Power Apps vs Power Automate: Which One Do You Need?
When to use Power Apps, when to use Power Automate, and how to combine them without losing control of licences.
Key takeaways
- 01Use Power Apps when people need a screen to view, enter or approve data.
- 02Use Power Automate when a process should start from a trigger, such as a form submission, a file upload or a schedule.
- 03Most useful solutions combine both, with one shared data source such as Dataverse or SharePoint.
- 04Check the licences for each user and each flow before you design the solution, because the plan can change what you build.
Power Apps builds business apps with screens, forms and data. Power Automate builds workflows that move data and run actions between apps and services. Many processes need both: an app for people to enter or approve information, and a flow that runs in the background. Choose by the job each tool does, then check the licences each user and flow needs.
What Power Apps does
Microsoft describes Power Apps as a suite of apps, services and connectors, plus a data platform for building custom business apps. You can build canvas apps, where you design the screens, or model-driven apps, which are built around a data model and a sitemap. Apps can connect to Dataverse, SharePoint, Microsoft 365, Dynamics 365 and SQL Server, and they run in a browser or on a phone.
What Power Automate does
Microsoft describes Power Automate as a service for automating workflows between apps and services. Typical uses are synchronising files, sending notifications and collecting data. A flow can start when something happens, such as a new form entry, or run on a schedule. It does not need a screen, so it suits work that people currently do by copying data from one place to another.
Power Apps vs Power Automate at a glance
| Power Apps | Power Automate | |
|---|---|---|
| Main job | Build the screens people use to view, enter or approve data | Build workflows that move data and act between systems |
| Who sees it | Staff who open the app in a browser or on a phone | Often nobody; the flow runs in the background |
| How it starts | A person opens the app | An event, a schedule or a manual start |
| Typical example | A visit report form with a list of past visits | An alert sent when a stock level falls |
| Data | Dataverse, SharePoint, Dynamics 365, SQL Server and more | Connectors to many apps and services |
| What you build | Canvas and model-driven apps | Automated flows |
When to use Power Apps
- People need a screen with a form, a list or a dashboard.
- Users work on phones or in the field and need the same data as the office.
- The process needs a clear interface for data entry or approval.
When to use Power Automate
- A process should run without anyone opening a screen, such as copying a form response into a list.
- You need reminders, notifications or file syncs between Microsoft 365 and other tools.
- Staff move data by hand between a spreadsheet and another system, and the errors are costly.
When you need both
Take a purchase request. Staff complete a Power Apps form. A Power Automate flow then routes the request for approval, sends a reminder if it waits too long and records the decision in the same list the app reads from. Each tool does one job, and both point at the same data, so the app and the flow never disagree about a record.
Licensing and governance
Microsoft licenses Power Apps and Power Automate separately, and some connectors and premium features need a higher plan. Plans change, so check the current licence pages on the day you buy, and confirm which plan each user and each flow needs before you roll out. Microsoft's documentation says administrators create and manage environments in the Power Platform admin center. Use separate environments for development and production, and name an owner for each app and flow.
When a custom build is the better choice
Power Platform tools suit many internal processes, but a custom web or mobile app can fit better when the logic is complex, the volume is very high, or the user experience must sit far outside Microsoft 365. Ask for a written comparison of the options, including licence, support and change costs, before you commit to either route.
How Elgrith approaches Power Platform work
Our Power Apps development service covers canvas and model-driven apps, flows, environments and the change process that keeps them under control. We look at the process first, decide which parts belong in an app and which in a flow, and document the result for the people who will maintain it. We give a fixed quote after a free call.
Frequently asked questions
Do I need to write code to use Power Apps or Power Automate? Not for basic apps and flows. Microsoft's documentation also describes how developers extend the platform with code, custom connectors and client-side logic, so more complex work can use a developer.
Can Power Automate work without Power Apps? Yes. A flow can run from a trigger, such as a new email or a new file, with no app at all.
Should the app and the flow share data? Usually yes. Point both at the same table or list, so the app and the flow always agree about a record.
