Natures call is a native application for Android and IOS that uses public toilet locations data from the Australian Governments data.gov.au. This data was stored in a MySQL database and could be accessed and manipulated from the native application using an API layer built in PHP.
The locations were presented as pins on Google Maps and would draw directions to that location from the users geolocation. If a pin was clicked, it would display details on that toilet. Addition functionality was added with the Facebook API to allow users to log in to provide feedback on toilet locations and rate toilets.
