Strong passwords you can actually say out loud — built from cat names — plus MeowGram: hide a secret message inside an ordinary cat photo.
A password generator and a secret cat-mail studio — broadcast with a game-show attitude.
Five candidates conjured from 1,000+ cat names, scored by Kolmogorov-style complexity. The highest score wins. Tap to copy.
EP. 01 / パスワードPaste any password for a 0–10 score and a cheeky verdict — from "a kitten could paw this open" to "fur-midably complex."
EP. 02 / スコアTuck a secret note invisibly inside an ordinary cat photo with DCT steganography. Lock it with a passphrase (ChaCha20-Poly1305) if you like.
EP. 03 / にゃんメールNo accounts, no servers, no tracking. The Android build ships without the network permission at all. Your cats keep your secrets.
EP. 04 / オフラインReal screens from the app.
Where the cats are headed next — the base app stays free; these are optional in-app purchases.
Bring your own cat. Import any photo from your library and hide your secret message inside it — not just our 100 built-in cats.
課金予定 / comingCampy parody skins that re-theme the whole show — a cold-war Kremlin-red look, a Pyongyang-broadcast look, and a tuxedo'd "00-Cat" secret-agent look. Purely for laughs.
