This project is the web redirector for SignalFlare, an app for iOS (currently) and Android (coming soon). This code is in the public domain. It's not that complex, and it's a minimalist example of getting a Sinatra app running on Heroku. The project basically consists of a Sinatra app that simply takes a simple request with encoded Latitude & Longitude and redirects the request to Google Maps. An example might make this easier to understand. Given a request like this: http://sgnl.ws/1PQXr/-325jx this app will decode that and redirect you to http://maps.google.com/maps?q=41.761957,-72.741863 That's basically it. There is a test command and a encode command as well. See the signal_parser.rb file for more details.
