RemotePointer is a free Android application developed by Georg Sieber in the Business & Productivity category that allows you to control your computer's keyboard and mouse using a touchpad. Additionally, you can project a digital laser pointer dot on your screen or projector, which is controlled by the movement of your Android device. This app is open source and can be downloaded on Linux, macOS, and Windows.

One of the main advantages of RemotePointer is that you can control your computer from the comfort of your couch. The laser pointer can be recorded when your screen output is being recorded during presentations, and the digital laser pointer point is more visible in bright rooms. You can simultaneously flip through slides on your Android device and control the mouse. Moreover, you can use the app as a barcode/QR code scanner for your computer.

Overall, RemotePointer is a useful and practical app that simplifies computer control and presentation management.
