This app is fantastic!

I have relied on Splashtop for many years now. I can always get access from behind firewalls, from wifi and mobile data networks. My special needs son uses it for developmental games since the app supports tunnelling switch presses to the remote end. I use it for entertainment as well, video quality auto-adapts based on available bandwidth.
