Ratings and Reviews

Good text reference

@robmiller

Good pocket reference for those who already have a sense for acoustics, but probably not for beginners. No calculators, text only. Surprised it's almost 7 MB for a text only app. I love supporting developers bringing acoustics apps to mobile devices though and hope the he/she continues building upon it!

Good, but...

Lacks of a better user interface. Also when I scroll down to the bottom of a page, the last ending phrase does not always show up. Please, fix this.

Thank you
