What is Kotsumi?
Kotsumi is an iPhone study companion that brings a focus timer, daily tasks, a creative planner, study rooms, and progress tracking together. Use it for a quiet solo session or a little company while you work.
Can I use it on my own?
Of course. Your timer, tasks, notebook, and statistics work for your own study routine. Rooms, Group Focus, and challenges are there when you want to join in.
How do Kotsu Coins work?
Kotsu Coins are earned through study activity and can be used for items in the Kotsu Store. In this version, coins and digital items are not sold for real money.
Is my notebook private?
Your unpinned notebook pages stay private. You can choose to pin selected days to your profile, where visibility follows your profile settings. Read more in our Privacy Policy.
