In PowerApps, generate a three-screen app automatically to manage data in a SharePoint list, whether the site is on-premises or in the cloud.
By default, every generated app has a screen for browsing records, a screen for showing details of a record, and a screen for creating or updating records. Heuristics suggest the best layout and content for each screen, but you'll probably need to customize the app to suit your needs.
If you're unfamiliar with PowerApps, see Introduction to PowerApps.
As of this writing, PowerApps supports custom lists but not libraries. In addition, you can show data in some types of columns, such as Choice and Picture, but you can't update that data. For more information, see Known issues.
If you haven't already created a connection to SharePoint, create one.
Open PowerApps in either of these ways:
Install PowerApps Studio for Windows, open it, and then sign in using the same credentials that you used to sign up. Near the left edge, click or tap New.
Open PowerApps Studio for the web in a browser.
For a list of supported browsers and limitations in the preview release of PowerApps Studio for the web, see Create or edit apps in a browser.
Under Start with your data, click or tap Phone layout on the SharePoint tile.
Under Connect to a SharePoint site, type or paste the URL to the site that contains the list that you want to use, and then click or tap Go.
Note: Don't include a specific list in the URL.
Under Choose a list, click or tap the name of the list that you want to use.
You can sort the list names alphabetically by clicking or tapping the sort button.
You can also type or paste at least one letter in the search box to show only those list names that contain the text that you specify.
Click or tap Connect to generate the app.
If you're prompted to take the intro tour, click or tap Next to get familiar with key areas of the PowerApps interface (or click or tap Skip).
You can always take the tour later by clicking or tapping the question-mark icon near the upper-right corner and then clicking or tapping Take the intro tour.
