What is your app? PM me.

I’m also interested in buying it. Please write something more about it. Do you have any ads included?

ideally u should set a price of 12x of your monthly earnings when transferring an app

This app was approved by Google. Google offical apps can not run on kindle fire devices,so this app is the chief google search tool on kindle fire devices.
include amazon ads and mmedia ads.
