Default snote & aircommand

after trying custom roms with builtin note 3 apps i have come to a conclusion its just a ram eater. all i want is just two apps snote and aircommand. nothing more. could some one point out to a tutorial to do so or is it already available ?

NOTE: please dont point out to flash custom rom coz i have just come from it. YES. TRIED ALL AND THEY ARE ALL RAM EATERS!
