Ask HN: Review my app - Cell phone analytics for Android with Phonalyzr

This is the first version of my first Android app, which goes through your call history and displays some neat graphs. It is still basic, but I hope it'll eventually evolve into something kickass :) You can find it in the Android Market under the name "Phonalyzr" or you can visit the website here: http://www.phonalyzr.com/
