The Print node allows you to debug your interactions by displaying a value on your device, separate from the UI.

You'll define the title and value that Print will display using the Expression Editor.

Titles are helpful when you're printing multiple values at once, which you can do by clicking the plus sign under the first value. Print nodes should be placed on the same interaction node as the action using the print value.

Print is great for testing and debugging, but in most situations, you won't want to share prototypes with Print enabled. If you want to display a value in your finished prototype, you can use Set Variable and Set Text actions together.
