Microsoft Power App
Power Apps is a suite of apps, services, connectors and data platform that provides a rapid application development environment to build custom apps for your business needs. Using Power Apps, you can quickly build custom business apps that connect to your business data stored either in the underlying data platform or in various online and on-premises data sources (SharePoint, Microsoft 365, Dynamics 365, SQL Server, and so on).
Solutions Include
Solutions are used to transport apps and components from one environment to another or to apply a set of customizations to existing apps. A solution can contain one or more apps as well as other components such as site maps, tables, processes, web resources, choices, flows, and more.
Apps built using Power Apps provide rich business logic and workflow capabilities to transform your manual business processes to digital, automated processes. Further, apps built using Power Apps have a responsive design, and can run seamlessly in browser or on mobile devices (phone or tablet). Power Apps "democratizes" the custom business app building experience by enabling users to build feature-rich, custom business apps without writing code.
