I wanted this app for 1 reason - to be able to press and hold the HOME key to open Google's Voice Search directly and not the Google Now Launcher home (whatever that view with the cards is). I can already say """"""""""""""""OK Google"""""""""""""""" from any screen - but sometimes I'd rather just have the voice prompt directly (such as when I'm around other Android phones which are all listening for """"""""""""""""OK Google""""""""""""""""!) Anyway  just wanted to say this app works perfectly for what I'm doing. I'm using a Galaxy S6 running 6.0.1 and like the instructions say you have to first set this app as your 'device assistant' which is buried in the settings. Also  I needed to change the settings in the app to auto-start the app as well (not show it in a list/menu).""
