To be honest, I just browse Google Play store. I'm mostly looking if the apps I have that have Pro versions are in sale, would love to buy those to support the devs.
I haven't tried it yet. I just check Google Play store once in a while if the apps I want is on sale.
What do you think about http://appnaz.com ? Have you had experience with it? I founf it yesterday and i think it is rather good with either ios and android. Maby i will try downloading something from it once
