Logan Square L is your private gate, and now your entry key with new eKeys feature, to your very own residence, wherever you might be. Access your Facilities Reservations, Concierge, Front Desk and Repair Requests, control Visitors Access, view and accept Deliveries, keep in touch thru our Internal Messaging System, all thru your iPhone, no matter where you are. Since Logan Square L uses GPS Localization running on the background in order to improve the accuracy of our eKeys and Beacons feature, the continued use of GPS running in the background can dramatically decrease battery life.
