Appsfire Hot Apps and Free Apps “tries to be a portal to all things app-related,” helping you manage the apps you have while highlighting new ones. It lists top-rated and top-selling apps, and can link to your friends’ app recommendations through Facebook. (Free; Android only)
Crosswa.lk is more sophisticated in its ability to tailor recommendations to your preferences. Once you answer a few questions, it digs for suitable choices using tips from well-known commentators as well as the general public, and can tailor its picks further if you link it to your iTunes and Facebook accounts. (Free; iOS only)
Best Apps Market “contains recommendations that are more curated than those of some of its peers.” In fact, you can check it daily just to view its list of apps “tested today.” (Free; Android only)
