The Popling App
PHILADELPHIA (CBS) - On today's APP-tastic and outta SITE -- most of the time, pop-ups are super annoying. But the popling app is meant to be your friend.
You can tailor it to offer occasional pop-ups that help you learn a language, chemistry, geography or other subjects. Think of them as tiny flash cards, which can of course be turned off when necessary.
Go to Popling.net.
