Looking for apps to try on iPhone Duo? Start learning Japanese, explore English letter sounds with your child, or step into a playful monster classroom. These three apps have been updated for Duo.
We’re Geared Kids, and we develop all three apps featured here.

01 · JLPT N5 Step by Step
Make a little room for Japanese.
JLPT N5 Step by Step is for beginners building their Japanese foundations. Work through vocabulary, grammar and reading with clear lessons, short practice and explanations that help you understand each answer. N5 is the beginner level of the Japanese-Language Proficiency Test.
Updated for iPhone Duo, the app’s layout makes use of the screen space available for lessons and practice. Open Duo for a larger view while you study.
- Learn a concept with explanations and examples.
- Try short questions, then understand why an answer works.
- Revisit mistakes and use flashcards to review what you have learned.
Try a short session: choose a lesson, answer a few questions, then review something you found tricky. Come back to it in your next study session.
