This article explains how to use an Android smartphone or iPhone as a Wi-Fi mouse, remote control, and keyboard using Unified Remote, Remote Mouse, or PC Remote.
Use your phone as a wireless mouse and keyboard
Unified Remote, Remote Mouse and PC Remote apps are excellent options to turn your smartphone into a mouse for your computer. We tested each of them with an Android smartphone and a Windows PC.
All three apps are intuitive, and the mouse/touchpad functionality worked without noticeable lag on each. The keyboard functionality on Unified Remote and Remote Mouse worked fine, but we wished we could use our smartphone’s keyboard. For anyone who needs a remote or wireless mouse, we recommend one of these three apps.
Unified Remote from Unified Intents works with Windows, Mac, and Linux computers and is available in free and paid versions.
