We live in a multilingual world, where increased globalization demands you to know a second language, which eventually gives you an advantage over others.
Learning another language is becoming a usual activity amongst the youngsters and business professionals. It’s because they want to lift the language barriers and integrate with the people globally.
Moreover, companies prefer bilingual professionals, as they seek to trade and create relationships with different countries. Learning another language is becoming easier with mobile apps. A language learning app uses AI and Machine Learning (ML) to enhance your skills.
This blog will describe everything you need to know about a language learning app and how to develop it.

How does Duolingo make money and What is Duolingo’s Business Model?
Duolingo initially employed a crowd-sourced business model, where organizations such as Buzzfeed and CNN paid them for translations.
Duolingo is a free app, but they have periodic advertisements on their platforms.
As they grew, they switched to a freemium model for their mobile app and web app known as “Duolingo Plus” and includes:
unlimited hearts,
level skipping,
progress quizzes, and
no advertisements

Why do you need a language learning app?
Learning a new language will enhance all aspects of your life. Learning a new language will make you a better person, will increase your career opportunities, and you’ll find out more about the world around you.
But are you willing to learn from an app?
Many people would prefer physical learning over learning virtually. Still, virtual learning has become a part of our lives due to the world’s current crisis, and many people believe virtual learning is the future of learning.
This is the part where a language learning app comes in, to be more precise, ‘a free app.’
You would want to learn many new skills, but there’s no time. Virtual learning saves most of your time and cost, giving you more time to learn numerous skills at once and saving your money so that you can invest at a more needed place.
Benefits of App Learning:
Inclusivity – Many students are shy or introverts, who might get excluded during a physical learning session, but this app helps them a lot.
Ease in Accessibility – Anyone can access the app and start learning by having an Internet connection and a Mobile phone. These apps can be accessed anytime over the internet, 24 hours a day.
Cost Saving – An app saves your travel cost, accommodation cost, and some other expenses. Moreover, the price you pay for virtual learning is very much lower than a physical classroom.
Expanded WorldView – Users can compete with people around the globe who are learning the same language. This competition makes it more interesting than a boring physical classroom.
Flexibility and Comfort – You can learn whenever you want at any hour of the day; learning from home is also comfortable for all of us. This is by far the best option for students with some physical disability.
Who are Duolingo’s Competitors?
There are many apps like Duolingo, but we have chosen the four best alternatives.
1. Babbel Language Learning
It is the world’s first language learning app, made in Germany, and debuted in 2007.
Babbel uses its user interface to adapt itself to the learning ability of the user. For example, if a user learns better through listening, the app will tailor itself to that preference and teach you accordingly.
Though the App only has 14 languages, most of them are European languages.
The App is free, but users can access most of their content only through their subscription model, which costs you $6.95 per month for 12 months.
2. LingoDeer
It is another language learning app famous amongst users. It is based in China and teaches you around ten different languages. This app provides the same experience as Duolingo, i.e., it gamifies learning.
LingoDeer provides comprehensive resources for students learning Japanese, Vietnamese, Mandarin, and Korean. The app is completely free, and unlike other free apps, it does not have any periodic advertisements, and students can also download lessons for free.
3. Busuu
This app is developed for those who want to learn in a group.
It is wholly focused on collaborative learning.
Students can get their performance reviewed by native speakers and learners for verbal and written exercises. It contains 12 Languages which are relatively minor. Most of the features of the app require a subscription.
The premium version of Busuu allows you to have a live conversation with native speakers and certifies you with McGraw-Hill Education.
4. Lingvist
A combination of machine learning, language statistics, and cognitive science theory.
It is based in Estonia. The app features only four languages for English speakers, French, German, Spanish, and Russian, and users can also learn Estonian.
It also teaches UK and US English to speakers of distinctive tongues. Lingvist uses AI and neural networks to enhance your learning ability. It keeps track of all your learning activities and presents you with daily goals.
Though the app features just four languages, it is deemed content-rich in every aspect, whether it’s vocabulary, grammar, or any other thing.
Like Duolingo, it also employs a freemium model, with subscriptions starting from $7.50 per month.
How to Build a Language Learning App?
Foreseeing Your App Envision your app so that you can distinguish your app from other apps by providing something that a user needs and does not exist in the world around you—e.g., deciding your course structure, UI, choosing your OS, etc.
Cost Analysis Your language learning app needs a hosting platform, developers, advertisements, amongst many other things. Determining your costs for all these services is a crucial step before the development of your app.
Developing your Application Hiring an excellent developer for your app. There are many developers in the market, but choosing the best of them is a task itself. After that, a prototype is developed so that the vision of your app is aligned with the vision of the developer. After the developer is finished with the development, the app is tested by collecting feedback from a group of people (beta testing). The development team does this testing too (alpha testing).
Launching the App Once your app has passed the tests, you are ready to launch the app in the market. However, you must seek approval from the OS companies before your app goes live.
Maintenance You must attend to user feedback, monitor your scaling needs, and update your apps occasionally to make them more interactive for users.
The demand for language learning and virtual learning is increasing day by day, and a language learning app can fulfill these demands. There are many applications available in the market, but the best of them is Duolingo.
Duolingo is an excellent application, but there are always some drawbacks, which an individual can see or feel.
We all have different perceptions, and more than 300 million people use Duolingo, which means hundreds of millions of perceptions.
The most common perception people carry is the voice used in the application. The voice is unclear because the pronunciation is very different from what we see or write, which needs more improvement.
Hence, many of us would like our variant of the app, with more distinctive features and more accessible experiences.
Are you one of these ‘many’?
If yes, then let’s get together and build an app that helps people overcome their language problems.
