Duolingo

Duolingo is the wildly popular app that allows you to learn an array of languages by taking small lessons that allow you to learn. You can use the app slowly, advancing at your own pace, and taking lessons that are as quick as five minutes a day. The app also comes with a variety of incentives and achievements, incentivizing you to learn more.

Duolingo saw a massive boost of popularity over the past year, with over 100,000,000 downloads and installs. It is very highly rated in the Google Play store, with an average rating of 4.6 out of 5 stars. 

The app is constantly being refreshed and updated, with new languages being updated on a regular basis. It also comes with an array of goals, achievements, tests, evaluations, and progress monitors. The app also really mixes up the way you learn, constantly changing the testing and method of learning. This keeps you on your toes and creates a fun and highly interactive experience that can really make the app fun to use and encourage you to keep going.

When you get right down to it, the content on this app is truly amazing. You can learn dozens of languages, at your own pace. That being said, you will have to pay to use more advanced features, and you will have to deal with in-app ads. While this is to be expected for an app like this, it can still get frustrating.
