Launcher App for 6.0 OS

Hi everyone-

With the newer OSs coming out, we are having a hard time finding a launcher app that will allow us to alter the appearance of the android home screen in such a way that makes it more of a data collection device (as opposed to a smartphone, ready for a barrage of apps that we would prefer data collectors to not load).

Has anyone else had any luck with apps for the Marshmallow OS that will aid in this?

Once upon a time, we used Launcher Pro and it was great!
