Series: 30 Days of Power BI | Day 2 of 30
Level: Beginner | Read time: ~7 minutes
Three products. One ecosystem. Let's clear the confusion.
If you've visited the Power BI website, you've probably noticed that "Power BI" isn't just one thing. There's a Desktop app, a web service, a mobile app — and if you're new, it's easy to wonder: which one do I actually need?
Today we answer that question clearly, so that when we install Power BI in Day 3, you know exactly what you're installing and why.
The quick answer
| Product | What you use it for | Cost |
|---|---|---|
| Power BI Desktop | Building and designing reports | Free |
| Power BI Service | Publishing, sharing, and collaborating | Free (limited) / Paid |
| Power BI Mobile | Viewing reports on your phone or tablet | Free |
Think of it like Microsoft Word and OneDrive:
- Desktop = Word (where you do the work)
- Service = OneDrive/SharePoint (where you store and share it)
- Mobile = reading a document on your phone
Most of the work in this series happens in Power BI Desktop. The other two come into play once you're ready to share your work.
Power BI Desktop — the workhorse
Power BI Desktop is a free Windows application you download and install on your computer. It's where you will spend 90% of your time as you learn.
What you can do in Desktop:
- Connect to data sources (Excel, SQL, web, APIs)
- Clean and transform data using Power Query
- Build relationships between tables
- Write DAX formulas and create measures
- Design reports with charts, tables, maps, and cards
- Format and theme your visuals
Key things to know:
- ✅ Completely free — no account required to use it
- ✅ Works offline — no internet connection needed to build reports
- ⚠️ Windows only — there is no native macOS version. Mac users can access Power BI through the browser-based Power BI Service or run Windows via a virtual machine
- ⚠️ Not for sharing — reports built in Desktop live on your machine. To share with others, you need the Service
📥 Download link: Power BI Desktop — Microsoft Store or directly from powerbi.microsoft.com
Power BI Service — the collaboration hub
Power BI Service is the browser-based platform where you publish, share, and manage your reports. You access it at app.powerbi.com — no installation required.
What you can do in the Service:
- Publish reports from Desktop to the web
- Share reports with colleagues and stakeholders
- Set up scheduled data refresh (your report updates automatically)
- Create dashboards by pinning visuals from multiple reports
- Manage workspaces for team collaboration
- Embed reports into SharePoint, Teams, or websites
- Use Power BI Copilot (AI features)
Free vs paid tiers:
| Feature | Free | Pro (paid) | Premium |
|---|---|---|---|
| Publish reports | ✅ | ✅ | ✅ |
| Share with others | ❌ | ✅ | ✅ |
| Collaborate in workspaces | ❌ | ✅ | ✅ |
| Scheduled refresh | 8x/day | 8x/day | 48x/day |
| Paginated reports | ❌ | ❌ | ✅ |
The free tier is perfect for learning. You can publish and view your own reports without paying anything. You only need Pro when you want to share reports with other people.
💡 Students and educators: Microsoft offers free Power BI Pro through Microsoft 365 Education at many universities. Check if your institution qualifies.

Power BI Mobile — reports on the go
Power BI Mobile is a free app available on iOS and Android. It connects to your Power BI Service account and lets you view reports and dashboards from your phone or tablet.
What it's good for:
- Viewing and exploring published reports on a phone
- Receiving data alerts and notifications
- Presenting dashboards in meetings from a tablet
- Annotating reports and sharing snapshots
What it's NOT good for:
- Building or editing reports (not possible on mobile)
- Replacing Desktop or Service for any analytical work
For this series, you don't need the mobile app at all. It's a viewer — useful once you're building things worth showing to others.
How the three work together
Here's a typical real-world workflow showing how the three products connect:
[Your data source]
↓
[Power BI Desktop] ← You build the report here
↓ (Publish)
[Power BI Service] ← Your team views it here
↓ (Sync)
[Power BI Mobile] ← Your manager checks it on their phone
A real-world example:
You're an analyst at an NGO. Every month, you pull a donor data CSV, clean it in Power BI Desktop, build a report showing donations by region and campaign, and publish it to the Service. Your programme director gets an email notification that the report is refreshed and opens it on their phone using the mobile app — no spreadsheet attachment needed.
What about Power BI Embedded and Report Server?
You may come across two more terms:
Power BI Embedded — for developers who want to embed Power BI visuals inside their own applications (websites, internal tools). This is an Azure product aimed at developers, not analysts.
Power BI Report Server — an on-premise version of the Service for organisations that can't store data in the cloud. Think banks, governments, or hospitals with strict data residency policies.
You won't need either of these as a beginner. They're worth knowing exist, but they're not part of this series.
What about Microsoft Fabric?
If you've been Googling Power BI recently, you've probably seen Microsoft Fabric mentioned. Fabric is Microsoft's unified analytics platform that includes Power BI alongside tools for data engineering, data warehousing, and real-time analytics.
Think of Fabric as the bigger house that Power BI now lives in. Everything you learn about Power BI in this series is fully applicable inside Fabric. If you're just starting out, focus on Power BI — you'll naturally encounter Fabric as you grow.
So, which one do you actually need right now?
For this series: Power BI Desktop only.
- ✅ Download Power BI Desktop (we do this in Day 3)
- ✅ Create a free Power BI Service account at app.powerbi.com (you'll need a work or school email — personal Gmail/Hotmail accounts aren't accepted for the free tier)
- ⏭️ Mobile app — skip it for now
⚠️ No work or school email? You can sign up for a free Microsoft 365 Developer account which gives you a work email address and access to Power BI Pro for 90 days — perfect for learning.
Key takeaways from Day 2
- ✅ Desktop is where you build reports — free, Windows-only, works offline
- ✅ Service is where you share and collaborate — browser-based, free tier available
- ✅ Mobile is for viewing reports on your phone — not needed for building
- ✅ The three products work together as a pipeline: build → publish → view
- ✅ For this series, Power BI Desktop + a free Service account is all you need
