About

I'm a developer from the Netherlands and I build Kaizen on my own: a Pomodoro timer with Focus Rooms, where you study or work next to other people without a camera or mic. It grew out of a Discord study community I've helped run since 2022. I write the code, answer the support email and read every piece of feedback, so tell me what you think. Day to day that's React Native with Expo, Vue and Supabase.

Kaizen: Focus & Study Timer - Focus timer, app blocker and camera-free study rooms

Studying alone is the hard part, not the timer. Kaizen puts other people in the room: join a Focus Room and work alongside others as avatars with live timers, no camera or microphone. Run Pomodoro or stopwatch sessions, block distracting apps on iPhone, iPad and Android while you focus or on a schedule, and keep habits, tasks and focus stats in the same app instead of three separate ones. Free with no ads, on iPhone, iPad, Android, Windows and the web.
