I agree with you 100% on your definition of sensors, and I see that the app is about proximity as well as location.
What I'm curious about are how these "advanced proximity algorithms" and "sensor inaccuracies" can be used to locate co-users.
The only viable "sensor inaccuracy" example I can think of is network-based location. Mobile devices give lat/lon network location readings with error margins expressed as radii. Perhaps you could correlate users that are possibly close (e.g. users P and Q might be close, and are also experiencing a location error of X on the same cell carrier infrastructure, so let's strengthen their spatial relationship). Maybe it's another data point, but it's a pretty poor one.
Where this all falls down is with the notion that "GPS doesn't work" and implying that other non-positional sensors (e.g. accelerometers) can be used to get a location in the absence of GPS bearing.
Maybe I'm just missing an awesome, groundbreaking, (patented) aspect of their technology, or maybe there was some hyperbole involved in the article.
Anyways, sounds cool and I'll definitely try it if I get the chance.
