If your percentage of correct answers exceeds 80%, you receive a pass certificate that includes a medal (illustration)! -A variety of features- ・KOTOBA LIST A mini dictionary where you can find all the vocabulary and expressions that appear in the app. Each of the words that you answered that you had remembered have a check mark next to them.

Written reviews complicate that: 75% of KanaDrills's written reviews are positive against 63% of Challenge with Erin's, so the app with the better star average is not the one people write more warmly about.
KanaDrills ships an update every 12 months, Challenge with Erin every 5 months. The most recent releases landed on October 13, 2026 and October 20, 2026 respectively.
