Idea and implementation for the app is by me, Paul-Gabriel Müller. If you want to see more of what I create or write about, see my Apps on Google Play Store or my Blog. I used quite some resources to implement this app, here they come:

Data

All data is from the year 2016, for which the quantity of available data was just better than 2017. Following sources were used:

For agriculture and livestock data, statistics published by the Food and Agriculture Organization of the United Nations
For other stats like on economic or social causes, the Food and Agriculture Organization of the United Nations provide great and freely accessible data.

Implementation

The implementation is done in Javascript/HTML/CSS, using the framework Angular JS to get a responsive UI (which I certainly don't use perfectly, just enough to get the task done). Additionally, the following Libraries are used:

JQuery for some UI convenience
JQuery UIfor some more UI effects
Lockr to very easily persist state like username or highscore on the client. Thanks goes out to Dimitris Tsironis!
An MD5 implementation that is compatible with PHP running on the serverside. Thanks to Paul Johnston!

To be able to create APK (Android packages, the "App" files for Android) files from the couple of HTML and Javascript files, the Framework Apache Cordova is used.

For the "global highscorelist" feature, a couple of lines are implemented in the well-known LAMP stack, hosted through my webspace-account at all-inkl.com.
