It’s very likely that you’ve heard of Duolingo, but in case you haven’t, it’s a language learning app. You don’t always have to do little math and spelling tests to keep your brain sharp. Simply spending a few minutes a day learning a new language can also work. Unsurprisingly, Duolingo has a 4.7/5 rating from 2.5 million users. It comes with different languages to learn, so whether you want to order your next meal in Spanish or say hello in Japanese, it’s all right. The app also has new courses for learning maths and music, which is great for elementary school kids who need extra help with their lessons.
The app itself is free to download and you can take as many courses as you want in one day. However, there is a catch with the free version. If you miss five questions, you will run out of chances and have to wait until they are replenished. However, with a subscription you will have unlimited attempts, so you can spend the whole day learning the language of your choice. Subscription costs $83.99 per year or $9.99 per month.
