This is One Thing app.

Enter one tiny thing of your creative work or study into the app. Then start to focus. Before you know it, your mind will drift away. It's normal.

Now glance back at your one thing in the app and start focusing again.

Before Downloading

Please be sure to read the followings before downloading.

Use Case

The app is great for your creative work or study where you have to deal with a lot of small details. That in order to move forward, you need to take one thing and do just that before tackling another one.

Not a Traditional Todo List

You can use One Thing as a regular todo list but there will be some lacking features. For example, if you want a calendar feature where you can schedule tasks for the future, there are a lot of great apps in the App Store for that.

One Thing runs on iOS 17.0 or later, iPadOS 17.0 or later, tvOS 17.0 or later, watchOS 10.0 or later, macOS 14.0 or later, and visionOS 1.0 or later.
