Mobile Monday Mid-Atlantic Demo Night tomorrow night (Monday, February 28, 5:30-8:30pm at The Hub Cira Centre). Three of them are fairly well known to the Philly area tech community; NearVerse (LoKast proximity social network), which started in Philly though I believe it may actually be based in New York now, Philly-based online ticketing service TicketLeap, and Blue Bell-based Fiberlink Communications (MaaS360 software for enterprise network "endpoint" security).
The other four are relative newcomers:
Emergensee of Wayne, has a personal security app which enables you to to instantly start streaming video from your cell phone to up to three different recipients if you feel you may be in a threatening or unsafe situation.
EverComm Technologies, which offers a service for remotely monitoring your toddlers called Keep In Touch.
MobileReactor, which has an application that allows television viewers to interact with their favorite shows, though I can't find much more information on it right now (nothing beyond a homepage is live on their website when I looked at it). Founders have backgrounds with Nokia (Traffic.com), TruePosition and Comcast; given that experience I wonder whether their app may be location-based in some way.
MyChinoki of Philadelphia allows consumers to select which local businesses they would be willing to recieve occasional SMS text messages from concerning promotions and special deals.
TicketLeap will demo its new Android ticket scanning application.
There are also followup interviews with some of last year's participating companies on Mobile Monday Mid-Atlantic's website.
Some seats are still available for the event at the time of this posting.
