There are two things that I hate about AppSniper
1. it doesn't have a search function, because most of the times you'll hear of an app but think it's too expensive, so you want it to track down until it drops in price..well you have to search for it throughout AppSnipper manually. Total waste of time
2. It doesn't do a good job when you are switching between screen as in you always have to start from the top to bottom when looking for an app
So I haven't used it because of that
My only solution is read blogs or websites like:
Gizmodo.com
http://theappleblog.com/
http://appshopper.com/
http://www.tuaw.com/category/iphone/
They always offer reviews or a roundup of the best apps
