                AppBrain analyzes Android apps and games on Google Play and finds the apps that contain card.io. We provide
                free statistics on which apps and games are using these libraries, and a full list of apps can be purchased for a small fee.
                
            Using the stats below, you can answer questions like "Who's using card.io", "Which apps are a showcase for card.io", and "How popular is this library?".
About card.io usage data
Our market share and usage data is crowd-sourced. This means that we have 100% coverage of popular apps, and the less popular an app is, the more likely we won't have detected its libraries. However, this doesn't invalidate our statistics, because the power law property of app downloads means that the vast majority of all downloads is generated by a relatively small number of popular apps, which we all cover.The "related libraries" gives a good overview which code is frequently used together with card.io. These libraries may, for instance, work well together, or may be competitors to card.io.
