Creating the App
Whether it is your own team of developers or a mobile app development company that you hire, they will have to follow few steps through the mobile app development process.
Come up with suitable content
Content is a very important factor when it comes to language learning apps. No matter how great the features and functionalities are, your app tends to lose its credibility among users without powerful content.
For language learning apps, you have to carefully pick the necessary grammar training programs, language sounds, video and audio content, etc.
Duolingo stands out among a large number of language learning apps in the market for its wide variety of content. Content covering almost all aspects of language learning is required to convince the users that your app can guarantee success in learning.
If you look into the history of the Duolingo app, the founders spent an incredible amount of time reading books based on language teaching, with them searching up about 3000 words in Google and translate it to English.
With the data gathered through their efforts, they launched the app’s web version that helped many professional linguists. Later, they added more new languages to the app as more people started showing interest towards it.
Decide on the app development platform
iOS and Android being the two popular platforms out there, it is natural for businesses to go for both. If you are capable of managing both platforms simultaneously and have enough budget, it is absolutely worth giving the users access to the application from different devices using both platforms.
However, if you are just a beginner in the language learning app business with fewer resources and budget, it is safe to launch the app over any one platform at the beginning, where a major portion of your potential audience is likely to be present.
Users always love apps with an appealing interface and intuitive navigation. Other factors that attract the users towards an app is the sense of familiarity and ease of use.
That is why it is necessary to do lots of brainstorming and go through several rounds of trial and error before finalizing the design. The key is to keep it clean, pleasant, and unique, with user-friendly navigation to gain the attention of users.
Also, use the apt and familiar icons, and decide on its placement in order to make the browsing experience a memorable one for the users.
Decide the technology stack
You can decide on your app’s technology stack by combining technologies that meet the requirements of the project and that go with the selected platform. Before making the final decision, it is wise to consult with the app development company you hire.
Include advanced technology
In recent years, going by the standards is considered boring. Users always seek something new and interesting, and that is why gamification of apps has been quite a trend these days.
In terms of language learning apps, you can include elements such as bonuses, achievements, and awards, that would retain the users’ interest and get them emotionally involved in the app for a long time.
Chatbots are one of the technologies that have become a norm for the majority of the apps in the market these days. This AI-powered technology can help guide the users to take further actions during the training in case they are lost.
The chatbots will also engage in conversations with the users to identify their preferred foreign language choice and help them to hold conversations in the language.
Other technologies that have to be included in language learning apps include AR/VR, voice recognition, Machine Learning, Cloud Natural Language Processing, and much more.
Including these technologies in the application will simplify the working of the app and, at the same time, makes it interactive and interesting for the users.
How Much Do You Have to Spend?
The cost to develop a language learning app can vary depending on the hired mobile app development company.
There are different factors to be considered, which include
- Development team structure
- Technology stack
- Tech expertise level
- Number of app features and their complexity
The app development cost also depends on the number of hours a development team spends on the project and in case the team includes specialists, their rates would be included as well. In terms of location and professional expertise, the estimated cost would range from $25 to $150 per hour of work.
