4 stars: Excellent exercises for listening, speaking and reading Korean. The exercises are simple and repetitive enough for my slow-moving brain, and the graphics maintain visual interest. I thought of going to the Super plan, but it's more expensive than I expected. If I stick with this, I'll probably sign up for the Super plan.
4 stars: This app is really good to use when learning a new language is needed, I even learnt some extra english words from it! There is just a minor change I want to see. You know how we have those leaderboards/leagues? I wish that we could sometimes turn it off whenever we want as it feels stressful to see who has more xp while I am very busy everyday and have less time to use duolingo.
2 stars: I'm getting very frustrated after working for an hour. I see that NONE of my points earned have accumulated. In fact, they went down. It's happened many times in the past, making me drop down levels week to week. Looks like the double or tripple points calculation is not working - even though it is showing the amount before I watch all those ads. Got to fix this!
