Duolingo

Duolingo is best known as a language-learning app, but it now also features classes for math and even chess, making it a great app for making your brain work hard. Learning a new language forces you to remember words, recognize patterns, listen carefully, and recall information quickly.

The app’s strength is how easy it is to use. Lessons are short, and the streak system makes it easy to build a daily routine. You don’t need to sit down for an hour, as even a few minutes a day will make a huge difference. Of course, the more you study, the better it’ll be.

Plus, learning a new language is always in demand, whether it’s for work or a trip you’ll take in the future. The bite-sized lessons on Duolingo will help you at least start a small conversation with people in another language.

As we mentioned, Duolingo is more than just an app to learn a new language; the platform also has classes to teach you how to play chess and even play an instrument. There’s something for every brain out there.
