Simple Switch is a simple app to control a single group of Philips Hue lights from your iOS device or your Apple Watch.

The interface is really... simple. A large toggle switch to turn the lights on and off. A vertical slider to control the brightness. A popover to allow the user to select from a few pleasing colors.

Do you need a way for visitors (babysitters, grandparents, friends) to control your Philips Hue lights without giving them your personal iOS device? If you have an older iOS device available, install Simple Switch on it and leave it for your guests to use.

Simple Switch also has support for the Thermodo and can display the temperature if the user has a Thermodo. (see http://thermodo.com)
