Found this the other day in the Google Play store. It is in Beta for the rest of the month and there's a feedback page on the ARRL website. It works without cell service, I used it this weekend while traveling to Moab UT, and it worked fairly well.
No idea on pricing when it comes out of beta, and it did crash once or twice on my Galaxy Note. Just informational, not trying to promote. But it looks like there aren't too many downloads, and given they haven't promoted it at all (makes sense being in public beta), figured I'd pass it along.
