Could not get it to work at all

I read a bunch of reviews, both good and bad and was fully aware of the fact that this app really falls into the experimental category. But the idea is exceedingly cool and this particular app seemed to be the one to get. As per the authors instructions, I viewed the instructional video and read all of the documentation twice. Nonetheless, I was unable to get the app to work at all. It never gave me an accurate measurement even once. In fact, it never really gave me any measurements at all that were not just noise.

Undeterred, I read the docs again and attempted to do a manual configuration of the app. Unfortunately, if youre lucky enough to find the information on the "custom" calibration for the app, the docs are obtuse and dont really explain what the settings in question really do.

As a last resort, I contacted the author through the contact link on their website (which contains almost no information about the app itself). Its been two weeks now with no response whatsoever.

Im sure this sort of technology for the iPhone will improve over time, but at the moment neither the app or the company are ready for prime time.
