Trigger a message to show in your mobile app when a user opens the app on their device. While you can send this message to all of a contact’s devices, it only shows on the first device that opens the app. In-app messages can’t be created in MobilePush. ![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_mobile_studio-264-0-0-production-enus/26e7f9fa-f44c-489b-9b21-135d26904a29/images/icon_note.png) Note Before you send an in-app message in Journey Builder, [create the in-app message in Content Builder](https://help.salesforce.com/s/articleView?id=mktg.mc_ceb_create_in_app.htm&language=en_US) and ask your mobile app developer to update your app to the latest MobilePush SDK (version 6.3.0 or greater). ## Full-Page and Modal Messages Full-page and modal messages force the user to dismiss or close the message and are more disruptive to the user's experience. Full-page and modal messages are best for new features, product offerings, informing the user of your use of location to increase opt-in rates, or other important messages for the user. ## Banner Messages Banner messages don’t take up as much screen space and can be swiped away (in addition to a close or dismiss button). Because of their less-disruptive nature, banners are better used for shorter messages that are lower in priority.
