VNC Viewer connects your iOS or Android device to a computer running VNC-compatible server technology to allow you to take control of your at-home system even when you’re miles away. View your computer’s desktop, access your personal data, change settings, run applications, and get hold of your keyboard and mouse just as if you were sitting comfortably at your desk.

VNC Viewer has many core features. Navigating is made simple by scrolling, dragging, and selecting using standard touch, tap, and drag gestures. Mouse button mode allows precise control because you can use the left, middle, and right mouse buttons, and scroll using the mouse wheel. You can pinch to zoom in to a specific area on your computer screen, or pinch out to see the whole picture. A scrolling key bar includes buttons showing useful noncharacter computer keyboard keys, such as function, modifier, editing, and navigation keys. VNC Viewer can automatically optimize color quality and responsiveness according to your current network’s speed.

Connections from VNC Viewer to VNC-enabled computers are strong and responsive and, depending how VNC is licensed, can also be highly secure and benefit from premium features such as international keyboard support, text transfer, and enhanced performance.

VNC Viewer for Android or iOS: $4.99
