Is it worth paying for

Duolingo

65
Value score / 100 Worth paying? Depends It depends

Duolingo is a good free app for casual language learning and other subjects, but its aggressive monetization tactics and limitations on the free tier make the paid version questionable for serious learners.

Duolingo is highly rated for helping users learn languages, math, chess, and music, with many finding it effective and fun for basic learning R1R5R9R16. However, recent updates have introduced an 'energy' system, frequent ads, and aggressive paywall prompts that severely limit free usage and frustrate many users, making the paid subscription feel necessary for continuous learning R4R11R25R42. While some find the paid features valuable, others report bugs and a decline in quality even with a subscription R7R71R95.

Free vs paid

The free version of Duolingo allows users to learn languages, math, chess, and music . However, it is heavily restricted by an 'energy' system that limits the number of lessons you can complete before needing to wait for a recharge or watch ads R11R19R25R59. Users also experience frequent ads and constant prompts to upgrade to a paid subscription R4R13R25R42. The paid 'Super Duolingo' or 'Max' plans remove ads, offer unlimited energy or lessons, and provide additional features like flashcards R5R7R27R53. Some users report getting 'Super Family' every few months even without paying R8.

  1. [R4] 1/5 · US A once incredible idea that was monetized into ad-filled unrewarding garbage.: There has never been an update that has improved this app. Every single change just makes it harder and harder to want to keep using considering how hard they try to game you for your money. It used to be great.
  2. [R13] 4/5 · US Duolingo review: Duolingo helps me learn Spanish and German. It is very helpful and makes me feel confident speaking other languages. The only thing I don’t like is it keeps bugging me to get super and max Duolingo and it’s one so expensive and once I already say no that means no don’t keep begging me! Other than that it’s great!
  3. [R25] 2/5 · US Join super now!!: In moments between lessons, it shows you stats- “75% of learners that finish their course bought super!” While I don’t mind it, the app makes you buy ‘energy’ to actually learn every few seconds. With Ads While I do think Duolingo has helped me learn a few new words- though sometimes I forget them in my energy breaks (energy runs in 25’s, you have to watch one ad for every 5 ene
  4. [R42] 1/5 · US Not free use friendly anymore: Idk when they changed it but now even if I get answers right they just take my tries away. Every time I open the app there’s an ad telling me to pay for their subscription. After every lesson the same ad.
  5. [R11] 2/5 · US Battery life sucks: I used to love Duolingo but now they have a battery so you must rush through a lesson. Instead of being able to review and study, I have to hurry through. It takes a long time-hours for the battery to recharge. I understand they wanted your money, not really to help you learn a language.
  6. [R19] 4/5 · US Limiting but good!: I pair Duolingo with actual practice speaking and it works well for me. My biggest gripe is this new battery/energy system limits how much I can practice which seems really counterproductive. Why can’t I keep practicing?? At least before I could earn a chance to practice more…
  7. [R36] 4/5 · US A complaint: I think you should give everyone infinite battery’s but it is still a great app all and all so good on y’all
  8. [R71] 3/5 · US Didn’t notify when free trial was over!: I love using Duolingo and wanted to try the super plan. When I signed up, I selected the option to be notified before they charged for the subscription so that I could cancel it if I wanted to. However, they did not notify me and automatically charged for the annual subscription anyways.
  9. [R95] 1/5 · US Charged me during my free trial: In the middle of my 7 day free trial, I cancelled my subscription, but they still charged me the full price of the Max option, with no active subscription. Even when I first initiated the free trial, they charged me a dollar that was refunded, but it felt very sketchy. The app is just annoying in general and even with the free option there’s only so much you can do
  10. [R45] 1/5 · US Trash: It was way better when it first came. If you want to learn the basics it’s great. Anything after that, there are way better options. It’s not fun like the other reviews say anymore. A lot of ads. Expensive. Repetitive with the same phrases.
  11. [R242] 3/5 · US Overpriced: Overpriced and pisses me off because of it. Get over yourself Duolingo. Plenty of language apps out there.
  12. [R7] 1/5 · US Duo has gone Downhill: I started Duo full of enthusiasm. I have the Max plan. I paid the extra money bc I learned faster and more easily. Not anymore. My course is stuck on the same lessons repeated and Flashcard Frenzy has been using the same 10 words for 2+ weeks. That was a great learning tool to help me learn new words, get better at using them and think of them more quickly. Now it’s like thr
  13. [R125] 2/5 · US A toy for fools and a scam for gentiles: Constant nickel and diming, the microphone regularly glitches on pronunciation, and the explanation of rules also works only half the time. · translated
  14. [R1] 5/5 · US Increasing your intellect: This app is helping me learn Spanish
  15. [R5] 5/5 · US So useful and helpful: I’ve been learning German and there’s a lot of things to help you. There’s the lessons and then there’s the speed game or whatever and I love all like the prizes you can get with the gems. I currently am using the free trial of super Duolingo and it helps so much. I’ve been begging my mom for it. This is your sign to go on Duolingo and learn more of your culture just like I
  16. [R9] 5/5 · US Five stars: Duolingo is it the best app to learn different languages because if you’re new to it? and you constantly do Duolingo you start to become fluent in that language that you’re doing
  17. [R10] 5/5 · US I am Learning: The App is Helping, and I am learning, and becoming more confident
  18. [R2] 3/5 · US Chess Issue: The chess mode is fun, but the jump from 750 to 800 is like a coughing baby against nuclear bomb
  19. [R8] 4/5 · US Math: Ok so when I was doing 6th math with my kid and we got to this bit were it was like 6,8,12,14,16,18 and it was find the median which is 13 because you add 12 and 14 then you get 26 and then you divide by 2 to get 13 and I didn’t see a option for 13 and there were 6 numbers in total and so I chose the one marked 12 and it was right but the fact is there were six numbers also you do get super
  20. [R16] 4/5 · US Duolingo: It’s a great game it has math that you can learn, and you can learn all different types of languages and it fun
  21. [R20] 5/5 · US Do Duolingo has been helping do Spanish and chess and I’ve been doing really good: Duolingo helps me work on mistakes that was that I got then it helped me learn from it and it’s just been doing very good. Five stars.
  22. [R24] 5/5 · US Great game: This is a great learning game and even though I’m 9 it suits me perfectly great game
  23. [R28] 5/5 · US Very easy and simple to use: Makes learning new stuff very easy for people that are autistic and have other mental illnesses super easy for me to learn a little bit about Japanese and now I’m even playing chess because of this next I’m gonna learn music when I complete my chess course
  24. [R29] 4/5 · US Focus mode is great but: Focus mode is great but the app should allow us to define a start time. I wake up, and I’m super groggy and not mentally sharp, and to do my morning coffee and doom scroll, I have to get two lessons in. The same objective is accomplished if I can set it to turn on at noon, or later in the day. I feel like although my lesson counts are up, I’m not retaining the lessons as g
  25. [R34] 5/5 · US Fun!: The reading portion stories crack me up. They’re interesting and the vocabulary matches the unit I’m studying. I actually look forward to them! I’m annoyed with the flashcards frenzy though. I have never made it through the round that requires you to do more than 56 flashcards in 2 minutes. There doesn’t seem to be enough time, while waiting on the app to approve my answers and flip to a new
  26. [R53] 5/5 · US Love it - for the whole family: First, love that the update added photos to some of the vocab words - add more and keep that up! I’ve been using Duolingo for years. The Plus added features are worth the cost, and have rapidly increased my understanding from vocab recognition to speakable. Worth it, to me. The owl, bear, Lilly, and others make the experience fun - with each one having a unique “att
  27. [R59] 1/5 · US Energy: The new energy update is absolutely terrible! The whole app is about learning a language but once you run out of the energy you have to quit the lesson and watch an ad if you don’t have gems. And watching the ad only gives you 5 energy?! A whole lesson takes like 15, hello??? I can’t even complete a lesson anymore bro. Bring back the hearts cmon.
  28. [R27] 4/5 · US Good: Duolingo is great for learning and developing skills. It’s really helped my French and to avoid scrolling. One star is off however because it’s frustrating to run out of energy during a lesson and there are ads. (Unless you buy super Duolingo)
  29. [R21] 5/5 · US Very good: I've been learning on Duolingo for over a year and can already say a lot in different languages. Currently, I'm learning Korean, English, Chinese, Japanese, French, and chess. I always wanted to learn how to play chess but never had time, but when it's on your phone, you always find time. I switched to Duolingo even though I was learning Korean, but many languages interested me. I do, of course, attend additional English classes, but... · translated
  30. [R17] 5/5 · US Duolingo: Duolingo takes years to finish one course but it helps you learn some words. Even though it makes you speak like a robot, it’s worth trying it out.
  31. [R107] 3/5 · US Okay, not great: I downloaded Duolingo to learn Portuguese before my trip to Brazil. I always heard good things. My personal experience, Duolingo is OK for learning new vocabulary but they don’t really give you lessons. They just start throwing sentences at you and often times many new words all at once which can be overwhelming. It’s a good app but I think it could be greatly improved if they wo
  32. [R189] 3/5 · US OK, but needs work: The practice sessions are good in theory, but it gets very repetitive. It doesn’t stay up to your current level of training and gives you too much from your beginning levels
