User reviews

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

Interesting

Very interesting app, wish there was a way to utilize it for the handicapped(blind, deaf).

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!!!!!
