Hey guys, about two years ago, when I was still a newb when it comes to the app business, I hired a freelancer to create an application for me. The app is pretty simple, no sorcery here, some might even call it spam. I monetized the app using admob and mobilecore and made decent money with it (around 50.000). After a while, Mobilecore updated its SDK, and the old one was shut down and didn´t serve ads anymore. From that point on, I only had admob banners in my app. This still gives me, after 2 years, 10 bucks a day. Why didn´t I simply change the SDK? As I mentioned, being a newb I wasn´t aware how important the signing key of the app was. I didn´t request that key initially and never managed to get it in my hands from the freelancer I hired back then. Do you guys have any recommendations what to do with that app? How can I "squeeze" more money out of it? Thanks!
