Founder's note
Why I built this.
Years ago, I was living in Japan and commuting by train. I found a flashcard app — nothing fancy, just kanji organized by JLPT level — and started reviewing on the ride to work. Five minutes out, five minutes back. Within a few months, something shifted. Signs I'd walked past for years started making sense. Not all of them. But enough that the city felt different. I was reading it.
Then the app disappeared from the App Store. Never updated, just gone. Every replacement I tried was either buried in features I didn't need or wanted a monthly subscription for basics. I just wanted to review kanji quickly. So I built SimplyKanji — the app I wished still existed.
