Thanks to the enormous success achieved by Samsung, Android devices are now scoring 500 million more downloads a month than iOS devices are. Android devices in the market total 900 million vs. 600 million iOS devices which means that Android downloads surpassing iOS downloads is a mathematical certainty. Each month Android devices download 2.5 billion apps as opposed to 2 billion for iOS. With the current lead Apple has, by October Android should over take iOS in total downloads of apps.
Where Android is hurting is in the number of flagship apps that remain on iOS only, or have more functionality then their Android version. Yes, Vine recently came to Android which is a big name scratched off the list. One app we've been waiting for on Android is YouTube Capture. This app allows users to upload video to Twitter, Google+, Facebook and YouTube all with one tab. Developed by Google, the app came to iOS first and an Android version is said to be in the works.
