How to use your phone as a PowerPoint remote
Connect your phone to the PC over Bluetooth — no software to install — then move through slides and point at what matters with the on-screen pointer. Here is the whole flow, from the first pairing to ending the show.
What you need
A Windows PC and a phone running Android 9 or later. There is nothing to install on the PC and no internet connection involved. The phone has to support Bluetooth HID Device, which most recent models do.
The presentation controls are verified for PowerPoint and Google Slides on Windows. Air Mouse additionally needs a gyroscope.
Step 1 — pair with the PC, once
Turn Bluetooth on for both the phone and the PC, then tap “Connect a new PC” in the connection area at the top of the app. The rest happens on the PC: open “Add device > Bluetooth”, pick your phone’s name from the list, and confirm when the same number appears on both screens. The connection completes on its own.
The PC treats the phone as an ordinary Bluetooth mouse and keyboard, so there are no drivers to download. You only do this once — after that, opening the app reconnects to the saved PC by itself.
Step 2 — start the slide show
With your file open on the PC, go to the “Present” tab at the bottom of the app. “Start” begins from the first slide; “From current” begins from the slide you are looking at.
The window with your slides has to be the active one on the PC. If you clicked something else a moment ago, the command goes there instead.
Step 3 — move through the slides
“Previous” and “Next” move one slide at a time, and “First” and “Last” jump to either end. If you would rather not look down at the phone, use its volume keys — volume up is always previous, volume down is always next.
Holding a volume key does not change the sound; it stays a slide command however long you press. If the buttons fall awkwardly under your thumb, switch “Presentation button side” to the left hand in Settings → Controls.
Point at the slide with the on-screen pointer
“Pointer on” places a pointer over the slide. Move it with your thumb on the large pad below to draw attention to a spot, and tap “Pointer off” when you are done. If it moves too fast or too slowly, adjust “Sensitivity” in Settings → Controls.
This is not a laser beam on the wall — it is a pointer drawn on the screen itself. Which means it is just as visible to people watching a shared screen in an online meeting.
Blank the screen, or end the show
“Black screen” hides the slide so the room looks back at you, and pressing it again (“Restore screen”) brings the slide back. When you are finished, tap “End” and the slide show closes on the PC.
“End” asks for confirmation first. That extra tap exists so a mis-press mid-presentation does not close everything.
Presenting with Google Slides? Change this first
Set “Presentation program” to Google Slides in Settings → Controls. The default is PowerPoint.
Until you switch it, “Start” and the pointer do nothing at all, because the two programs use different shortcuts. If slides advance but the show will not start, this setting is almost always the reason.
When you need the mouse mid-presentation
Playing a video or opening another window does not mean walking back to the laptop. The “Touchpad” tab moves the cursor with your fingers and handles clicks, drags, and scrolling; the “Air Mouse” tab lets you steer the cursor from across the room by moving the phone itself.
Air Mouse only works while that screen is open. It helps to leave the PC cursor where you want to start before turning it on.
That is the first run, start to finish. Every time after this, it is open the app, go to “Present”, and tap “Start”.
