OneThing Support

OneThing is an iOS app that helps you process the one thing on your mind right now. You type in what matters most to you, and it gives you one sentence back.

It's not a chatbot. It's not fortune-telling. It's not a diary. It's a friend who listens to that one thing and thinks with you for a moment.
