“the best tracker add on.”
Why JP343
Tracking should disappear into the background.
Most learners do not want another dashboard to maintain. They want less manual logging, fewer forgotten sessions, and a clearer sense of whether they are actually staying consistent.
整理
Cleaner data than raw stopwatch logging
Ad exclusion, blocking options, and a focused log mean the number you see actually reflects real study time.

Questions
What people usually want to know before installing
Do I need an account first?
No. The tracker works without one. A free account becomes useful when you want sync, stats, and a central progress view.
What makes this different from a generic time tracker?
JP343 is built for Japanese immersion, not generic productivity. It tracks time on YouTube, Netflix, Crunchyroll, and other streaming sites, filters ads, and shows progress in a way that makes sense for language learners.
Can I still log time manually?
Yes. Automatic tracking covers supported sites, but manual entries are still useful for podcasts, books, conversations, or anything outside the supported platforms.
Will ads or idle time inflate the totals?
The tracker skips ads automatically and only counts time when video is actually playing. The number you see stays closer to real study time.
