The RHtubs Controller App, is an app for your iOS device that allows you to access your hot tub via a direct connection anywhere in the local proximity of your tub, anywhere in your house that you can connect to your local WiFi network.

The App is the only control that works with the Roberts Hot Tubs Controller and has full functionality to set temperature, filtration cycles and to turn pumps on and off. Freeze controllers are also already built in by default.
