Flashcard App Comparison: Reji vs Anki vs Quizlet

Flashcards should be a staple part of any students’ study routine. You can use them to memorize and drill anything from vocabulary to verb conjugations or lexical chunks. The trick is to stick with it and review at regular intervals so you don’t forget all that useful info. (Learn more about how our brains memorize new words and retain information, and how to harness this in my previous post here.)

The most simple flashcards have a word written in your first language on one side and the translation in your target language on the other side, but flashcards have come a long way from the homemade handwritten variety. Now, there are loads of great apps with lots of cool features which you can use to review anytime, anywhere, on the go. Much more convenient than lugging a stack of cards to the library with you.

But, which app is right for you? In this blog post, we look at the pros and cons of 3 flashcard apps – Reji, Anki, and Quizlet. Keep reading to find out more.

At A Glance – The Pros & Cons

For a quick overview, check out the table below to see the best and worst features of Reji, Anki, and Quizlet. We took into account the following factors when comparing:

  • Interface and Ease of Use: How easy to navigate is the app? Is it intuitive for users?
  • Study Modes & Games: How many different modes does it have? What types of games are available?
  • Ease of Creating Decks: How hard/time-consuming is it to make your own flashcards?
  • Built-In Spaced Repetition: Is this app a long-term memory
  • Price: How expensive is it?
  • Compatibility: Is it available online, on Android or on iOS?

We’ve outlined Spaced Repetition in a separate row because it’s super important when it comes to learning vocabulary. This is renowned method to memorize hundreds of words in a matter of weeks.

Spaced Repetition: each time you repeat information you retain it longer. All reviewed apps incorporate this method to teach you words.

It has a slick interface which is easy to navigate and very intuitive. As iDownloadBlog recently wrote about it:

The UI alone makes this worth checking out.

Saving words is a piece of cake, outshining both Anki and Quizlet. Type in your new word; Reji will translate it, look up an example sentence (to better understand the context of the word) — all by itself! It works for 48 languages.

You can easily tweak it, and the app will look up definitions, images of GIFs instead of translations. I love the silly but memorable GIFs. 

Reji automatically pulls up images and example sentences for your words, so that you can easier remember them.

So, you typed in words, the app pulled up all the data you may need for efficient memorization, now it’s time to learn.

The app has only one study mode. However, it’s pretty self-explanatory. It looks like a school test but not that boring. For each word, you see 4 options and you have to answer correctly. If you answer incorrectly, Reji will ask you to repeat this word again later (spaced repetition in action). Intervals are counted automatically, you’ll get a notification when it’s time to revise your vocab.

It will also supply you with a phonetic transcription and a text-to-speech sound bite for all of its supported 48 languages — a must-have feature for learners who want to get the pronunciation right too.

Another useful feature for language class students is sharing. Reji lets you share saved words with your fellow learners in just one tap. Me & my classmates were using it in my French class a lot — someone saved each class’s vocab and shared it across the group.

For example, here you can download a deck from my French class.

Or, a deck with Spanish curse words here.

Reji is the most affordable app of the three — it’s 100% free. Ease of use and unique features make Reji a standout. However, it’s only available on iOS.

A long-standing favorite, Anki, like Reji uses spaced repetition to help users memorize and retain information but is a little less user-friendly.

As far as its interface goes, Anki keeps things simple. It’s pretty intuitive but sometimes a little confusing. At first glance, you’re not likely to understand what a filtered deck, for example, is.

Creating a flashcard in Anki is a bit tedious — you have to look up translation or a definition you want to put on the backside yourself. Reji’s auto look up saves time in this case.

Anki has one standard study mode – card flipping. You decide how many cards you want to study per day. Then, Anki will display a word, you check if you’re correct by hitting “show answer”, and then categorize the word again, hard, good or easy which corresponds to a time interval of 10 minutes, 4 days, 7 days or 10 days when you will next be tested. Anki then keeps track of which cards need to be reviewed when so that you won’t forget any. That’s actually a pretty neat feature. But sometimes it gets a bit repetitive.

Creating a new deck in Anki is definitely more labor intensive than Reji. You’ll need to add all the info yourself, one flashcard at a time, which can be time-consuming for languages with different alphabets, characters or accents you’re not familiar with. You can make text-based cards with words or cloze passages but the cloze feature is far from intuitive. The good think about Anki is it’s highly customizable. The bad thing about Anki is, you’ll have to invest some time to learn how to customize your own flashcards.

Anki does, however, have a large database of public user-created decks to choose from which list user ratings, how many cards they have and what type of content they contain.

Anki is free for Androids but the IOS version will cost you $25 for lifetime use. You can also use the web version of Anki for free – https://apps.ankiweb.net/.

Easy to use and super intuitive, Quizlet has a range of study modes to choose from. Learn material first and then review using matching games, true or false or writing tests.  

The free version of Quizlet doesn’t use spaced repetition so it doesn’t have the same long-term focus, however, for $20 a year, you can get Quizlet plus which does. You can also add your own images and audio to your flashcards if you upgrade to the premium version.

Creating new decks of cards is straightforward but can be a little time-consuming seeing as you need to create the content for both sides of your cards. You can easily copy and paste vocab and foreign characters into new card sets without any issues. Of course, this is easier using a web browser on your computer. Quizlet will even automatically add in the audio which is a definite plus. This feature is supported by 18 different languages – not as many as Reji but not bad either.

If you can’t be bothered to make your own deck of cards, there are plenty of user-generated options to choose from but quality varies a bit so be prepared to invest a little time to find the best materials. You can easily save decks in personalized folders on your profile page.
