Sort through the madness of the Google Play Store
As someone who spends a lot of their time trawling through the Google Play Store, I can tell you that there are an insane amount of apps and the majority are subpar copies of popular games that are looking to cash in.
1Mobile Market Lite provides an app catalog that sifts through Google Play apps and displays them in an easy-to-navigate menu.
There are also app suggestions from the folks at 1Mobile.
Some of the curated lists need to be updated, but overall it works as a decent way to find a new app.
