Practising a language is rarely a question of time. It is a question of starting. 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: 300 minutes a month, up to 60 minutes a call. Worth knowing Your conversation partner is an AI, not a person. Your voice and conversation are sent to OpenAI for speech recognition, conversation and learning feedback. AI replies and review expressions are sent to OpenAI or Google Gemini for speech synthesis; replies may contain your name or conversation details. The app asks for your consent before calls or scheduling. Decline and non-call features remain available. Subscription mellow Membership is a monthly or yearly auto-renewable subscription; prices are shown in the app. Payment is charged to your Apple ID account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the current period ends. Manage or cancel it in your App Store account settings.
