Duolingo's free Math app arrives on iOS

Duolingo isn't just about helping people learn languages anymore. The company has released Duolingo Math on iOS, over a year after it first teased the app. Naturally, Duolingo Math shares a lot of DNA with the language apps, including colorful animations and interactive exercises in bite-sized, gamified lessons.

There are two main components to the app: an elementary-level math curriculum that goes over classroom topics and a brain-training course aimed at adults, with more advanced topics and a focus on improving mental math skills. The former covers topics such as multiplication, division, fractions, decimals, areas, geometry and measurements. The brain-training side has similar topics with tougher exercises. Duolingo hopes to help folks learn practical skills, such as converting between ounces and pounds.

Duolingo conducted a survey into math anxiety. It found that 93 percent of adults in the US have experienced some anxiety over math, while around half of high schoolers have "very high math anxiety." With its latest app, it aims to make math "accessible and fun" for everyone.

While this is far from the only math learning app around, Duolingo's name carries some weight with many folks. Like Khan Academy, Duolingo Math is free. The app is available on iPhone, iPad and some iPod Touch devices and it's only in English for now. The company hasn't revealed when it will be available on Android.
