WAG OF THE FINGER: An FTC survey (PDF) of four hundred kids apps (200 each for Android and Apple) reveals that very few of the apps provide detail about what kind of data they collect when kids use the products. The FTC also chided Apple for saying it reviews apps--but providing little detail about what the reviews involve. Those warnings aren't really news given the recent uproar over prominent appmakers caught red-handed downloading users' address book data. (Here's a lukewarm apology from Apple.) But it's an indication again that even regulators are starting to take the category seriously. And for companies: there's some handy market info sprinkled into the report about what kinds of edtech apps exist.
