android and iOS app(repost)(repost)

Hello Looking for a simple app that works with blue tooth. device A can connect to device B and B to A as well, full duplex. On the GUI or preset physical button, when the button is pressed, the same device and other device will vibrate based on the amount of times the button is pressed. If the button is pressed for a long time, the devices will vibrate for a long time. A quick press will result in a quick vibrate. 5 quick presses will result in 5 quick vibrates. As fast as you hit the button, the other device will respond. This can happen from one device to another and back and forth. The device can have a option to allow for a vibrate, light the multicolor led on the device, send text and or receive video from the connected device. So if I set on device A to light the LED to Blue, device B will emit a blue LED light and soi will the sending device. IF I press the button 2 quick times, the blue LED will blink 2 times, same results as the vibrate feature on both devices. Some sort of confirmation will be displayed or felt on the sending device to verify successful transmission.
