Vikash Kumar has a two-parter. First up is an introduction to Power Apps:
Microsoft PowerApps is a tool within the Microsoft Power Platform suite that enables users to create custom apps without extensive coding knowledge. It’s a low-code platform that empowers both technical and non-technical users to build apps quickly. Whether you’re looking to automate business processes or solve specific problems, PowerApps provides the tools you need.
Next is a primer on Canvas Apps in Power Apps:
Canvas Apps are applications where you start with a blank canvas and design the user interface from scratch. You have complete control over the layout, appearance, and functionality of the app by dragging and dropping components onto the canvas. This makes Canvas Apps ideal for creating custom apps that match your specific design and workflow requirements.
Power Apps is something I’ve never really gotten into. I don’t think it’s extremely intuitive, which can be a drawback in a tool whose primary audience is non-developers.
