I currently use hide it pro, which is free from the play store: https://play.google.com/store/apps/d...ideitpro&hl=en
stores my files in a better directory,
can store sms/files/pictures/hides apps..etc..
can be hidden from app drawer,
can be opened by dialling a code into the phone,
has a choice of functional disguise screens...
Without screenshots, playstore link or any description, why would I choose your app? This isnt a put down on you, just curious as to what more this can offer.
