Because this data clearly suggests that there is a growing e-learning market in upcoming years. You will have a chance to make actual money by developing your own language learning app.

But, the question comes how to create a language learning app like Duolingo.

We at Space-O technologies have more than 10 years of experience developing various types of language learning applications. This includes education to language learning apps. After discussing with our app development team, we have mentioned the complete language learning app development process along with its timeline and cost.

Let us go through each phase one by one.

How To Create a Language Learning App Like Duolingo

The language learning mobile app Duolingo has a total of 9.6 million daily active users in 2021. If you have decided to create an app that will make a difference to learners, you can get inspired by the success of the Duolingo app. Even the mobile educational apps in the USA are helping the entire education system.

Being an experienced app development team, we have built multiple language learning applications and will help you to create your own language app too. When a client contacts us for developing a language learning app, we follow these 8 steps to convert it into a reality.

1. Decide on What are You Planning to Provide

   Having a clear idea about how you want to develop your educational mobile app is crucial. There are many educational app ideas, which will help your startup idea into reality. Planning exact functionalities and features will help you what your application will do at the functional and appearance levels.

   Each feature should be developed targeting the end-user.

   In your case, it will be new language learners. You need to consider the point of view of students and learners and develop the mobile app accordingly.

   Start by penning down your thoughts about how you want your application to look and function. Whether you want to provide foreign language courses or specific language courses. It is essential for you to be clear about why you are developing the app and who will be your target audience.

2. Find the Qualified Teachers

   Once you clearly define your goals and answer each question, the next step will be to search for qualified teachers. Discussing your app idea with a teacher will help you understand what courses to include, how to teach, and on what topic to emphasize.

   Your goal should be to offer proven educational resources and quality content to learners and gain their trust. Whatever content you upload, always focus on two-way communication with your audience.

3. Determine the App Development Platform

   Are you planning to develop a mobile application on the Android or iOS platform? In the online language learning market, the platform determines the success of your mobile app. There are over 2.3 billion Android users worldwide. The iOS users are more than 1 billion.

   The reason behind selecting the app development platform depends upon the geographic location, app development time, and development complexity as well. Also, your location matters while selecting the app development platform. Since the USA holds half of the market share of iPhones, you may choose to develop your app in iOS initially and move forward with Android later on.

4. Use the Latest Technology Stack

   You need to plan the tech stack depending upon the app development platform you have chosen. Both Android and iOS comprise different tech stacks and app development methods. Please check the table below to understand what tech stacks are used for Android and iOS.

Development Type	iOS App Development	Android App Development
Design	Storyboard XIB SwiftUI	XML
Programming Language	Swift Objective C	Java Kotlin
Toolkit	Xcode iOS SDK	Android Studio Android SDK
Dependency Management	Cocoapods Swift Package Manager	–
Database	Coredata SQLite	SQLite RealM

5. Focus on the UI/UX Part of the App

   Designing a faulty mobile application results in app uninstallation. Knowingly or unknowingly you might have uninstalled the app from your phone because of the inaccurate design. As an entrepreneur, you should know that popular language learning apps designs are heavily influenced by implementing the right design principles and rules.

   Here are some of the key components you should implement while designing mobile applications.

   The Architecture of Information

   This means providing a top-level navigation experience while accessing educational content in the mobile app. In short, adding hierarchy-wise information content defines the architecture of information.

   Interaction Design

   After the concept of the mobile app is final, the next step is to design an app conceptually. It includes icons, fonts, images, and aesthetics.

   Usability

   Does the app provide the exact information a user wants? Usability helps users to find the exact information they want.

   Wireframe

   The wireframe is about designing an app sample to determine how the app will work. You can test the look and feel of the app before getting it live for the public.

   Visual Design

   Whenever the user interacts with an application, they check many elements from icons, colors to images and fonts. But the main thing is how the app is offering a unique appearance to users and stands out from the crowd.

6. Develop a Language Learning Application

   After implementing the design and planning out the content, the next step will be to develop a fully functional language learning application. In case, if you are short of budget, you may go for the MVP version of the mobile app development too.

   Initially, offering a free language learning subscription will help you to get initial users to your mobile app. We have helped one of our clients to develop an educational app to learn Japanese where students can count objects in the Japanese language. Let’s discuss the app development session.

   The app development session will be divided into 2 parts.

   • Front-end App Development
   • Back-end App Development

   Front-end App Development

   After completing the pre-design stage, the app goes into the front-end app development. The approved design will be later built into a complete app design. Mainly the front-end app development technologies include HTML, CSS, and JavaScript.

   Back-end App Development

   Back-end app development includes all the processes. Whenever you type a request in the browser, the request will reach where the algorithm processes the data and gives you the specific output. Different technologies like PHP, Python, Laravel are used for backend development.

   One thing to note here, only implementing front and back end development alone won’t help your app to succeed. It is gamification that will make your application usable.

   Education apps use gamification to offer an enhanced learning process to users. Learning a new language is hard, but gamification makes it easier by allowing users to offer a game-like experience.

   For example, Duolingo allows you to compete against other learners, offers leaderboards, leagues, experience points (XP), progress bars to help you experience that you are directly competing against another human being via the app.

7. Test Your Application

   Once your mobile app is built, you should test it for bugs and make your application error-free before launching it for the public. It is the initial stage of app development, QA will introduce you to the weaknesses and loopholes of the application.

   You have the option to develop the complete app with essential features and test it with QA to find the defects in the mobile app. Without solving each bug and issue, you should not move forward with the launching of the mobile application. Because uploading an app with errors will result in failure.

8. Launch and Market Your App

   After successfully testing the mobile app, it is time to launch your language learning application. However, launching a single app is not the end, but the start of your business.

   You need to market your application on different social media platforms and introduce your mobile application to your business website as well to attract relevant traffic.

   Apart from strategies, you may follow these methods to market your language learning application.

   • Write a blog or guest post
   • Create a landing page
   • Create video introduction and teaser
   • App store optimization
   • Offer promo, coupons, and discounts
   • App reviews

   We have even developed a video app for kids – Juvi, which comes with video monitoring services that show filtered content and a time tracker to monitor content consumption. Here is a testimonial of one of our clients.

   Michael Cameron wanted to build an education app that stands out from the competitors. The client was highly impressed by our team’s communication and app development skills. Check the complete client’s testimonial here.

But, you might have a question about why learners prefer the Duolingo mobile app? What is so unique about the app?

Let’s discuss the 5 unique language learning app features of the Duolingo app.

1. Offers Organized, Progressive Lessons

   Duolingo is effective in offering the best learning experience. The application offers a clearer route to complete the course step by step. As you progress with the new tutorials, new levels unlock, turning grey icons into colorized ones which shows that you have successfully completed the levels.

2. Regular Test Practice

   Duolingo allows you to strengthen your skills by offering you program tests, which help you to sharpen your vocabulary. You will get the chance to enhance your previously learned skills and repeatedly sharpen up your skills by revising what you have learned before.

3. Offers Byte Size Video Content

   Microlearning means dividing the content into smaller pieces. It may become harder for learners to absorb all the information in a single go. Therefore, providing bite-sized lessons is short and focused on a particular topic. Based on the information from SHIFT, microlearning increases student retention by 80%.

4. Allows You to Set Goals

   The human mind is wavering. We sometimes forget the things we start. Therefore, the app helps you remember the goals you need to achieve to get ahead with chapters. Duolingo app allows you to set goals between casual, regular, serious, and intense. As the complexity of the goal increases, so does its timing.

Type of Goals	Time
Casual	5 minutes
Regular	10 minutes
Serious	15 minutes
Intense	20 minutes

5. Scaffolded Support

   In the Duolingo app, you might have noticed that while going through the language learning courses, Duolingo provides relevant tips in between to engage learners and help them to understand the language better. That is known as scaffolded support.

   All of the integrated tips (tips that popups up in between your course) are useful to increase user retention. For example, suggestions like word translations, new word suggestions are extremely helpful and the scaffolded support feature does exactly that.
