So, what do you do? I'm a designer. How about you?
The 20/80 idea

Less to memorize. More you can actually say.

Most apps teach you everything a little. DoubleTilde puts the words, phrases and situations you'll use most first, then trains you until you can use them on your own.

Real-life missions

Small talk, a job interview, a phone call, a doctor's visit. Each mission is one situation you'll really face.

Speak, then try again

Record yourself, get clear feedback on what to fix first, and take another shot right away.

See what you can do

Progress shows the things you can now do in English, not points and streaks.
