A canvas app allows a designer to create an app by dragging elements on to a canvas and integrating data from multiple sources, such as SharePoint or Excel and many non-Microsoft sources. The layout of model-driven apps is determined for the user.
The new Power Apps mobile beta unifies both types of software in a single app that offers canvas and model-driven apps in a single list.
The hamburger menu in the top-left corner offers access to the slide-out sitemap, while Search and Quick Create ('+') icons are available on all pages. There are also improvements to navigations while page-level commands are on the bottom of the screen.
Users can also pin model-driven apps to an Android or iPhone home screen for a native apps-like experience.
Microsoft launched Power Apps in 2015 for business users and developers to create custom native, mobile, and web apps without writing a single line of code. The service runs on Microsoft's Azure cloud and can connect with Office 365 data via a Microsoft Graph interface.
AppSheet integrates with G Suite and Google Cloud data sources, as well as Office 365, Salesforce, Box, Dropbox, AWS DynamoDB and MySQL.
Power Apps sit within Microsoft's Power Platform, which includes Power BI and Power Virtual Agent bots. Microsoft earlier this month released a Power Platform template to help organizations responding to the COVID-19 coronavirus pandemic create their own crisis communications and collaboration app
The template app lets employees report their work status, while admins can use the app to push news and updates to an organization, as well as tap into RSS feeds.
