Soon I will posting the app to the Apple Store that will only have the rvThumper module in the app. The keyfob has 5 different buttons on it and is rechargeable via USB port. I might also make a separate module for the android phone.

In an update to the initial posting of rvThumper I am considering including besides vibration ... sound (any 5 sounds you can customize and record) and visual cueing (picture displayed or the button on the remote highlighted). You will be able to turn on/off any of the 3 types of output.
