Yeah we're much stronger on Android. This is before my time at Heyzap, but my understanding is that Heyzap on Android was initially more popular and more profitable to sell Cost-Per-Install ads for. Thus, there was a major focus on improving the Android app and the sales team was focused on selling CPI (and SDK integrations) for Android. Since we get alot of users from people who integrate our SDKs, that further boosted the Android app. So basically, this created a feedback loop where Android had many more users than the iPhone app. Indeed, the iPhone app didn't get alot of attention until recently, but in the last couple of months it (and the iOS SDKs) reached feature/design parity with the Android app. We also recently added a sales team member whose focus is on iOS developers, so if things go well we'll add many more users to iOS.
