Power BI Desktop vs Service vs Mobile

Microsoft offers Power BI in three forms. Each form serves a different stage of the journey from raw data to shared insight. Picking the right form for each task saves time and avoids confusion.

The Restaurant Analogy

A restaurant has a kitchen, a dining hall, and a takeaway counter. Chefs create dishes in the kitchen. Guests enjoy the meal in the dining hall. Takeaway customers carry the food wherever they go. Power BI divides its work in the same way.

   KITCHEN               DINING HALL            TAKEAWAY
+--------------+      +----------------+      +-------------+
| Power BI     |      | Power BI       |      | Power BI    |
| Desktop      | ==>  | Service        | ==>  | Mobile      |
| (Build)      |      | (Share/Manage) |      | (View)      |
+--------------+      +----------------+      +-------------+

Power BI Desktop

Desktop is a free application that runs on Windows. Developers use it to connect to data, clean tables, build models, write DAX formulas, and design report pages. Desktop offers the full set of authoring tools, and files save with the .pbix extension on your computer.

Power BI Service

The Service is the cloud website where reports live after publishing. Users sign in through a web browser. The Service handles sharing, dashboards, scheduled data refresh, workspaces, apps, and security settings. Light editing of published reports works directly in the browser.

Power BI Mobile

Mobile apps exist for iOS, Android, and Windows devices. They display reports and dashboards from the Service in layouts that suit small screens. Mobile users view, filter, and receive alerts. Report building stays on Desktop.

A Typical Working Day

Arjun, a sales analyst, opens Desktop on Monday morning. He imports last week's orders, adds a measure for profit margin, and designs three report pages. He publishes the file to the Service before lunch. The sales director opens the report in a browser and applies a region filter. During a flight that evening, the director checks the same report on a phone and reads the key numbers.

Arjun (Desktop)  ---publish-->  Cloud (Service)  ---view--->  Director
                                      |                       (Browser + Phone)
                                      +--- scheduled refresh keeps data fresh

Which One Should You Learn First

Start with Desktop. Almost every skill in this series, from Power Query to DAX, lives there. A free Microsoft account type may limit Service access, so check your organization's sign-in rules before publishing. Desktop works fully offline on your own files.

Common Questions

Does Desktop work on a Mac?

Desktop runs only on Windows. Mac users open the Service in a browser or run Windows through a virtual machine.

Can I build everything in the browser?

The Service supports basic report creation, but advanced modeling and Power Query tasks need Desktop.

Does Mobile need Desktop?

Mobile reads content that someone published to the Service. Desktop only creates that content.

Key Points

• Desktop builds reports and models on a Windows computer.
• The Service shares content, schedules refresh, and manages security through the cloud.
• Mobile apps display published content on phones and tablets.
• A normal workflow moves from Desktop to Service to Mobile.
