Who Uses Apps to Learn a New Language?

How many languages do you speak? If you’re reading this in the U.S., chances are good that the answer is “just one.” Even though well over 90% of all American high schools offer a foreign language course, less than 1% of those who study a language in school later say they’re fluent in it.

To fill in this gap, many turn to mobile apps. Over the past few years, a number of apps have come out that enable users to learn dozens of new languages.

Who specifically uses these language apps? To find out, we turned to InMobi’s intelligence solutions, which build a holistic understanding of consumers across data sources ranging from InMobi Exchange, which reaches 1.6 billion users globally, to permissively-sourced deterministic first-party carrier data to stated feedback directly from the customers.

In particular, we looked at the following language learning apps:

  • Duolingo
  • Babbel
  • Memrise
  • Rosetta Stone

So what does the data reveal?

Insights on Top Language App Users


  • Most of the people with these mobile apps are male.
  • Close to 42% of those with the Memrise app are between the ages of 18 and 35.
  • Over 43% of people who have the Babbel app are between the ages of 26 and 65.

  • Within this space, many individuals have more than one language app on their mobile device. This does show an interest in learning languages, but it does mean that one app may not be meeting all of a user’s language acquisition needs.

How To Use This Data To Inform Your Mobile Strategy

These insights are interesting, but how can all of this information be used intelligently to further your business aims? For starters, it’s important to note the motivation people have for using these apps. Many people are probably downloading and using these apps as soon as a trip is booked or during the planning phase.

It’s also critical to understand app users demographics and where these app users often live. From a monetization perspective, it can be helpful to stress to advertisers that many app users in this space are young Non-White men living in major cities with an interest in their personal finance.
