App menu and App Launcher on mobile
Key Takeaway
Users switch between Lightning apps with the mobile App Launcher, and the default navigation uses the first Lightning app listed there.
In the Salesforce mobile app, users get around with a navigation menu and switch between Lightning apps with the mobile App Launcher. Admins control both from desktop Setup: the App Menu page sets the order and visibility of apps, and each Lightning app's navigation items set what appears in its mobile menu.
Getting around in the Salesforce mobile app
The Salesforce mobile app has a navigation bar at the bottom of the screen. Tapping "Menu" in that bar opens the navigation menu, where users reach all the objects, apps, and items available to them.
Users switch between apps with the mobile App Launcher, which is always available from the navigation menu. The mobile App Launcher shows the Lightning apps the admin has made available for mobile, in the same order as on desktop.
The default navigation uses the first Lightning app listed in the App Launcher, so the app order decides which app's navigation users get by default.
Switching between Salesforce accounts, such as a production account and a sandbox account, happens in the profile menu instead of the App Launcher. Users open the profile menu by tapping the profile icon at the top of the screen.
