Pomodoro timer
Start it and work. It switches to a break on its own and chimes when it does.
The countdown is in the tab title too, so it is readable from whatever you are actually working in.
25:00
No focus sessions finished yet in this tab.
Nothing is stored. Close the tab and the count goes with it, because there is no account here to keep it in. The countdown is worked out from the clock rather than counted down, so leaving this tab in the background and coming back to it shows the right time rather than however far a throttled timer got. The chime is two tones generated in the page, not a sound file, so nothing is downloaded to make it.
Questions
- Is anything I type sent anywhere?
- No. Every tool here runs in the page itself. There is no server that receives your grades, your essay or your sources, and you can check it in your browser's network tab: using a tool produces no request carrying what you typed.
- Does it keep a history of my sessions?
- No. It counts the sessions finished in this tab and forgets them when you close it. Keeping a history would need somewhere to keep it, and the only thing this site stores is an email address.
- Will it keep time if I switch tabs?
- Yes. Browsers throttle timers in background tabs to around once a minute, so a timer that counted down by one each second would be minutes wrong when you came back. This one works out the time left from the clock, so it is right whatever the browser did while it was hidden.
- Where does the chime come from?
- It is generated in the page: two sine tones a fifth apart with a soft envelope. No sound file is downloaded, which means nothing to host and nothing to load. Browsers only allow audio after you have interacted with the page, so the first chime works because you pressed start.
- Why 25 and 5?
- That is the pomodoro convention, and it is only a convention. Both are editable up to two hours, so if you work in 50 minute blocks or 15 minute ones, set them and ignore the name.
