Stands for "Crowdsource Reporter"
It was a system where you submit photos of incidents you captured, like fires, car crashes etc.
I've built it with Codeigniter (PHP) and mySQL. It took me about 7 months to complete it.
But I've never launched... 🙁
Actually Apple decliend it, recommending to be a webapp...
maybe someday... not sure there are any of those yet.
