Built to disappear into your study.

Every feature exists to stay out of the way. You learn; this free Japanese study tracker keeps the books.

Zero setup

Install once. It starts working the moment you visit a tracked site. No account, no config.

Smart 1-min pause

Step away from your desk, it pauses. Move the mouse, it resumes. Your hours stay honest.

Per-tab sessions

Every open tab runs its own independent clock. Open a link in a new tab without disrupting your main session.

Auto site detection

Recognizes WaniKani, BunPro, Migaku, Netflix, YouTube, and Satori Reader automatically, so reviews, reading, videos, and immersion all count as Japanese study time.

Deep analytics

Daily and weekly charts, category breakdowns, streaks, and study insights for your free Japanese learning dashboard.

Always accurate

Inactivity detection ensures your tracked hours reflect actual study time, not time spent away.

Every site. Every minute. All counted.
