i think generating an address with speficic name until 5 sensitive letters on android would take an age,and so far no app for android to generate an address and generating using browser really not encouraged,but hey you can just hire someone to generate an address for you,and the one who's already trusted on this forum is shorena if i'm not mistaken

edit: seems cpfreeplz just found an app but don't sure it's working because it was last updated few years ago
