[5/5] What I think about Duolingo

I think Duolingo is a great app for learning new language languages because it’s fun, it gives you rewards for the things you do, and it also has a bit of humor involved sometimes and finally sometimes there is events that you can collect stuff from that you can only get from from the event so it’s kinda also like making sure you stay on track and you remember and that’s why I like Duolingo and I’ve been using it for a while now.

I think that Duolingo is a great app and it could teach you about all the main things. Language is math, music, and chess. I gave this a five star review because I really like it. Maybe you don’t like it but I like it.

[5/5] Duolingo

Hi! I don’t usually give reviews for apps, but I genuinely love Duolingo. It’s such a great language learning app and I’ve learned a lot. I’m currently learning Hawaiian and I think it’s so great how it teaches these endangered languages. It’s so engaging and fun because of the special events like the World Cup suits, extra XP, and getting your old streak back. The leaderboards make it fun and competitive so you don’t give up, and the streaks help you remember to do a lesson every day to improve. Although it’s a great app, I have a couple of minor complaints. I used to take Spanish on Duolingo, and there was an option to do a call with AI to help practice your speaking skills. There’s no option to do the call for learning Hawaiian. I know that it’s a way less popular language to learn, but I think it’s unfair that Duolingo only offers the call to a few languages. Another thing, is that sometimes it’s a little weird in the order that they teach you the words. Instead of learning how to

[5/5] Very good app!!

I am learning Spanish right now, and when I clicked to see the languages to choose from, there were so many!! But there is one thing I wish was different. When I’m doing lessons the battery to do them runs out so quickly, and when I see how much it costs to refill it, it’s 500 gems, and I would really like it if it was changed to maybe 200-300 gems. Anyways the app is very good and I recommend this app for all users

[5/5] Super fun!

I love this app so much, because it gives people with different backgrounds, a chance to learn something new. With a plan that is personalized towards your skill level. One tip is that there should be something like the world cup suits year round but like for different things. It motivates me more to open the app to see what outfit I got for the day!

[3/5] Make streak reminders optional

I’m paying for this app (for now). Give me the option to turn off streaks. I don’t use the app every day intentionally, and that’s not required to learn reading comprehension. The streak insistence is annoying as hell.

[3/5] Addition of beeps and clicks is annoying and distracting

The update has button press sounds for almost everything now and it distracts from the learning and sometimes you can’t hear the voices saying the words you’re supposed to be learning. Not cool duo, not cool.

[1/5] Mid

Doesn’t really show you the real meanings behind words and stuff and is just useful for some sentences. Not very immersive in the language, more about streak and leaderboard and xp than it properly learning a language. I switched to a Chinese specific app that’s way better. Duolingo kinda sucks

[4/5] GREAT but not the BEST

Duolingo helps you learn lot of languages along with an extra math course and a chess course but whatever language you pick it doesn't help you learn how to really fluently speak th language rather how to put a few sentences together and learn your basic knowledge but it doesn't cover everything so I'd reccomend Duolingo for when your starting and then once you really cover everything you think you'll need you should find another app to help you truly become fluent

[2/5] Peaked

My time is very limited and so many of the updates and changes feel designed to waste it. I had the excessive animations, e.g. the new rewards chests. I’m also not satisfied with the ability to review previous mistakes. I do like that some lessons are inserted and explain the mistakes I was making. Considering switching my family plan to another service.
