Shall I make this? Will anyone try it?

Well I develop apps over nakststudio.com now I am thinking to design an app alternative to main gallery that will be offline (and with no video ads) and totally free, that will allow u to search directly like "I want all pics of my mumma with me without my brother" and like "design a small video transition clip for bday of my friend I have attached one of his pic" then it will go through ur gallery and do the work

So any suggestions or like improvement in core idea that you want? Also if I design it then will u try the gallery?
