Radar has gone open source!
Yes, unfortunately, I don't have time for this at all, and am working on my lil startup known as ctrleff. It is available at https://github.com/nubela/radar-phonegap for the mobile app (client), and https://github.com/nubela/radar-backend for the backend. If you like what you see, just fork it! :) Of course if you have any queries, feel free to email me at nubela [ at ] ctrleff.com with regards to anything, anything at all! Otherwise, sign yourself up for the invites list at ctrleff.com! I am hoping to launch really soon! And no, ctrleff will not be a PhoneGap app, but native apps on iOS and Android, cheers!
