Lightning app is a collection of items in the Lightning Experience which give your users access to sets of objects, tabs, and other items all in one convenient bundle in the navigation bar.
The Lightning apps can be branded with a custom color and logo. By switching between apps, the team members of the org can work more efficiently, since only the items relevant to each team are available on the navigation bar. For instance, objects such as Accounts, Contacts, Leads, Loans, Credit etc are the relevant ones for the Loan Officer app.
The navigation bar lets the users,
- Find what they need using item names for easy recognition
- Complete actions and access recent records and lists with a single click
- Personalize the navigation bar to suit the unique way they work

A→ App Launcher icon
B→ App name with custom colors and branding make each app unique and easy to identify.
C→ Users can create records and access recent records and lists directly from the navigation bar for items like Accounts, Contacts etc.

The new app has got the custom color you assigned to it and all the chosen items in the navigation bar.

- Before creating Lightning apps for your org, understand the priorities of users and know which objects and items represent their highest priorities.
- Create a master list of objects that everyone in your org wants. Then trim down the list for each group. The menus for every user group share some common objects, like Home, Tasks, Contacts, Accounts, Leads etc.
- Keep high-priority items for each group at the top and low-priority items at the bottom. Users can always go to the App Launcher to get the items they use less often.
