THE SCIENCE
In 1972, cognitive psychologists Craik and Lockhart showed that how deeply you process information determines how well you retain it. Re-reading produces shallow memory. Retrieving a character from scratch, and rating how hard it was, produces durable memory.
That's what SimplyKanji does. Every card is a retrieval attempt, not a review.

WHY KANJI FEELS IMPOSSIBLE
Most apps show you a character and expect you to memorize it cold. SimplyKanji teaches kanji the way you'll actually meet them -- inside 6,000+ real words, across all 2,400+ JLPT kanji from N5 to N1.
Miss a card and it comes back until it sticks. Get it right and your weak kanji move to the front.

HOW IT WORKS
1. Open. Tap Start. 2. Choose your JLPT level. Sequential, random, or spaced repetition. 3. Recall. Tap to reveal. Rate how well you knew it.
The app remembers what you struggle with and brings those cards back at the right time.

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. Never updated, just gone. The replacements I tried were either buried in features I didn't need or missing the simplicity that made the original work. So I built SimplyKanji -- the app I wished still existed.
