We created a mobile app called World Jogger that provides runner on treadmills with a brand new visual experience by allowing them to virtually jog around any place in the world. They can also leave messages and take photos during their run. We also have a web page that allows users to check their running history and statistics. Our idea came from our own experience running on a treadmill, which is boring and tedious. We discussed with other runners and thought it would be cool if we are able to run around any place in the globe. This may sound like a dream in the beginning, but we decided to realize it using iOS development. We also utilized Google Map from the Google API and Parse from Facebook to aid in our app development.
