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.
