Kotsumi: Study & Focus Timer

A calmer way to study. Find your focus, make your planner your own, and share the journey in study rooms. Small steps, at your pace.

Turn your study plans into focused sessions. Kotsumi brings a focus timer, daily planner, personal notebooks, and shared study rooms into one calm space.

Whether you're preparing for an exam, working through homework, or building a study routine, take it one session at a time.

FIND YOUR FOCUS Choose a timed focus session with breaks, or study at your own pace with an open-ended session. Start with a task in mind and see the time you put in.

MAKE YOUR PLAN YOUR OWN Organize daily tasks and keep notes in your notebooks. Add stickers and study icons to give your planner a personal touch.

STUDY TOGETHER Join study rooms, chat with members, and take part in shared focus sessions. Optional room challenges give you another way to work toward a goal together.

SEE YOUR PROGRESS Look back on your study history, explore your statistics, and follow your streaks. Notice the sessions that add up over time.
