iPhone apps for stock monitoring

Im pretty comfortable with using bloomberg app to monitor stock until I came across shareinvestment app. There are values such as Eps and Nav all nicely calculated but I realize there is an inconsistency of PE ratio between the 2 app for the same counter.

Just wondering if the app is trustworthy and where there are different in PE ratio? There are stocks that both show same PE ratio as wel

Best method I know of is still the old-fashioned method - compute it yourself.
