Complete Guide On How to Make a Language Learning App like Duolingo

Duolingo's remarkable success can be attributed to a combination of factors that have reshaped the language learning industry. Not too long ago, Rosetta Stone had a virtual monopoly, raking in over $200 million annually from its students. However, they seemed to overlook the growing demand for free language learning content, which left a gaping void in the market. This opened the door for Duolingo, a language learning app that was not only free but also incredibly effective.

In no time, Duolingo gathered a staggering 25 million active users and evolved into a multi-million dollar venture. The most astounding part is that they achieved this without asking their users for a dime. Duolingo's success can be primarily attributed to two key factors: identifying and tapping into massive language learning markets, and an astute understanding of the industry that led them to a free and accessible niche.

Other notable players in the language learning arena, like Preply and Babbel, also made substantial headway by leveraging user feedback and delivering high-quality educational content.

How Do Language Apps Like Duolingo Work?

Those who haven't had the opportunity to use language learning apps yet might find it difficult to imagine how these apps work. Here are the must have features that e-learning apps incorporate to make studying more successful.

Training Exercises

Language learning apps often include various exercises that focus on the language the user is learning, increasing complexity during the learning process. Some of these exercises include:

• Matching the word in the foreign language with the correct word in the native language.
• Reading a short passage and answering a comprehension question.
• Listening to a passage and answering questions or completing sentences with missing words.

Video Content

Unlike reading texts or listening to passages, videos include strong visual cues that allow the users to understand what's happening even when the language becomes difficult to follow. This gives video content the ability to motivate students as they will be able to understand a real person speaking a foreign language more easily.

After all, understanding someone speaking in a different language is a huge milestone.

Books and Library Access

This type of content provides essential theoretical knowledge, such as grammar or semantics, that helps improve language learning beyond a set of words and phrases. Learning a vocabulary is fairly easy, but it’s impossible to combine the words into a sentence without knowing the linguistic rules.

Chatbots

Chatbots are an excellent addition to language learning apps as they create a compassionate presence and can encourage users to continue learning. Duolingo, for example, features advanced AI algorithms that can understand the users and respond contextually and uniquely. This means that different users will receive different replies for the same inquiry, based on their personal preferences.

How Do Language Learning Apps Make Money?

Let's explore some of the most common ways language learning apps make money.

#1. Offer a Free Trial Period

Many apps provide a free trial period, but there's a catch. Users have to input their payment details before they can access the full array of features. These trials are usually time-limited but often include premium features. 

A prime example here is Duolingo. They've taken a freemium approach, granting users free access to basic features while tempting them with paid subscriptions for extra perks. In fact, an interesting fact about Duolingo is that a substantial 74% of their revenue in 2022 came from these subscription fees.

#2. Subscription Model

Take Babbel, for instance. They offer traditional digital language courses featuring dialogues and grammar exercises. While they do provide a free trial period, their primary revenue stream comes from selling various language learning courses and managing in-app advertising.

#3. Leverage Referral Programs

One way to get the word out and acquire new users is through a referral program. Current users are encouraged to recommend the app to their friends, expanding the user base.

#4. Incorporate Advertising

Another monetization strategy is to incorporate advertising within the app. This can include banner ads, sponsored posts, and other forms. App developers get paid every time a user clicks on one of these ads.

#5. In-App Purchases

In-app purchases are a versatile monetization model. Apps can sell additional features, premium subscriptions, or upgrades without requiring users to leave the app. For instance, in Memrise, users can purchase training points, unlock extra features, or even spend real money on in-game characters.

These monetization strategies offer flexibility and can be combined to create a sustainable revenue stream for your language learning app.

What Main Features Do You Need to Build an App for Learning Languages Like Duolingo?

If you’re considering developing a language learning app, there are some essential features that a basic platform requires to be successful. Here’s an overview of such features in Duolingo.

User-Friendly Design

It's crucial to keep a uniform look and feel in your app, which means using the same colors, fonts, and button styles throughout. This kind of consistency creates a sense of familiarity, making it simpler for users to move around the app.

Usability should be a top priority. You want users to effortlessly interact with your application. That means making sure buttons and menus are easy to tap or click – in other words, optimizing touch targets. Plus, the text should be large enough to be comfortably read on various screen sizes. When you nail these design and usability aspects, you're giving your users a smooth language learning experience.

It's also essential to incorporate straightforward and intuitive navigation within creating a language learning application. This ensures that users can effortlessly reach various sections of the application. To achieve this, establish a clear hierarchy and organize your content logically. This approach helps users find what they're looking for without the frustration of getting lost in a maze of options. In the end, it's all about making the user's journey through your app as smooth and user-friendly as possible.

Learn As You Play

As already mentioned, many language learning apps feature gamification techniques that make learning fun. For example, Duolingo, in particular, rewards users with points when they complete a lesson successfully. On the other hand, if they get something wrong, they lose a life.

All lessons use interesting visuals that make an app look more like a video game instead of a plain, boring learning tool. Because the app looks fun and the lessons are interesting, users learn with Duolingo on a daily basis for extended periods of time.

Networking

In addition to learning, language apps can be a means of socialization. Almost all language learning apps feature something that allows them to communicate with other users in a foreign language.

Duolingo has a 'club' that resembles a Facebook page with scheduled chats. LingQ, on the other hand, features a 'forum' where users can communicate with people from the same country or people who learn the same language.

Achievements

Language learning apps incorporate achievements that motivate the users to continue their learning. For every lesson they complete, users receive points that help them progress to more advanced levels. Some apps include coins and gems that allow users to buy in-app items. Some apps present units as game levels, and the app awards them every time they complete a level.

Account “Health”

The creators of Duolingo believed that including only positive reinforcement in the app wouldn't encourage users to work harder. So, Duolingo "punishes" its users for making a mistake by weakening the user's virtual health. If the health drops to zero, the user cannot continue with learning unless they correct the mistakes. However, the creators didn't want to discourage their users, so they made sure that their health was restored over time.

This approach allows the app to point out to users that they are making a mistake but in a fun and playful game format that won't discourage them.

Microlearning

Microlearning is like bite-sized information on a digital platter, where educational content is broken down into small, easily digestible segments. It's a bit like the idea of having smaller, more frequent meals for quicker absorption. Each of these segments typically spans just 5 to 8 minutes, during which the goal is to convey a concise thought, idea, or nugget of knowledge.

These microlearning modules, also known as microcourses, offer a fantastic way to provide precise, practical solutions to specific questions or problems. Essentially, any kind of online learning materials – whether it's how-to videos, podcasts, presentations, scripts, or assignments – can be delivered in this compact and effective microlearning format.

Community

This feature serves as a platform for users to connect and engage with fellow language learners, encouraging peer-to-peer support and motivation. It facilitates language exchange partnerships, enabling users to practice with native speakers of the language they're learning, enhancing real-world language skills. Users also can access forums and discussion boards for asking questions, sharing insights, and discussing language-related topics.

Push Notifications

Push notifications are brief messages designed to update users about specific events or actions taking place within the application. When a user interacts with a push notification, it directs them to a designated screen within the app.

These notifications play a pivotal role in retaining users, with the potential to boost retention rates by a substantial 3 to 10 times. Additionally, when these notifications are personalized and connected to specific triggers, they can drive a remarkable 48% of users to make in-app purchases. So, they're a powerful tool for enhancing user engagement and conversion.

Offline Mode

In today's app landscape, ensuring that mobile apps function seamlessly in offline access has become a crucial component. It's an integral part of delivering the finest user experience. The ability to work flawlessly without an internet connection not only broadens the user base but also enhances the application's reputation and boosts overall user satisfaction.

How to Build Language Learning Apps Like Duolingo

Now that you know what language apps are and which features they usually have, it's time to discover the app development process. Note that coding the platform is just a part of the big picture that usually happens in stages.

Stage 1. Before You Make a Language Learning App

Between forming an idea and bringing it to life, the key step of any project is researching the market and identifying what problems your idea will solve for the target audience.

Market research

The online language learning market almost hit the $12.5 billion mark back in 2019, and it’s expected to grow twice the size by 2027. According to InMobi research, that comes from the ever-growing pool of 1.6 billion global users.

Aside from the big numbers, you should also consider that there are two types of users in this market – individual users and institutions. Most mobile language learning apps cater to the former. However, it’s also possible to integrate teacher tools and develop a language learning app.

Your market research could take a turn in a completely different direction based on what user you focus on.

Target audience

The type of user you choose will also dictate what problems your app should solve. For example, an app for institutions can provide a teacher’s administrative panel for customizing additional learning exercises based on the language course progress. There could also be a community section where the teacher could answer students’ questions.

On the other hand, a discussion section for students solves the question of how to negotiate the meaning of words and facilitates practicing language skills with peers. A language app solves the issue of boredom –studies show that students enjoy using devices to learn new words, but language apps also provide variety and tackle different language skills.

You can identify target audience problems through target population surveys and competitor analysis.

Once you have all this data (target audience and competitor analysis), you can proceed to design your app.

Stage 2. Design

A good design will attract new users and ensure a smooth user experience.

The design process can be split into micro-stages:

• Creating a visually appealing logo and coming up with a catchy name.

• UI research and UX Map that would define the design theme, color palette, and other important app interface details.

• Developing app screens. This last step is the most demanding one and requires maximum attention.

Stage 3. Programming

This stage might be the most demanding and can take up to 1,000 hours of work in total. It includes several phases, starting with choosing the programming language, technology stack, platform (iOS/Android/Hybrid) and development itself.

Ideally, the app should be compatible with a variety of devices. In addition, many app creators opt for web development as well in order to make their app available from a browser.

After the development process is over, every app should undergo QA (quality assurance) to eliminate any bugs. The app must work flawlessly once it is released so that users who download it can leave positive reviews and help the app become visible in Google Play or Apple App Store.

Once the app is fully optimized, it is ready to be published. However, there’s one more stage before that.

Stage 4. Marketing and Sales

When a new app is developed, it is important to get the word out and interest as many users as possible to download it. Using social media ads is an excellent way to spread the word and target potential users.

You can capture and share captivating screenshots or videos that show the app's greatest strengths and point out why it is different from the competition. Ideally, you should combine this stage with the later programming phases, so you already have an audience once the app is up and running.

Stage 5. Publishing on App Stores

Publishing an app on Google Play and Apple App Store is a straightforward process. However, before the app is published, it undergoes a review stage.

Apple App Store has strict guidelines and many new apps are rejected. However, as long as your language app doesn't have any major bugs, is compatible with a variety of iOS devices, respects the privacy and user data guidelines, and has decent UI, it will be accepted.

Google Play, on the other hand, is a bit less strict. Still, there are quite a few steps developers need to undertake before their app is published:

• Sign up for a developer account.
• Test the app against the quality guidelines.
• Run internal tests on up to 100 internal testers to get feedback before making the app available.
• Publish and promote it.

Budgeting and Language Learning App Development Costs

Unless you have excellent UI/UX design skills and you're a professional developer, it can be a challenge to create a language learning app on your own. And even then it’s a time-consuming process.

While a costly process, it’s more efficient to hire an entire development team to produce it. So, let’s talk about the cost to develop a language learning app.

Design Costs

The design stage takes around 200 hours, including the creation of the logo, UI research, and the formation of a UX map.

Depending on who you're working with and how complex you want your app to be, this stage can set you back a couple of thousand dollars. For example, you can achieve a design like Duolingo for about $5,000.

Development Costs

Mobile app development is very pricey, as it takes approximately 1,000 hours to develop an app to learn different languages, costing up to $35,000.

This number is calculated based on the average rate of IT specialists in Eastern Europe ($35–$55 per hour). The costs vary based on the country of the company you choose to work with.

For example, American and West European developers can charge up to $150 per hour.

Publishing Costs

Believe it or not, Google Play and Apple App Store aren’t free to use:

• Apple App Store charges $99 per year.
• Google Play charges a one-time $25 developer fee to publish apps.

Conclusion

Developing a language learning app is an excellent idea at this moment, as the demand for such apps is high. They are a brilliant exercise for your brain that helps enrich your vocabulary. The variety of tasks help develop different learning skills like pronunciation and translation, and they simply get you out of boredom.

However, in order to create an app, you will have to set aside a significant amount of money and time. If you want a successful and efficient tool, a good solution for this is working with experts who can tackle every stage of custom app development.

The Geniusee team is made up of technology-addicted specialists who create custom web platforms and mobile applications with different levels of complexity, step-by-step, from requirements elicitation and design to technical support in the future.
