Guide · Talks & meetings

Your phone is a presentation clicker

The clicker is in the other bag. The batteries are dead. The USB dongle won't fit. You have your phone — that's enough.

What the Slides screen does

• Giant NEXT and PREV — big enough to hit without looking down.
• The volume buttons change slides (Android): phone in your pocket, thumb on the side.
• START knows the app in front: on a Mac it launches the slideshow in Keynote, PowerPoint, Google Slides or Preview with the right shortcut.
• BLACK blanks the screen when you want the room's eyes on you; END leaves the slideshow.
• A talk timer you set to the minute. It buzzes at 5 minutes, 1 minute and time-up — no need to glance at a clock.
• Need to point at something? Switch to Air and aim the phone at the screen.

Set it up before the talk

1. Install the free MouseOS app on the laptop — Mac, Windows or Linux — and allow control once.
2. Open MouseOS on the phone, on the same Wi‑Fi. Click ALLOW on the laptop. The phone remembers it.
3. Open the deck, tap START.

Conference Wi‑Fi?

Venue and hotel networks often stop devices from seeing each other. The fix works anywhere: turn on your phone's hotspot and join it from the laptop. MouseOS needs no internet — the phone and the laptop talk directly.

Works with

Anything that moves with the arrow keys: Keynote, PowerPoint, Google Slides, LibreOffice Impress, PDF viewers, reveal.js and other web decks — on a Mac, a Windows PC or a Linux laptop.
