AppAdvisor costs a few bucks but it is a pretty slick app. The app has recommendations and with each a detailed review of the app. I've read many of their reviews for apps I already own... And I would say thery're right on. Well thought out, easy to use and provides recommendations for a ton of app genre. Well worth the couple bucks. The advise given can save potential purchasers a lot of money on apps that are later to be found to be useless, lacking, or otherwise. Two thumbs up!
