What is Kanji Stories?
Kanji Stories is a Japanese learning app that helps you remember each kanji through memorable stories, intuitive writing practice, and smart review scheduling. It’s designed to make learning fast and enjoyable.
How is Kanji Stories different from other kanji learning apps?
Unlike rote memorization apps, Kanji Stories engages both your imagination and motor memory.
- You draw kanji to reinforce stroke order.
- You remember them through creative stories that tie meaning together.
- You review them through a probabilistic spaced repetition system (SRS) that adapts naturally. No missed reviews piling up.
What is a “probabilistic SRS”?
It’s a smarter review system inspired by how real memory works.
Instead of fixed schedules, each kanji’s chance of appearing is based on how well you know it, so that your weakest characters show up more often, and reviews never overwhelm you.
Do I need an account to start using the app?
No. You can start studying right away. Your progress is kept on the device; signing in to an account is what backs it up.
What is free, and what does premium add?
Free covers all of JLPT N5: every N5 kanji, plus the radicals and supporting characters those lessons are built from. Lessons for N4 and above are what the upgrade opens.
Premium is what the app’s own upgrade screen lists:
- Every kanji in the app, N5 through N1
- Your real study stats, not a sample
- Backup and sync on every device you sign in on
- Playlists and study filters across every kanji
- Achievements as you study (coming soon)
Your study streak and heatmap are free and always your own numbers. It is the statistics screen that shows sample data until you subscribe.
Syncing needs both premium and an account.
How many kanji does the app cover?
Over 2,000 kanji spanning JLPT N5 through N1, each with its meanings, readings and a story, together with the radicals and components they are built from.
Is Kanji Stories suitable for beginners?
Absolutely. The app introduces kanji gradually, starting with simpler characters and their building blocks (radicals). Each new kanji connects to what you’ve already learned, so you build understanding layer by layer.
Can I use the app offline?
Yes. All kanji data and your progress are stored locally for fast access.
Sync to the cloud happens when you are online, on a premium account you are signed in to.
What platforms are supported?
Kanji Stories is available on Android and iOS. Syncing between devices needs premium and the same account signed in on each.
I paid before, how do I get premium back?
Open the upgrade screen and tap Restore in the top bar. Purchases are tied to your App Store or Google Play account, so restoring works on any device signed in to the same store account. If it does not come back, write to support@fluido.llc.
How do I delete my account?
In the app: Settings → Delete account. It removes the account and erases all cloud progress. You need to be signed in for the option to be available.
