Canvas apps

Canvas apps are the mainstay of apps that are developed using PowerApps. They allow you to develop lightweight apps that are specifically intended for mobile devices, as well as apps that are being developed for tablet and desktop use:

Creating canvas apps is simple –  it follows the drag and drop methodology so that you can add components and position them onto the page, which gives the developer complete control of the layout. Combine this with the ability to create logic by using Excel-like functions and expressions, and you now have the ability to interact with data in a way that allows PowerApps developers of all skill levels to build functional apps.
