How to Use Your Phone to Control a PowerPoint Presentation

When presenting in public, the last thing you want is to be glued to your laptop pressing keys. Knowing how to use your phone to control a PowerPoint presentation gives you freedom to move around the room, interact with the audience, and maintain eye contact. And the good news: it’s simpler than you might think.

Why use your phone as a remote control

I discovered this feature years ago and haven’t gone back to a laser pointer since. Your smartphone already has everything you need: touchscreen, connectivity, and battery to last through entire presentations.

The advantages are clear:

• Total mobility: you move around the room without restrictions.
• Next slide preview: on your phone screen you see what’s coming next, which you don’t get if you just advance with the keyboard.
• Timer control: you keep track of time without looking at a clock.
• Extra features: pen, pointer, zoom… all from your hand.

Pro-tip: Before any important presentation, do a full test. You don’t want to discover that the room’s WiFi fails right when you start.

Method 1: PowerPoint for Android/iOS (official method)

Microsoft has a built-in feature in the PowerPoint app that turns your phone into a wireless presenter. It’s the cleanest and most reliable method.

Steps to set it up

1. Install the PowerPoint app on your smartphone (Android or iOS) from the app store.
2. Open the presentation on your computer with desktop PowerPoint.
3. Connect both devices to the same WiFi network.
4. In the phone app, look for the “Present Remotely” option (there’s a presentation icon in the menu).
5. Scan the QR code that appears on your computer or enter the pairing code.
6. Done! You now control the slides from your phone.

What you can do with remote control

• Advance and go back through slides by swiping.
• See a preview of the next slide.
• Use a virtual pointer on your phone screen that appears on the projection.
• Draw on slides with the built-in pen.
• See elapsed time and presenter notes.

Requirements

• Both devices on the same WiFi network.
• Desktop PowerPoint (doesn’t work with PowerPoint Online).
• Updated PowerPoint app.

Method 2: Using a generic Bluetooth controller

If you prefer something physical, you can pair a Bluetooth controller or wireless presenter with your phone and use it as an intermediary.

Compatible professional presenters

These presenters usually come with a USB receiver you plug into the laptop. If using your phone, look for models that offer direct Bluetooth connection or a companion app.

Method 3: Using your phone as a mouse/touchpad

Another very useful option is using apps that turn your phone into a wireless touchpad for your computer. This way you control the entire desktop, not just PowerPoint.

Recommended apps

• Unified Remote: the most popular. Compatible with Windows, Mac, and Linux. Has a specific presentation mode.
• Remote Mouse: very intuitive, with big buttons to go forward and back.
• Monect: includes presentation mode and even a game controller.

How to set up Unified Remote

1. Install the Unified Remote server on your computer from unifiedremote.com.
2. Install the app on your smartphone.
3. Connect both to the same network.
4. Open the presentation and use the app’s “Presentation” mode.

This method is especially useful because it doesn’t depend on PowerPoint specifically: it works with Google Slides, Keynote, PDFs, and anything else.

Tips for a flawless presentation

I’ve been using these techniques for years and have learned some lessons the hard way:

Before presenting

• Check the room’s WiFi connection. If it’s bad, use a hotspot from your phone or a USB cable method as a backup.
• Charge your phone to 100%. A one-hour presentation uses about 5-10% of battery.
• Silence notifications. Nothing more embarrassing than a notification going off while you’re presenting.
• Close background apps that might interrupt the connection.

During the presentation

• Keep your phone screen on to see notes and the next slide.
• Use airplane mode if you don’t need WiFi for anything else (though you’ll need the network for remote control).
• Have a plan B: always carry a USB presenter receiver in case the connection fails.

Warning: Don’t rely 100% on WiFi. At conferences and events, networks tend to be saturated. Always have an alternative method ready.

Common troubleshooting

Phone won’t connect to the computer

• Verify both devices are on the same WiFi network (sometimes your phone switches to mobile data without you noticing).
• Temporarily disable the firewall to test.
• Restart the app on both devices.

There’s lag between the phone and the presentation

• Move closer to the router or connect via 5 GHz network if available.
• Close other apps consuming bandwidth.
• If it persists, switch to the USB receiver method.

I can’t see presenter notes

• In PowerPoint, go to View > Presenter View and enable it.
• In the phone app, make sure the notes viewing option is enabled.

Using your phone as a teleprompter and annotation tool

Something many presenters don’t know is that your phone can do much more than just advance slides. If you use the official PowerPoint method, your phone screen shows your presenter notes. This is pure gold when you have a long script or specific data you don’t want to forget.

But you can go further. Apps like Teleprompter Premium or BigVu let you use your phone as a teleprompter while presenting. You place the phone near the camera or on a discreet stand, and read your script without the audience noticing. This is especially useful for video recordings or streaming presentations.

You can also use PowerPoint’s built-in pen on your phone to make real-time annotations on slides. Underline key data, point out graphs, or draw arrows. Everything appears on the projection in real time. I’ve used this in workshops and the audience reaction is always positive: watching the presenter draw on the slide from their phone creates a “wow” effect that breaks the monotony.

Pro-tip: If you’re going to use the pen or virtual pointer, practice the gestures first. A pointer that appears and disappears erratically is more distracting than helpful.

Method comparison: which one to choose depending on the situation?

Not all methods work for all situations. After hundreds of presentations, here’s my quick guide:

Ideally, you should have at least two methods ready. I always carry the PowerPoint app as primary and a DinoFire USB presenter as backup. It’s saved me at least three times when the room’s WiFi died mid-presentation.

Mistakes I’ve made so you don’t have to

After years of presenting with my phone, I’ve accumulated a list of errors that cost me some awkward moments:

• Forgetting to fully silence the phone: It’s not enough to turn off the ringtone. Vibrations are also audible if the phone is on a table. Use full silent mode or place the phone face-down on a soft surface.
• Not checking the phone battery: It happened once that my phone died 10 minutes before the end. Since then, I always connect it to a power bank if the presentation exceeds 30 minutes.
• Relying on the event WiFi: Convention and hotel networks often block device-to-device communication. Always ask the organizer if the network allows mDNS or SSDP (device discovery protocols).
• Not having a backup for notes: If the phone fails, you need your notes somewhere. I keep them on a paper card in my pocket as a last resort.

Warning: Never update the PowerPoint app or your phone’s operating system the day before an important presentation. Updates can introduce unexpected changes or bugs you won’t have time to discover.

FAQ: Frequently asked questions

Can I use my phone to control PowerPoint without WiFi?

Yes, but you need alternatives. You can create a hotspot with your phone and connect the laptop to it, or use apps that work via direct Bluetooth. There are also USB receivers that create their own network.

Does it work with Google Slides or Keynote?

The official PowerPoint method only works with PowerPoint. But if you use apps like Unified Remote or Remote Mouse, they work with any presentation software because they control the entire desktop.

Can I use my Apple Watch to control PowerPoint?

Yes, the Apple Watch has a built-in PowerPoint app. It works just like the iPhone version but on your wrist, which is quite convenient if you don’t want to hold your phone.

What do I do if the connection drops mid-presentation?

Stay calm. Press the space bar or right arrow on your laptop keyboard to advance. Always keep your laptop handy as backup. You can also use a USB presenter that doesn’t depend on WiFi.

Conclusion

Knowing how to use your phone to control a PowerPoint presentation gives you a huge advantage over static presentations locked to a computer. My recommendation: start with the official PowerPoint app method, and if you present frequently, invest in Unified Remote or a Bluetooth presenter as a plan B. Once you try this, you won’t want to go back to the keyboard.
