I'm personnaly a developper and all my programs are free and open source, but I understand that the people of Groundspeak have to maintain their big database, and it costs a lot of money.
Today I'm just sad and I wanted to say. There is a lot of features in c:geo, and they are missing in the official application. I buy it a long time ago, two times (!), once on my iPhone, once on my HTC Android.
Thank you for your response IkeHurley.
