A configurable Pomodoro focus timer with custom work, short break and long break lengths, session counting and an end-of-cycle chime.. Study Timer (Pomodoro) is a free online tool from the ToolsRift Study & Education Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Set your work, short break and long break lengths, then press Start. The timer counts down, chimes, and moves automatically to the next phase, tracking how many focus sessions you have completed today.
You work in a fixed focus block, traditionally 25 minutes, then take a short break of about 5 minutes, and after four blocks you take a longer break of 15 to 30 minutes. The fixed cycle protects your attention and gives you a natural, guilt-free stopping point.
Yes. Work, short break and long break lengths are all editable, as is how many work blocks happen before a long break, so you can use 50/10 deep-work cycles or short 15-minute blocks if that suits you better.
Yes. A short tone is generated with the browser's Web Audio API when each phase finishes, so no sound file is downloaded. You can mute it if you are working somewhere quiet, and the tab title also shows the time remaining.
