you start — which is itself a significant part of solving it.
Common questions
How long should a coding session be?
60–90 minutes for complex problems requiring deep thinking. 25–45 minutes for well-defined tasks, bug fixes, or code review. Match the duration to the complexity of the problem.
Should I use a timer when pair programming?
Yes — timed sessions work well for pair programming too. Knowing the session has a defined end reduces fatigue and keeps both participants focused.
What should I do when I'm stuck mid-session?
Resist the urge to switch context. Stay with the problem. Write out what you know, what you've tried, and what the next logical step is. Most breakthroughs come after 10–15 minutes of sustained effort on the sticking point.
