Nowadays, the app market is flooded with options for language learners. There are flashcard apps, dictionaries, complete courses, grammar exercises, games, the list goes on… You’re sure to be spoilt for choice whatever it is you’re looking for. We shouldn’t complain, but sometimes it can feel a little overwhelming. So, how can you choose the best language learning app for you?

In this blog post, we take a look at the pros and cons of 3 popular language learning apps on the market: Reji, Memrise, and Duolingo.

At a Glance

Although Duolingo, Memrise & Reji are all language learning apps, they serve different purposes. Here’s what you need to know when it comes to choosing which one is right for you. Maybe after you’ve read this, you’ll realize 1 just isn’t enough!

  • Duolingo — best for grammar, less focus on vocabulary
  • Memrise — good for vocabulary, limited to built-in vocabulary (i.e. you can’t add your own)
  • Reji — best for learning vocabulary, highly customizable

Duolingo

Duolingo is more of a general course for language learners. If you choose Duolingo, you’ll learn grammar/syntax (how to structure sentences) and some vocabulary/expressions while you’re at it. It’s a good way to start from zero, but not the best if you already have some pre-existing knowledge of a language.

You may find Duolingo frustrating if you learn best from thorough explanations. Learning with this app is done mostly through trial and error and explanations are not offered for incorrect answers. If you are having trouble with basic sentence structures or need to drill a specific grammar point until you feel confident, Duolingo is the app for you.

Many of the sample sentences are irrelevant which can be frustrating if learning practical vocabulary and expressions is your aim. Learning how to correctly say, “A horse is eating a blue apple.” (This is a real example from the app!) may be relevant in terms of grammar but is clearly not so useful in real life situations.

Duolingo lets you learn 32 languages.

Download: On the App Store / On Google Play

Price: free

Focus: grammar, basic vocabulary

Memrise

Another popular choice, Memrise was named the overall Best App winner of the Google Play awards in 2017. Designed by a Grand Master of Memory and a neuroscientist specializing in the science of memory and forgetting, the focus of Memrise is very much so on learning new vocabulary.

For new learners, Memrise can’t compete with Duolingo when it comes to grammar. It doesn’t teach users how the language works which makes it difficult to really learn a language properly. However, if you already have a good base in your target language, Memrise is a great language learning app for quickly learning new vocabulary.

Memrise is limited to set vocabulary and courses which is a bit of shame but it’s still a solid choice for learning new vocabulary.

With Memrise, you can learn around 20 languages, depending on your mother tongue (for English speakers, it’s 21).

Download: On the App Store / On Google Play

Price: free (basic), 59.99$ (pro).

Focus: vocabulary (you can’t save your own, however).

Reji

Reji focuses exclusively on vocabulary, so while it won’t help you learn a new language from scratch it is an excellent additional resource for language learners. You could definitely use it in conjunction with another language learning app or while studying a course in-person.

The really cool thing about Reji is that it allows to build up vocabulary lists very quickly. The app translates everything for you, and also looks up an example sentence to better understand context of a new word––all by itself!

If you’re in a class, you probably need to learn up to a whopping 100 words per week. And you also probably stick to some old-school method like a notebook to write down words, their translations and then learn them by a cup of hot chocolate lying on a couch. Now imagine if you’d need only to write down a word — no more juggling between Google Translate and your notebook. That’s what Reji does.

You type in words, Reji pulls up all the data for them that will help you with memorization. Then you’re ready to start learning your new vocabulary. Reji uses Spaced Repetition, to help you memorize (and not forget!) the vocabulary you’re working on by testing you at regular intervals.

Reji supports 48 languages which is the most for apps listed here.

Download: On the App Store

Price: free

Focus: vocabulary (you can save your own).
