I used AppBrain to market my Android app. They charged somewhere between 40 and 60 cents per install. The app was rising up in the Play Store for the keyword I'm targeting - 'live blackjack' - but once I stopped using AppBrain, it dropped back to an invisible #28.<p>A lot of these AppBrain installs are uninstalling it faster than they installed it. I know this kills any game's search engine position, because Google tracks retention / uninstall rates. Now, my install rate has flatlined, and my uninstall rate is looking like a hockey stick.<p>If you'd be willing to install my game and give it a try and maybe a review in the Play Store, that'd be incredibly helpful. I spent months building it all myself and hate to see it get dropped in the rankings like this.<p>https://play.google.com/store/apps/details?id=com.twansoftware.chuslivecasino&hl=en
