App Annie's Q1 2014 Market Index report includes data from over 150 countries around the world, examining apps on both Google Play and the iOS App Store.
The weird thing (some might say the best thing) is that none of our developers caught the mistake, none of our designers caught it, none of our project managers caught it, none of our QA people caught it, and most interestingly, Apple -- with all their talk of examining apps before they let them go -- didn't catch it.
Another means of measuring China's growth comes from examining app session growth.
App search companies today often replicate the traditional search model when it comes to indexing apps – that is, they examine an app's title, metadata and description (things all input by a developer) in order to figure out what an app is and what it does.

When Android Police examined the app, they found it didn't even contain any code to do anything else.
According to Matthew Green, a cryptologist and assistant professor of computer science at Johns Hopkins University in the US who examined the app's code after being contacted by Reuters, the ByLock network generates a private security key for each device, intended to keep users anonymous.
