Im an airline pilot and I use this app for pretty much every flight. The Radar, turbulence plot, metars and TAFs are the biggies. Very nice for these purposes.
What needs work:
1. I have an Iphone 5 and this thing freezes every so often and I need to reinstall it.
2. The adds are lame. I would pay $5.00 in order to get ride them.
