What Is Microsoft Power Apps?

What Is Microsoft Power Apps? A Plain-English Guide for Businesses

If you've ever wanted to build a custom business app without writing thousands of lines of code, Microsoft Power Apps might be exactly what you're looking for. The appeal is that it's both accessible enough for non-developers and capable enough to handle genuinely complex processes — which is a rare combination in enterprise software.

In this guide, we'll cover what Power Apps actually is, who it's for, real-world use cases, and why it's become one of the most talked-about tools in the Microsoft 365 ecosystem.

What Is Microsoft Power Apps?

Microsoft Power Apps is a low-code/no-code development platform that lets users build custom business applications without extensive coding knowledge. It's part of the Microsoft Power Platform, which also includes Power Automate, Power BI, and Power Virtual Agents.

With Power Apps, you can connect to over 400 data sources — including SharePoint, Excel, SQL Server, Dataverse, Salesforce, and more — and build fully functional apps that run on any device, desktop or mobile.

There are two main types of apps you can build:

Canvas Apps give you a blank canvas to design your app exactly how you want it, dragging and dropping components and writing simple formula-based logic, not unlike working with Excel formulas. If you need a highly customised interface, this is the approach to take.

Model-Driven Apps are built on top of Microsoft Dataverse and generate their layout automatically based on your data structure. They're ideal for complex business processes with a lot of relational data, and pair naturally with other Dynamics 365 solutions your organisation might already be using.

What Can You Actually Build With Power Apps?

This is one of the most common questions people ask — and the answer is broader than most people expect. We've covered Power Apps use cases in more detail elsewhere on the site, but here are some of the most practical real-world examples:

Expense Approval Apps. Employees submit expenses through a simple form. The app routes requests to managers for approval, updates a SharePoint list, and sends email notifications automatically — no code required. Paired with Power Automate, the entire process runs without anyone chasing anyone.

Inventory Management. Warehouse teams use barcode scanning and a canvas app to track stock levels in real time. It's a good example of how Power Apps can replace processes that have been running on spreadsheets for years, without requiring a full development project or a dedicated bespoke line of business application.

Field Inspection Apps. Engineers and inspectors complete checklists on their phones or tablets while on-site. Results are stored instantly in SharePoint or Dataverse, and reports are generated automatically — making it a natural fit for organisations already using SharePoint for document management.

Employee Onboarding. HR teams build onboarding portals that walk new starters through documents, tasks, and training materials, fully integrated with Teams and SharePoint. Combined with a broader digital transformation strategy, this kind of app can significantly improve the experience for new joiners from day one.

Power Apps and SharePoint: A Natural Pairing

The combination of Power Apps and SharePoint is one of the most popular in the Microsoft ecosystem — and for good reason. SharePoint is already widely used as a document management and collaboration platform across Microsoft 365 environments, which means the infrastructure is often already in place.

Connecting a Power Apps canvas app directly to a SharePoint list turns a standard data table into a user-friendly application. Instead of asking employees to navigate SharePoint lists directly, you give them a clean, intuitive interface that works the way they do. Common use cases include leave request systems, project trackers, asset registers, and lightweight document management workflows — all areas where the combination can deliver a significant improvement over manual or spreadsheet-based alternatives without needing a full business process management solution.

Power Apps vs Power Automate: What's the Difference?

Despite sharing half a name, Power Apps and Power Automate do very different things — and it's a distinction worth understanding before you start building.

Power Apps is about the user interface. It's what people see and interact with. Power Automate is about what happens in the background — automating repetitive tasks like sending emails, updating records, or triggering actions based on conditions. We cover this in more detail in our Power Apps vs Power Automate breakdown, but the short version is: most effective solutions use both together.

A Power Apps form collects the data; Power Automate handles the approval workflow, notifications, and record updates behind the scenes. Neither tool is a replacement for the other — they're designed to work as a pair, and both are part of the broader Microsoft Power Platform.

Is Power Apps Free?

Power Apps is included in most Microsoft 365 and Office 365 business plans, though with some limitations around data storage and advanced features. Standalone per-app and per-user plans are available for organisations with more complex requirements.

Microsoft also offers a Power Apps Developer Plan, which is completely free and gives individuals full access to build and test apps in a personal development environment — an excellent starting point for anyone who wants to explore the platform before committing to anything. If you're unsure what your current Microsoft 365 licencing already includes, that's often the first and most valuable conversation to have.

Why Power Apps Is Growing So Fast

The rise of low-code development isn't a passing trend. IT backlogs keep growing, the demand for digital tools is accelerating across every industry, and organisations need a way to bridge the gap between what their development teams can realistically deliver and what the business actually needs.

Gartner has consistently highlighted low-code platforms as among the fastest-growing segments in enterprise software. Microsoft's investment in the Power Platform has been substantial, and newer features — including AI-assisted app building through Copilot — are making it more accessible still. For businesses already embedded in the Microsoft ecosystem, Power Apps is one of the most logical extensions of the digital transformation investment they've likely already made — and one of the quickest to show a return.

Power Apps is one of the most practical tools available to businesses that want to move quickly, reduce reliance on manual processes, and build software that fits their exact needs rather than a generic template someone else designed.
