I have hands on experience and have several hundreds of my own apps running live in teh Playstore and Appstore / iTunes. Feel free to contact and get your mobile apps evaluated. I will be able to get your app's icon and listing graphics updated , get your listing localized in 30+ languages, as well as take care of keyword research and targeting. ASO is something I do , day in and day out, if not for clients then for my own products, so don;t hesitate and send a message now, I will respond right away ....
