How do I start?
No account is needed. Path starts with the first group. Select one group, combine groups, or choose all 104 Hiragana readings for one continuous Challenge. Practise readings and words in Train.
Listening is unavailable or misses a reading
Allow microphone and speech access when asked. Japanese listening runs on your device and may need an initial language download. Keep background noise low and speak one clear reading. “Use choices” lets you play by tapping instead.
I cannot hear the reading voice
Raise your device’s media volume. Open the app’s Settings, check Read-aloud voice, and tap Hear the voice to preview the bundled Japanese recordings. Missed-answer corrections play even when automatic lesson reading is off.
Can I turn the music off?
Use Sound off in the story or Background music in Settings. Music pauses during Train and voice challenges. Sound effects have their own switch.
Where is my progress?
Progress stays on this device. Ninja Kana has no player account or cloud sync. Deleting the app removes its local progress; a device backup may retain a copy.
How do levels unlock?
All Hiragana training and challenges are free with unlimited play. One optional, one-time In-App Purchase unlocks Katakana training and access to Katakana and Ultimate challenges. Challenge levels also require completing the preceding level. There is no subscription. Use Restore Purchases in Settings with the same Apple Account to restore the unlock.
