Guide

Invite friends

The cheapest credits you'll ever get: give the app to someone else.

How it works

1. Settings, invite friends.
2. Copy your link. It has your code in it.
3. Send it to someone who writes in a second language all day.
4. When they install and sign in you both get 50 credits, and you get 300 more when they make their first purchase.

Gifting

Same tab, gift nonolingo. You pay for a code, they redeem it, no card of theirs involved. Good for someone job hunting or moving countries.
