I worked with a partner on this android app called 'Foogle' during HackDartmouth II. HOW IT WORKS: When you turn on this mobile app, your location will be automatically tracked and the app will find if there’s a restaurant near you and give you its menu as pop-up notification. You can click on it to get detailed view or you can just swipe the notification to ignore it.

It uses Google Maps API to track location and Parse as a backend service.

My major contribution in this gist was integrating google maps API and track location changes of the user.
