## What is Koku?

Koku is a focus timer for deep work.

Focus. Rest. Repeat. Set your own session lengths or use the classic rhythm - twenty-five minutes of focus, five minutes of rest, a longer break every four sessions.

Each minute is a dot. Watch them fill.

- No accounts.
- No streaks.
- No subscriptions.

Just time, and the work in front of you.
Add Koku to your Home Screen for quick access - start, pause, and skip sessions right from the widget. Keep the timer visible on your lock screen with Live Activities. Koku also includes an Apple Watch companion app that works with the iPhone app, so you can check your timer and control sessions from your wrist.

Designed for iPhone, with an Apple Watch companion. Light and dark mode. Works in any language.
Koku (刻) is the Japanese word for a moment of time.
