Power BI Desktop vs Service vs Mobile - When to Use Which

The Big Idea

Discover how Power BI's three tools work together to save you hours and keep your data always fresh!

The Scenario

Imagine you create reports on your computer, then email files back and forth with your team, and try to view them on your phone by opening attachments. It's confusing and slow to keep track of the latest version.

The Problem

Manually sharing reports means outdated info, lost files, and lots of copying. You waste time fixing mistakes and can't easily explore data on the go or collaborate in real time.

The Solution

Power BI Desktop lets you build rich reports on your PC. Power BI Service shares and updates reports online instantly for your team. Power BI Mobile puts your data in your pocket, so you can check insights anytime, anywhere.
