Filomou

A language app where you don't study. A friend abroad calls you, in the language you're learning, at the times you said you're free.

The idea

Language apps wait for you. Filomou calls you.

People don't quit language apps because the lessons are bad. They quit because they stop opening them.

So I turned it around. Your buddy rings inside the hours you picked, and all you do is answer. Miss it and you get a message, not a guilt trip.

How a call works

Ring. Talk. Remember.

  1. Filomou, Ring

    01

    Ring

    Your buddy calls when you said you're free. It rings like a real call, even on the lock screen.

  2. Filomou, Talk

    02

    Talk

    A real conversation, out loud. Interrupt, make mistakes, tap any word you don't know.

  3. Filomou, Remember

    03

    Remember

    After the call you see what went well. Next time your buddy picks up where you left off.
