PowerApps allow users to create and customize apps that connect to organizational data sources like Excel, SharePoint lists, and Dynamics 365. Apps can be generated automatically by connecting to a data source, customized from existing PowerApps templates, or built from scratch. Existing apps can be run in a web browser or downloaded onto mobile devices. Apps can also be quickly generated by selecting a SharePoint list, which will automatically build an app interface connected to that list's data.
