I need an Android app. I would like it designed and built. I want an App for Android and iOS (couldn't find both options), that will list events around my town by showing pins on a Map and by having a calendar/timeline. And I wanna have some advertising to local sponsors and users can have opportunities to win tickets for events. The app will have users registering (sign up using facebook) to see, follow, check in (if theyre on a 200m radius from the event location), create and comment about these events. Events organizers can register special accounts so they can create more events and with more visibility (enable them getting rated and the events, get statistics about people who attend their events such as age, interests and etc). Users can win tickets/duscounts to events by watching ads from our sponsors, filling surveys, and other sponsor related request.
