Hi, I'll try to be very short with question. I have in Google Play market around 5 apps that are simply picture galleries and I get now around 2.5k daily new downloads with active installs ~10%. I have airpush and admob networks in my apps that bring some minor income. I was wondering what other revenue streams could be potentially used, because getting 2.5k new users daily can't be left only with some CPC/CPM ads showing to them. Are there any good affiliate networks for mobile apps? Or maybe some popup notifications brining to my website with some offers? What could you tell from your experience or have ideas to share? Or you could share apps that are using more than ad networks. Also if you have any questions I am eager to answer you. Thank you.
