Cell 411 is a De-centralized, micro-social platform that allows users to issue emergency alerts, and respond to alerts issued by their friends. Cell 411 is ideal for use by activists, neighborhood watches, students, friends and other groups of people willing to organize themselves independently in order to manage and respond to emergencies.

Once you and your friends download and install the app, you can create small, independent and customized cells of users to send out alerts in case of medical emergencies, police emergencies and other potential emergency situations, all in an instant. Whether your car breaks down or you are engaged in activism and need urgent help from friends, you can issue alerts with your exact GPS coordinates where your friends can get the distance and directions to your locations.

Continued use of GPS running in the background can dramatically decrease battery life.

Missing "just 411"


Why can't we have the 'old' 411 and just look up phone numbers, Unimproved, unadorned, just like it was,without all the fancy stuff, networking and threats to "officer security," etc. It now has a totally different purpose now and totally useless for me.
