Here's an update that really should have happened a bit sooner. VNC Viewer is the official VNC client from RealVNC, the company that makes and maintains the Virtual Network Client protocol for remote computer access. Said company also makes VNC Connect, which is actually the latest version of the premium server/client program for Windows, Mac OS, Linux, and other operating systems. Version 6.0 was rebranded earlier this month, and today the Android app is compatible with the updated software. It only took almost four weeks... which isn't great for a mission critical program.
VNC Connect attempts to make the VNC protocol a little easier for the layman (and the department manager) to grasp. It includes cloud-based login options for easier remote access - no more memorizing IP addresses - plus easy direct sharing with an integrated invitation system and address book. There are also remote credential capabilities, connection nicknames, cloud sync for settings, and more technical tools for a better, smoother remote connection. Unfortunately VNC Connect is also a subscription-based service, which might turn more frugal users off. (Hint: Chrome Remote Desktop is pretty great for basic remote access, and it's free.)
There's no mention of any other changes in version 3.0.0 of the Android version of VNC Viewer, though I wouldn't be surprised to see a rebrand for the app coming soon. If you have an existing RealVNC account and you're set up with the latest version of the desktop server, simply update the Android app and log in to access your remote computers as normal.
