Useful but not complete
I find this app to be more useful than the handheld remote because the buttons are bigger and lit for use in a dark room. However despite my best efforts I cannot find the controls that move the massage unit up and down the L-track. This is critical for manual use so you can send the message to the desired place on your body. So for manual use, this app just doesn’t work. Also the selection of Bluetooth devices initially is not filtered for only infinity massage chairs, so you have to go through a long list of unneeded devices.
