## What is Akapen?

Akapen (赤ペン, "red pen") is a Japanese keyboard for learners. Type romaji, even a little wrong, and get the right word, with red-pen marks showing exactly what you missed.

Typed byoinniikimasu? Akapen gives you 病院に行きます and marks the long vowel you dropped. It catches the mistakes learners make most:
• long vowels (gakko → 学校)
• small っ (kekon → 結婚)
• dakuten (tomotachi → 友達)
• n vs nn, particles, and slipped keys

FORGIVING CONVERSION
A full Japanese dictionary runs on your iPhone. Fuzzy matching finds the word you meant, and the last candidate is always what you typed, for names and IDs.

LEARN AS YOU TYPE
Every correction goes into your notebook, so you can review the mistakes you keep making.

ENGLISH TOO
Tap あ / EN for English input with suggestions that forgive slipped keys.

TYPE FROM YOUR COMPUTER
Connect to Deskflow on your Mac, Windows or Linux computer and type romaji on its keyboard straight into your iPhone.

PRIVATE BY DESIGN
No accounts, no analytics, no ads. Everything runs offline and what you type never leaves your device. The keyboard asks for Full Access only so it can see your App Store trial or purchase.

TRY IT FREE
Every feature keeps working. After a 7-day trial, the keyboard shows a reminder until you unlock it with a single one-time purchase. No subscription.
