Step into the field.

/01
Mission‑based practice
Order under pressure. Ask for directions. Negotiate, recover, explain, persuade, and survive in another language. Scenarios include border crossings, hotel check‑ins, surveillance handoffs, market negotiations, and emergency travel moments.
/02
Private by design
The AI runs locally on your iPhone. Your voice, your practice, your progress all stay on the device. No cloud calls. No accounts. No data sent anywhere we can see it.
/03
Real‑time correction
Speak the line. Get instant feedback on pronunciation, grammar, and word choice. Mistakes turn into drills. Drills turn into reps. Reps turn into fluency.
/04
Travel cheat sheet
Thirty‑two curated phrases per language — greetings, questions, dining, directions, emergencies. It works the moment you open the app: no model loading, no signal, no AI. On a plane, in a customs line, underground. The one part that never has to wait for anything.
/05
Six languages, thirty pairs
Japanese, Mandarin, Spanish, French, English and Italian — each usable as the language you speak and the one you're learning. An Italian speaker learning Japanese gets the same app as an English speaker learning Spanish. Every competitor is English‑first. This one isn't.
/06
The model ships inside
No first‑launch download, no account, no waiting. The language model is bundled in the app — which is why it works in airplane mode on the day you install it. It is also why the download is large: that size is the feature.

It's out.
Go use it.
