Three steps. Five minutes.
Every day.
Every lesson follows the method of official language schools: first you learn, then you practice, and finally you use it in real sentences.
Practice
Match pairs, build sentences, listen and choose. Mistakes come back at the end so you don't forget them.
Use it
Write it, say it out loud and understand a mini story. That's how English sticks.

Cute on the outside. Serious on the inside.
What people ask us.
Do I need to know English to start?
No. If you're new, you start from "hello". If you already know some, you pick your level at the start and Kroko takes you straight to your lagoon.
How much time a day?
You choose your goal: 3, 10, 15 or 30 minutes. A lesson takes 3 to 5 minutes.
How is my pronunciation graded?
You record the sentence and the app recognizes every word you said. It gives you a percentage, marks the unclear words and explains the tricky sound (TH, V, R, the -ed…).
How far does it go?
From A1 to C2 of the Common European Framework: 27 lagoons, 135 lessons and an exam per lagoon, with a certificate for each level.
Do I need an account?
Not to start. You can create one anytime with your email, Google or Apple to keep Kroko in the cloud, and delete it from the app whenever you want.
Is the app in English or Spanish?
The explanations are written for Spanish speakers, and you can switch the interface to English or Spanish in Settings, inside the Nest.
