Planning Your App

  • Understand Your Users

First, figure out who your app is for. Are they beginners, advanced learners, or somewhere in between? What languages are they interested in, and how do they prefer to learn—videos, exercises, or games? Knowing your audience will help you create an app that feels tailored just for them.

  • Set Clear Goals

Decide what your app will focus on. Will it teach basic conversations, help users prepare for exams, or specialize in specific languages? Having a clear goal will guide the design and development process..

Deciding The Features of The App

  • User Profiles and Goals

Let users create profiles to track their progress, set daily goals, and customize their learning path.

  • Structured Lessons

Offer lessons that teach reading, writing, speaking, and listening. Use videos, audio, and interactive activities to make learning fun and effective.

  • Fun Challenges

Add elements like points, badges, and leaderboards to keep users motivated. For example, earning points for completing lessons can make the experience rewarding and enjoyable.

  • Progress Tracking

Show users how far they’ve come with visual progress bars, completed lessons, or milestones. This keeps them encouraged to continue learning.

  • Interactive Exercises

Include engaging activities like quizzes, matching games, and drag-and-drop tasks. These make learning hands-on and help users remember better.

  • Speech Practice

Use speech recognition technology so users can practice pronunciation and get immediate feedback. This is great for boosting confidence in speaking.

  • Community Features

Allow users to chat or join forums to practice conversations with others. Learning is more fun when you have someone to talk to!

  • Daily Reminders

Send gentle push notifications to remind users to complete their lessons and stick to their goals.

  • Offline Mode

Make lessons available for download so users can learn anytime, even without an internet connection.

Building the App

steps to build a language learning app

1. Research the Market

Check out popular apps like Duolingo, Babbel, or Memrise. See what they do well and where they fall short. Use these insights to create something unique.

2. Plan Your Business Model

Decide how your app will make money. Will it be a subscription-based app, have ads, or charge a one-time fee? Choose what works best for your audience.

3. Create User-Friendly Designs

Sketch out simple designs that are easy to use. Make sure the layout is clear, and users can navigate the app without confusion.

4. Pick the Right Tech

Choose reliable and secure tools for building your app. Use tech that makes your app fast and scalable as more users join.

5. Develop Quality Content

Work with language experts to create lessons that are useful, engaging, and culturally accurate. High-quality content is key to user satisfaction.

6. Decide on MVP or Full Launch

You can either launch a Minimum Viable Product (MVP) with only the basic features or go all out with a full version. Starting with an MVP lets you gather user feedback early on.

7. Test Your App

Let real users try out your app in beta testing. Gather feedback to see what’s working and what needs fixing before the official launch.

8. Plan Your Launch

Use social media, online ads, and partnerships with influencers to spread the word about your app. A strong launch strategy is essential to attract users.

9. Keep Improving

After launching, listen to user feedback to improve your app. Add new lessons and features to keep users coming back.

Marketing Your App

  • Spread the Word on Social Media: Post about your app on popular platforms to reach potential users.
  • Engage with Learning Communities: Join online groups where language learners hang out and share how your app can help them.
  • Offer Perks to New Users: Give early users discounts or free trials to encourage them to sign up.
  • Let Users Share Achievements: Add a feature for users to post their progress on social media, giving your app free publicity.

Revenue Models For Language Learning Apps

Language learning apps have become very popular, offering easy and fun ways to learn languages using technology. These apps make money in different ways, and understanding how they do it is important for anyone looking to create their own language learning app.

revenue models for language learning apps

1. Freemium Model

One of the ways language learning apps generate income is through the freemium model. Duolingo and Babbel are some examples of applications that offer the basic language learning for free while charging for more advanced functionalities like offline learning, ad removal, and other options. This approach allows people to test the application before subscribing to the paid services of the application.

2. Subscription-Based Revenue

Some apps make money by charging their users with a recurring fee such as a daily, monthly, or annual membership fee to unlock all the app’s functions. For instance, Babbel has various subscription tiers for users who wish to have more choices in learning. This model allows the app to receive constant earnings and maintain users engaged with its content.

3. In-App Purchases

A large number of applications provide in-app purchases, which means users can purchase additional content within the app, such as extra lessons, language packs, or features. It provides users with an option to select and have a unique experience; this model can be useful in maintaining user interest in the app.

4. Advertising

Some applications display ads to generate revenue, particularly for users who do not subscribe to paid versions. However, these ads must be handled very well to ensure that they do not interfere and spoil the user experience. This could mean a paid version of the app that comes without advertisements whereas a basic version is available free of charge to the users.

5. One-Time Purchases

Some applications enable users to pay a one-off fee for access to all the possibilities and content within the app for life. This is preferable for the users who do not wish to pay regularly and instead wish to pay a lump sum for all the features.

6. Collaborations and Affiliations

Language learning apps can also generate revenue through partnerships with schools or businesses that require language training for their employees. Such associations might result in volume agreements or even bespoke training packages, making additional profits.

Examples of Successful Language Learning Apps

Duolingo

Duolingo uses a mix of business models:

  • Freemium Model: Basic features are free, but users can pay for premium subscriptions (Super Duolingo) with extra benefits.
  • Advertising: Ads are shown to free users.
  • In-App Purchases: Users can buy items like “streak freezes” to keep their learning progress.
  • Language Tests: Duolingo charges a fee for its English proficiency test, adding another income stream.

Babbel

Babbel mainly uses a subscription model, offering different plans that provide access to its full range of language courses. It focuses on high-quality content, which makes it a popular choice for serious learners.

Mondly

Mondly also uses a freemium model with limited free features and a paid plan for full access. It includes in-app purchases for additional resources and offers affordable pricing, helping it attract users.
