Update to the beta version of Microsoft's To-Do app for Android adds dark theme and more

You'll notice that the dark theme is labeled "experimental," and some changes still need to be made. For example, the lines that separate individual items are harder (but certainly not impossible) to make out in dark theme.

Since we happen to be a beta tester for the app, we took the screenshots that you see at the top of this article. To change Microsoft's To-Do app for Android to dark theme, open the app, click on your avatar, and under General, you will see a heading that says Theme. By default, it is on light theme. Tap on "light theme" and you will see the two options available to you (light theme or dark theme).

To install the app on your Android phone, click on the sourcelink below. After you install it, you will be asked if you want to be a beta tester. Apply in the affirmative if you want to use dark theme immediately. Or, you can wait for the public version of the app to receive the feature in an upcoming update.
