HanjaroKorean Hanja, 10 a day — no lock screen takeover
1,000 characters from grade 8 to grade 4, whenever you want
Hanjaro helps you learn the 1,000 Hanja assigned to Korea's Hanja Proficiency Test, grades 8 to 4. Pick a grade and study in sets of 10 (or 5 or 20): meaning and reading, radical, stroke count and example words. Each set ends with a multiple-choice quiz, and anything you miss goes to your wrong-answer notes until you get it right.
Why people give up on Hanja apps
A Hanja screen takes over your phone the moment you turn it on
Ads pop up when you unlock, and you tap them by accident
The chunks you're asked to memorize are too big
Wrong meanings listed, so you can't trust what you learn
You just want to study when you choose to
Hanjaro never appears on your lock screen. You study only when you open the app or glance at the widget, in small sets of 5 to 20.
