I have an S3 and did my first testing of the barometer while skydiving on the weekend. I was happily surprised by how accurate it was. I'm not about to stop using a wrist mounted altimeter and rely on this alone, but being able to use my phone as an audible altimeter and not handing over $300 for a "real" audible alti makes sense to me.
