Speak your life.
The language app that learns who you are before it teaches you anything.
Right now, Arbor is building a first week for…
Talk to my partner's family at gatherings and holidays.
“Mañana tengo turno de noche, pero el domingo estoy libre.”I'm on nights tomorrow, but I'm free on Sunday.
Not samples. That is the vocabulary and the sentence Arbor would build each of their first weeks from — because it asked first. Whatever you do, it starts there.
The problem
We don't teach you Spanish. We teach you your Spanish.
Every app gives everyone the same sentences, the same examples, the same coffee-shop dialogue. What actually works is the thing most people can't afford — a tutor who knows what you are learning this for, where you're going, who you need to talk to, and the conversations you are actually preparing for.
El gato bebe la leche.The cat drinks the milk.
Mañana tengo turno de noche, pero el domingo estoy libre.I'm on nights tomorrow, but I'm free on Sunday.
Inside Arbor
Open it and the decision is already made.
Why the order matters.
Most apps give you a menu and let you choose. Arbor decides, because the order you do things in changes how much of it stays with you — and almost nobody plans that for themselves.
- Review first, while the words are still worth saving.Review a word too early and you've wasted a minute. Too late and you're learning it again from scratch. Arbor tracks how quickly you forget each word and brings it back on the last day it will still stick.Spaced repetition
- Then say something out loud.Recognising a word is easy and teaches you very little. Pulling it out of your own head is hard, and that effort is what makes it stay. It's why flashcard apps feel productive and still leave you unable to hold a conversation.Active recall
- Then learn something new, just past what you can already do.Not so easy it wastes your time, not so hard it stops making sense. And built around your own life, because the words you'll actually use are the ones you remember.Comprehensible input
- Then drill it for speed.Knowing a verb ending and reaching it in under a second are two different skills. Only the fast one holds up in a real conversation, where nobody waits while you work it out.Automaticity
About 34 minutes, in the same order every day. Most people who get fluent end up building a routine like this for themselves. Arbor builds it for you, and changes it each morning based on how yesterday went.
What a lesson looks like.
Every lesson teaches one piece of grammar properly — what it is, why it works that way, and where it turns up. That part is the same for everyone, because Spanish is Spanish.
The examples are not. Every sentence you read, build and say is made from your own life — your week, your plans, and the conversations you are preparing for. A nurse learns puedo by asking to swap a shift; someone learning it for their partner's family learns the same word asking to bring something on Sunday.
It works because you remember words you have a use for. A sentence about a cat drinking milk goes in one ear. A sentence you could say to your partner's mother on Sunday does not — and every new word from the lesson goes straight into your review deck, so it comes back before you lose it.
Ninety-three lessons in Polish, seventy-two in Spanish, each written by a person and ordered so that every one rests on the last.
The rest of the app.
Four more screens you'll use every week, and what each one is for.
¿Cómo fue tu turno anoche?
Fue largo. Tuve seis pacientes.
Seis es mucho. ¿Pudiste descansar?
Un poco. Dormí en el coche.
¿En el coche? Cuéntame.
Why you'll come back
We'd rather you came back because it worked.
Most language apps keep you with guilt. Streaks you can't afford to break, notifications that tell you off, a mascot that acts hurt when you leave. It works — and it's why so many people have a 700-day streak and still can't order a coffee. Opening an app every day is easy to measure. It is not the same thing as getting better.
No streaks
Miss a Tuesday and nothing is taken away from you. Your consistency score counts the days you showed up, and never resets.
No busywork
Nothing is in the app to fill time. Every minute has a job, and you're told what that job is before you start it.
No owl
Nothing guilts you into opening the app. If you come back, it's because last time was worth it.
Measurement
We won't tell you you're B1 until you are.
Most apps hand out levels for finishing lessons. Arbor infers yours from four things it can actually observe — and where it hasn't seen enough, it says so instead of showing you a zero.
What progress feels like
Fluency isn't a level you're given. It's a moment you notice.
The first time you answer before you've translated it.
The first time you follow a conversation you weren't part of.
The first time someone hears your accent and keeps going anyway.
Nobody remembers the day they finished a lesson. They remember the first time they said something without stopping to work it out in English first. That is the day everything changes, and it is the day Arbor is built to get you to.

Spanish and Polish are built and ready. The rest open in waves — tell us yours.
