[1/5] Doesn’t self refresh.

Doesn’t self refresh. If my professor uploads something new or I join a new course, I have to sign in and out of my account multiple times to be bale to see it. I have missed assignments and almost didn’t drop a class because they simply didn’t appear on my end. Closing the app does nothing. Only thing that works SOMETIMES is signing in and out. Half the time it doesn’t even fix it.

[2/5] It was great

It was great until 90% of it was put behind a paywall. If you can find any other way to use flash cards then use it. This app will soak up your time only to lock your work behind its “plus” subscription.

[1/5] Why do I have to pay

I don’t like that I have to pay to use all the features of this app. I have used Quizlet in all my years of schooling and it really saddens me that in order to use the learn method more than once you have to pay.

[1/5] Doesn’t Work

I can’t log in. The app gives me an error page each time I try clicking on my institution, so I tried using the QR code and got an error message that way as well. I have cleared the cache as well as deleting the app entirely and redownloading to no avail. When I try clicking on the help page through the app I also get an error page. There is just no being able to use the app and I am stuck using the webpage. Edit: After reading some reviews it looks like this app just doesn’t work on the iPad after the newest update. Come on now Canvas get it together. If you have an app on the App Store then it should be usable by all devices. This is ridiculous. I should be able to use the app from my iPad without having all these issues and it should be the same for everyone else using an iPad.

[4/5] To do list change

Thank you designers for this very helpful app! I’m a college student and when I’m not on my laptop, it’s very helpful to use the app on my phone to check my “To Do” tab. However, now that school has started for me, I noticed that many features of the app are different again. I would love if the ”To Do” tab has the course name in bold again and to use the terms for the due date “Today”, “Tomorrow”, etc.

[5/5] So good super helpful

Great app! Definitely recommend. Super super helpful. However, two things. One, the screens that you see when you’re doing the lessons have too much stuff on it, making it kind of hard to focus on the lesson. I say this with every learning app, try to make the part where you actually learn more like how Duolingo makes it. Gamified to keep people learning, and simple. Other thing. PLEASE add ACT prep. I know you have SAT prep, but ACT prep would be pretty great. But, if you don’t have Khan Academy, you should definitely get it (that’s why this review is 5 stars ⭐️⭐️⭐️⭐️⭐️) ‘kay thanks for reading bye 🙂👍 A review by ThisAppIsMostlyTough

[4/5] Decent but a bit of nonsense

Teaches useless phrases more often than useful ones and despite being very gamifyed winning the contests gives measly rewards even if you get the top place of the highest trophy. Fun but can become a chore with little reward. More addicting but less effective than Rosetta Stone. If you can afford Max the AI chats are decent and short.

[1/5] Not as good as it was before

This is now the second time i quit this app, i do not like the idea of a "days done in a row" counter (streaks) the gem boxes, the constant popups about an xp boost, friend quest, "have you seen this person? nudge them too keep learning!" the quests, the leaderboards, the AI, the lives, etc. I liked it more some years ago before all of this. Goodbye you dumb green owl

You should be able to make as many mistakes as possible, and it not affect you without having to pay. The quest should not have a certain amount of time because not all of us have that time.

[1/5] Pretty Great!😊👍Please read before getting Duolingo though…

I couldn’t get Duolingo because it costed too much money, but it seems really good! The only thing is since it costed too much money, I had to delete it and when I pressed delete Duolingo on the app it said really creepily, “Getting rid of Duolingo? …You can never hide from Duo…” (Btw, Duo is the green owl mascot for the app Duolingo. )And it just scared me so bad and I immediately got rid of it. I am literally still traumatized from that! Also, Duo asked for access to my homepage and my widgets so that he can encourage me and watch me earn my daily streaks of learning. Excuse me, “Watch me”?! CREEPY ALERT!!!🚨 If you go to the App Store and look near the bottom there’s one part that will say that they use data to track you. SERIOUSLY, DUO?! Ps, if you need help getting rid of the app Duolingo you have to do some stuff in settings. It took my dad like, more than half an hour just to figure out how to delete Duolingo! I don’t know how he did it, but note; it has something to do with sett
