If you were asked to name some of the most important features of your mobile device, you would probably include in your list the camera and the built-in Global Positioning System (GPS). These two features that we take for granted today are very specific to mobile development and can make your apps stand out from the crowd.

The geolocation feature enables you as a developer to identify the coordinates of your app's users—in particular, their latitude and longitude. It will also potentially save those coordinates for future use. This gives developers a huge potential: think of social networks suggesting nearby events, or travel agents recommending restaurants or hotels, or dating apps suggesting new contacts. There are so many potential scenarios to give your users relevant and personalized information!

The case for pictures is even more obvious: people love shooting and sharing their pictures. The most successful social media contain more pictures than text messages. Even the phone manufacturers base an important part of their marketing on how good their camera is. So, as developers, we should be ready to leverage this opportunity and give our users what they love, which is the ability to use their camera whenever it may add quality to your app.

And what if we put together geolocation and camera in a single app? Welcome to the Treasure Mapp!
