To use the app properly you must first have the desktop version installed on your computer. Once this is done, you have to synchronize your handset with your computer using WiFi, and synchronize the two terminals together - then you can start to use your mobile phone or tablet as a mouse and keyboard.
Remote mouse lets use your terminal like a mouse by sliding your finger across the screen, or to type on it as a keyboard. You can also use the Android terminal in both portrait and landscape, whichever you like best.
Remote Mouse is a very easy to use and lets you use your PC from a distance, especially useful if you use the computer in the living room while sitting on the couch.
