I’ve been using Duolingo – the most popular language learning mobile app – for many years. I’m close to hitting a 6-year streak of completing at least one lesson per day, and I made a lot of progress in learning Spanish. Duolingo is free to use, but it also has a paid subscription plan, called Super Duolingo. I have never paid for Duolingo in the many years of using the app, but I was recently granted a 3 day free trial. So, I tested the additional features included in the paid plan and here is what I think. Is it worth paying for Super Duolingo?
