Arduino Bluetooth Control of HTC

Hey

So we have developed some FSR sensors and are using a Sparkfun Bluetooth module. The idea of the project is to use an android phone as a biofeedback item. To do this the phone needs to vibrate, make noise or turn flashlight on when a certain if condition from the sensors is met. Does anyone have any suggestions for existing Bluetooth applications that will allow for this to occur?

This is an entirely Android problem. Once you have the Android app sorted, the Arduino part would be easy.
