Microsoft PowerApps, formerly known as Project Siena, was originally released in 2015. PowerApps is a Software as a Service (SaaS) offering hosted by Microsoft in the cloud on the Azure platform. Most license plans for Office 365 and for Dynamics 365 include licenses for PowerApps. If you’re running Dynamics 365, in all likelihood you’re already licensed for PowerApps as well and are thereby free to use it to extend what you can do with Dynamics 365.
