Curious Ruler App

PHILADELPHIA (CBS) - On today's APP-tastic and outta SITE - Curious Ruler.

As adults, we take measurements for granted a lot of the time - but they're sometimes tough for kids to grasp. Curious Ruler helps put things in context, letting them explore and measure objects around them with side-by-side comparisons - like how many pennies big is an iPad? (It's 27, by the way.)

It's a fun educational tool that makes learning about proportions a lot easier.

Check out the Curious Ruler app.
