ALT c3nav [email protected] We're working on better indoor positioning based on UWB technology. If you would like to operate autonomous robots or similar stuff at future chaos events (including #37c3 and even #cccamp23, it might end up being more precise than GPS though we probably won't be able to cover the whole area with UWB-Beacons), stay tuned for further announcements. We will announce hardware and software requirements for using the location system once we have a working proof of concept. :)

ALT SPAM E-Mail sent to our Google play contact email. Some company wants to offer their services "improving" our app which they "admire". I'm not gonna waste your time by pasting the entire spammy Email in here. Clearly they want to charge for their services, obviously.

ALT Our reply: Hey, thanks for your initiative! I'm so happy to hear that you admire our app! What did you like the most?
