Fullscreen in-app messages

Fullscreen messages take up the whole screen of the device! This message type is great when you really need your user’s attention, like for mandatory app updates.

Images

Fullscreen in-app messages will fill the entire height of a device and crop horizontally (left and right sides) as needed. Image and text fullscreen messages will fill 50% of the height of a device. All fullscreen in-app messages will fill the status bar on “notched” devices.

• All images must be less than 5 MB.
• We only accept PNG, JPEG, and GIF file types.
• We recommend that your images be 500 KB.

Image safe zone

When previewing a fullscreen in-app message in the Braze platform, you can enable the Image Safe Zone to the area of the message that is safe from cropping when displayed across devices. In addition to testing the Image Safe Zone in the preview pane, we recommend you test your message as always.

Larger screens

On a tablet or desktop browser, a fullscreen in-app message will sit in the center of the app screen, as shown in the following screenshot.
