Dude, this app is no bogus!

I tested it on my mom's bedroom, and then on mine: to me, both have almost exactly identical acoustics. However, Batphone was super-easily able to tell tge difference, even in complete silence! I infinitely highly recommend it!

and....

don't quite see the point of this, I thought this could be used to track other phones, location of a specific talker in your vicinity

Wondering?

I'm really confused? I've heard great things about it but what does it do? What is the actual function of it? Please advise.

Basic Instructions would be helpful !

The fact that the app doesn't come with instructions is rediculas I'm sure it would be a very clever app if I could understand the flaming thing!!!!!

The description does not explicitly state whether an internet connection is required for Batphone's core functionality. However, it relies on the device's microphone for acoustic analysis.

Can Batphone be used offline?

While the description doesn't specify offline capabilities, the core function of acoustic analysis relies on the device's microphone and pre-recorded room fingerprints, suggesting potential for offline use.

Where can I find more information about Batphone's technology?

More details about Batphone's technology can be found in the report titled "Indoor Localization without Infrastructure using the Acoustic Background Spectrum," presented at the 2011 MobiSys conference.
