Your friend speaks, you answer, and it answers back without waiting for you to finish typing. It runs at the pace of a real call, which is the part that is hard to practise anywhere else.

mellow turns that around: instead of opening an app, you answer a call.
The call comes to you
Eight in the morning, seven on the way home — pick the days and the hour, and the
phone rings then. Answer and the conversation is already under way. There is no
moment left in which to decide whether today is the day.
8 languages, 19 friends
English, Japanese, Chinese, Spanish, French, German, Portuguese and Korean, each with
friends who have their own personality and way of talking.
Help in your own language
The app, in-call translations, hints and learning reports come in your language. Stuck
for words? A hint shows two things you could say next.
A real call
Voice, not typing. Your friend speaks, you answer, and it answers back without
waiting for you to finish typing. It runs at the pace of a real call, which is the
part that is hard to practise anywhere else.
Each friend talks differently
Each one talks differently. One waits while you find the word; another keeps the
pace up. Pick whoever suits the day.
Set the scene
Write the situation you want — ordering at a café, introducing yourself in an
interview — and the conversation goes there.
What you keep
A report arrives when the call ends: where you got stuck, and how the sentence
would have sounded more naturally, line by line. The corrections become review
cards, and they come back around when you are about to forget them.
Free to use
Two calls a week, five minutes each. They come back every Monday.
Subscribe if you want to talk more: no limit on calls, up to 60 minutes each.

- Version 1.0.5First seen · 2 Oct 2026
A new design puts Today, Friends, Review and Growth in one place. Start with a 60-second first hello, and a dropped call picks up where it left off if you reconnect within two minutes. Say a phrase you practised during a call and we celebrate it with you. Learning reports now score each language on its own criteria, and a scheduled call can be snoozed to later or tomorrow.
