Drippler has been a success on Android, now available on iOS
Drippler does offer app recommendations, but overall it is essentially a news feed dedicated to apps, accessories, tips and tricks. It's a solid app that really does help to sort through the absurd number of apps that exist in both the App Store and Google Play Store (each is somewhere around 800,000 and 900,000 right now).
Drippler has an insane number of variants of its app for Android with separate apps for 39 different devices, plus the main app (we're not sure why Google hasn't asked the developer to collapse all of those listings into one, since the Play Store can simply deliver the proper variant for each device anyway.) For iOS, there is just one option for the iPhone, and no option for the iPad or iPad mini.
