About this app: QiQi is a Bluetooth Low Energy (BLE) Shower Controller that allows you to remotely control your shower using your mobile phone or tablet device. Using the QiQi mobile app, you can remotely warm up your shower. Pressing the button in the app opens the valve and the temperature sensor inside QiQi monitors the water temperature. When the water is hot QiQi closes the valve, and then alerts you on your phone that your shower is ready. No more $$ down the drain!!
