Create an App

Learning Objectives

In this project, you’ll:

  • Create a Salesforce app that includes standard collaboration and analytics features.
  • Familiarize yourself with the app’s user interface in the browser and in the Salesforce mobile app.


In this project, you learn how to build an application on the Salesforce Platform from start to finish, without writing any code. If you're new to the Salesforce Platform, the goal is to introduce you to the basics of app building. These point-and-click skills apply whether or not you plan to write code on the platform. If you're familiar with the Salesforce Platform admin features—managing users and security, customizing standard objects, and so on—the goal is to apply those skills to developing new applications. 

You build a suggestion management app that allows employees to submit suggestions and track their status using these steps.

  1. Create the app definition and a data model for the application. This simple application requires only one custom object.
  2. Modify the user interface on the browser and on the Salesforce mobile app using page layouts, compact layouts, and global actions.
  3. Automate calculations, data quality, and database updates to improve the user experience using formulas, validation rules, and a process builder.
  4. Define reports, charts, and dashboards to track the status of suggestions and analyze how well the company manages suggestions.


Instead of creating a Suggestions custom object, you can use Cases, a Salesforce Service Cloud standard object. But in this example, we want to explore building a custom app without using Service Cloud.

Try Out the Mobile App

When you create an app with the Salesforce Platform, you automatically create a mobile version of the app. You can access the Salesforce mobile app in a number of ways.

  • As a downloadable mobile app (Salesforce) that you install on your phone from the Apple AppStore or Google Play
  • By navigating to using a mobile browser
  • By using the Chrome Developer Tools

For this step, we use the Chrome Developer Tools option.

  1. Open a new tab in your Chrome browser and select View > Developer > Developer Tools.
  2. To simulate your browser as a mobile device, click Toggle Device Mode.
