I think Appbrain for Android, a free app from Switzerland’s Swiss Code Monkeys, is the app of apps in my opinion. It’s a search discovery, social and curation tool — plus a ton of extras. It helps pull the great apps you want out of the rubble of malware and other junk in the Android Market. It’s my app of the day today … and it’s free.
I like AppBrain, but stopped using it for some reason that I can’t recall. I think it’s time to get back on that horse! Thanks for the reminder, Mat!
