A language course disguised as a mystery
You found a stranger's phone.
Everything in it is in
Spanish.
Lucía has been missing for 19 hours. Her sister won't stop texting. Learn just enough of the language to answer — and find out what happened to her.

found in a bin on Calle del Pez, 13:00
Not just a chat app
It's her whole phone.
Her mail, her bank, her notes, files, photos, calls and Wi-Fi history. The clue is never where you'd expect — a café's Wi-Fi network can prove where she was the night she vanished.
Screens from Case 1 · the Spanish edition
1. Read her phone
Chats, voice notes, calls, mail, notes, photos. A real phone, and every word of it in the language you're learning.
2. Tap any word
The lens tells you what that exact form means. «contestas» — you answer.
3. Prove what happened
Seal the evidence, present it in the case file. Wrong proof costs a heart.
Not a quiz.
A case.
Most apps make you pass exercises. This one hands you a phone and a problem only your new language can solve.
Real stakes
«Lucía lleva 19 horas desaparecida.»
Lucía has been missing for 19 hours.
Every day of the case starts with what's at risk. So you learn the words a real language is made of — not “the cat is on the table”, but the hard ones the story needs: missing, threat, blackmail, bribe.
“Missing”, in your language
The battery is the clock
When the phone dies, a lesson charges it.
Each visit to the phone runs on a few minutes of battery. When it dies, a short lesson charges it — built around the words you're about to need in there. Then you're straight back in.

Built to actually teach.
Words right before you need them
Every lesson pre-teaches the next part of the phone, so what you learn gets used minutes later.
A notebook that remembers
Every word you meet comes back on a spaced schedule — with the sentence you found it in.
Real slang, not textbook
People text the way they really text. jaja, mdr, ㅋㅋㅋ, www — every language laughs differently.
People who answer
Write to the characters in their language, and they react to what you wrote.
Lucía is still missing.
Your new language starts on the lock screen.
