Run classic 25/5 Pomodoro sprints or set your own interval. Your sessions, streaks and focus score are saved the moment you create a free account — the timer itself works without one.
The Pomodoro technique splits work into 25-minute focus intervals separated by 5-minute breaks, with a longer break after four intervals. Francesco Cirillo developed it in the late 1980s and named it after a tomato-shaped kitchen timer. FocusArx runs those intervals in your browser and records every completed sprint.
Twenty-five minutes is short enough that starting does not feel like a commitment and long enough to get past the friction of settling in. The interval also gives procrastination a deadline: you are not agreeing to finish the essay, only to spend 25 minutes on it.
The break matters as much as the sprint. Attention residue — the part of your mind still on the previous task — decays during the pause, which is why the next interval usually starts faster than the last one.
A fixed 25-minute cap interrupts flow. If you are writing, coding or solving proofs and you hit a state where the work is pulling you forward, a forced break costs more than it returns. Use a longer 50/10 or 90-minute block instead, and treat the timer as a floor rather than a ceiling.
Pomodoro is also weak for creative exploration and research reading, where the useful unit is not time but a question answered. Match the method to the task: sprints for execution, open blocks for thinking.
A plain timer ends. FocusArx scores the session, stores it against the task you set, and folds it into a streak and a focus score you can see week over week. Optional study rooms put other learners working beside you during the same interval, which is the body-doubling effect. An AI coach then turns the accumulated history into concrete suggestions about when and how long you should work.
The core timer, tasks, streaks and analytics are free. Premium is unlocked with Focus Tokens you earn by completing sessions — there is no payment step.
