Kanji Teacher knows not only all the 2,136 jōyō kanjis and their readings, but also the 10,000 most common Japanese words and how to pronounce them. This unique combination enables you to learn the Kun- and On-readings of the kanjis and apply and test what you have learnt straight away: both how to read a word and how to write a word you know.

Version 14.1 · 2025-11-18
- All kanjis now come with Ulrike's Mnemonics, provided by Joy o' Kanji a site where you can find playful, informative, photo-filled essays about each of the 2,136 Joyo Kanji. - The kanji strokes have been updated with the latest data. - Scrolling on the search screen and keyboard handling have been improved, especially on iPads and when the keyboard is covering part of the screen. - A bug that slowed down the presentation under certain conditions has been fixed. - Minor adjustments have been made to the example words. Thanks to Chris and Eva for their valuable support.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
