Advantages of creating a language learning app like Duolingo

Wondering if creating a language learning app is profitable? Let us address your dilemma in this section of the blog piece. Here, we have discussed the merits of launching an app like Duolingo. So go through the benefits listed below and know for yourself:

Access the rapidly growing education app economy

As evidenced by the numbers discussed above, the education & learning app market is growing at an astonishing rate. Since language learning apps are a part of this segment, launching an app like Duolingo can help you leverage the growth of this industry. It can expose your business to a profitable market and help you grow your business beyond limits.

Reach learners and customers across the globe

The best thing about online learning is that it eradicates geographical barriers and eliminates other such limitations. Once your app is launched on the popular app stores, you can make it available for learners around the globe. You can target a huge number of customers and enter markets that you never thought you could.

Make learning easy and fun for all kinds of people

As most learners today prefer smartphone-based courses, you can launch Android and iOS language learning apps and offer them ease and convenience. Give one-touch access to your platform and courses and make learning simple. Unlike traditional classrooms, each learner can set their own unique goals based on their caliber and capacity and learn at a pace that best suits them.

Earn the loyalty and trust of app-based learners

Apps inspire more customer loyalty than websites. Website users view endless SERPs (Search Engine Result Pages) and are more likely to migrate to a competitor and never return. On the other hand, an app once installed on a user’s phone is more likely to get their undivided attention and dedication. As a result, your engagement and conversions can spike up and earn you long-term loyalty and value.

Collect significant data and enhance user metrics

Native apps get access to a lot of user data. As a result, an app can help you gain more insights about your users and give you a competitive advantage. It can help you understand your customers better and collect critical data points and information. You can put that to use and make data-backed decisions to enhance your customer’s journey and get better ratings, reviews, and feedback. 

Key features of a successful language learning app

The key to a successful language learning app is the set of features and functionalities it has to offer. No matter what the niche and purpose of the app are, the features will define the user’s journey and ultimately determine the rate of engagement, conversions, retention, etc.

In short, features have the ability to make or mar the overall experience of your app. Therefore, you should be cautious about including the best and most relevant features in the app while avoiding the clutter and unnecessary elements at the same time.

Some must-haves as well as suitable features that you can include in your language learning app are as follows:

  • Easy registration, sign up & login (including login via Email, Apple, Google, etc.)
  • Tutor and learner profile creation and management
  • Easy navigation and interactive audio-visual experience
  • Intuitive search & filter for finding tutorials
  • Multiple languages to choose from
  • Clean and organized categorization of courses
  • Level-based progress tracking and monitoring
  • Reward and certification system
  • Online payment and billing management
  • Social media integration
  • Review and rating collection
  • Multilingual & localization support
  • Push notification support
  • In-app chat support
  • Ad & monetization support
  • Support for data collection and analytics

These are the elementary features of a language learning app. However, the final list will depend upon your app’s personalized goal and purpose. You can take inspiration from the list above and use it as a guide to create the final checklist of features for your app.
