Pomodoro and a stopwatch that remember your activity.
One app for organised studying: a timer with focus and break intervals, activity sorted by subject, stats, tasks, habits and exam countdowns.

From focus to organised studying
Start the timer and get studying. The app remembers everything else.
Focus in blocks
Pomodoro alternates focus and breaks, and you set the length. The stopwatch runs until you stop it. While you focus, the rest of the screen steps back.
Every session is saved to its subject
You can also add a note about what you covered. Forgot to start the timer while studying? Add the session afterwards with the “add manually” button.
Your day and week under control
Today's trace shows your study blocks on a timeline, the weekly overview compares days with the daily goal you set, and the calendar colours each day by the work you did.
What is Časostopa good for?
For studying
Study for exams with a pomodoro timer or a stopwatch. Your study sessions are saved by subject as you go, so over time you see how much time you really give to studying. You can also keep an eye on the time left until exams and other important events, keep track of tasks or jot down a quick note without stopping the timer.


For projects and client work
Časostopa also works for developers and freelancers. The only difference is that instead of school subjects you keep records for individual projects or clients.

For consistency
Besides the time you track, Časostopa keeps an eye on your regular habits and the list of things you need to do.

What does your studying really look like?
Every month Časostopa shows you an overview of your activity. It adds up time per subject and shows active days, your best day and a comparison with last month. You see right away where you're ahead and where to add more.
Sample data.
Everything around studying in one place, not just a timer
How many days until the exam, what needs doing and what you want to do regularly. All in one app that helps you organise your studies.
Countdown
How long until an exam, a test or a deadline.
Tasks
Three priorities side by side. Finished tasks are under the “done” button.
Habits
Check them off day by day and see your streak and the last 30 days.
For focus
4 Working memory
Working memory holds information for a few seconds while we work with it, for example when doing mental arithmetic or following a long sentence.
Baddeley and Hitch (1974) described it as a system of three components: the central executive, the phonological loop and the visuospatial sketchpad.
The phonological loop stores the sound of words and refreshes it through inner rehearsal. The visuospatial sketchpad handles images and the position of objects.
In 2000 Baddeley added the episodic buffer, which links the contents of working memory with long-term memory.
Questions
Isn't it enough to just study?
Blocks with breaks hold your attention longer than endless hours over your notes. Your records show how much you really get done, and the daily goal and streak help you stay consistent.
Does it work for work too?
Yes, instead of subjects you create projects or clients.
Do I need an account?
No. Without an account your data stays in this browser. With an account (email or Google) it syncs across your devices.
How much does it cost?
Nothing. Časostopa is free.
Does it work on my phone?
Yes, you can use the app in the browser on your phone and on your computer.
Can I add a session I forgot to time?
Yes, with the “add manually” button next to recent sessions.
Can I download or delete my data?
Yes. Export to a file is in Settings, and you can delete your account with all its data.
