I always wanted a remote for PowerPoint that would allow me to use the phone as the laser pointer. So, I’ve made one! (macOS only, sorry)
The app serves a control page through WebSockets, that can be accessed through a phone. There’s a handy QR code to make it easy to reach the page (since it runs an open web server, there’s a token at the end to make it hard to enter if you don’t have it).
The control page gives you:
- Slide navigation.
- A laser pointer toggle.
- A touch pad that moves the Mac cursor (useful for the laser pointer).
The app is open source, and you can find it on GitHub.
