UltimatePointer

With its Mac or PC Driver counterpart, Upoint positions the cursor at the point-of-aim of the phone, combining the intuitiveness of a laserpointer and the interactivity of a mouse.
The Upoint app is designed to communicate with the UpointDriver over BlueTooth or a shared WiFi network. The iPhone app uses Augmented Reality, Motion Sensing, and other proprietary patented technologies to sense the position and orientation of the iPhone relative to the Screen. This allows the app to calculate where on the Screen the phone is pointing, and position the cursor accordingly. As such, it is the world's first interactive laserpointer. The app also features buttons for controlling PowerPoint presentations, i.e., SlideForward, SlideBack, and Blank Screen.
Just like the iPhone app, the Drivers for Mac and PC are free and can be downloaded from www.ultimatepointer.com/downloads. For more advanced modes, the iPhone app features in-app purchases (for details, see www.ultimatepointer.com).
Since Augmented Reality (AR) forms a key part of Upoint's operation, the app is most suited for more recent iPhone models that have sufficient computing power to afford a credible AR experience. The iPhone 12 Pro with its LiDAR sensor is exceptionally suited for this.
