Power BI Desktop vs Service vs Mobile: Key Differences and Usage

Power BI Desktop is a Windows app for creating and designing reports with full data modeling capabilities. Power BI Service is the online platform for sharing, collaborating, and consuming reports and dashboards. Power BI Mobile is the app for viewing and interacting with reports on smartphones and tablets.

Quick Comparison

This table summarizes the main differences between Power BI Desktop, Service, and Mobile.

Feature	Power BI Desktop	Power BI Service	Power BI Mobile
Primary Use	Create and design reports	Share and collaborate reports	View and interact on mobile
Platform	Windows application	Web browser	iOS and Android apps
Data Modeling	Full data modeling and transformation	Limited modeling, mostly consumption	No modeling, only viewing
Sharing	Save files locally or publish	Share dashboards and reports with users	Access shared content
Interactivity	Design interactive visuals	Interact with reports online	Touch-friendly interaction
Offline Access	Yes, works offline	No, requires internet	Limited offline viewing

Key Differences

Power BI Desktop is the main tool for report creators. It allows you to connect to many data sources, clean and transform data, build complex data models, and design detailed reports with interactive visuals. It runs on Windows and works offline, making it ideal for deep data work.

Power BI Service is the cloud platform where you publish reports from Desktop. It focuses on sharing, collaboration, and consumption. Users can view reports, create dashboards, set up alerts, and share insights with others via a web browser. It requires internet access and supports scheduled data refreshes.

Power BI Mobile is designed for users on the go. It lets you view and interact with reports and dashboards shared via the Service. The app is optimized for touch screens and smaller displays but does not support creating or editing reports. It offers notifications and offline caching for quick access.

Code Comparison

Here is how you load data and create a simple measure in Power BI Desktop using DAX.

DAX

Sales = SUM(SalesData[Amount])

Output

A measure named 'Sales' that sums the 'Amount' column in the 'SalesData' table.

Power BI Service Equivalent

In Power BI Service, you cannot create DAX measures directly. Instead, you consume the measures created in Desktop. You can create dashboards by pinning visuals from reports.

Example of creating a dashboard tile from a report visual:

Steps (no code language)

1. Open report in Power BI Service.
2. Hover over a visual and click the pin icon.
3. Choose an existing dashboard or create a new one.
4. The visual appears as a tile on the dashboard.

Output

Dashboard tile showing the pinned visual from the report.

When to Use Which

Choose Power BI Desktop when you need to build, model, and design reports with full control over data and visuals. Use Power BI Service to share reports, collaborate with your team, and monitor data online. Opt for Power BI Mobile when you want to quickly check reports and dashboards on your phone or tablet while away from your desk.

Key Takeaways

Use Power BI Desktop for creating and modeling reports with full features.

Power BI Service is best for sharing, collaboration, and online report consumption.

Power BI Mobile is designed for viewing and interacting with reports on the go.

Desktop works offline; Service requires internet; Mobile offers limited offline access.

Measures and data modeling happen in Desktop, not in Service or Mobile.
