A language learning app makes learning a new language much more accessible. It doesn’t matter which part of the world you live in; as long as you have a smartphone and a working internet connection, you can learn a new language. In a way, a language learning app democratizes language learning. 

Increase in demand 

As mentioned earlier, language learning apps are seeing year-on-year growth of 32%. This suggests the increasing demand for people trying to learn a new language. This will only increase in the near future as internet penetration increases and apps explore new markets.  

Wide reach 

The language learning app market is not limited to geographical location. The whole world with an internet connection is your market. You can expand operations in newer markets by adding new languages. This shows the vast potential of a language-learning app.   

Leverage cutting-edge technology 

A learning app provides cutting-edge technology to learners. They get a mixture of audio and visual exercises. These combine to give the best learning experience. The technology allows users to have a more personalized learning experience. This is excellent because not everyone will have the same knowledge of a language. Some are complete beginners, while others are intermediate looking to learn the nuances of a language.     

Things to Consider During Language Learning App Development 

Some things are non-negotiable when you are out to develop your language learning app. These will help your app not get lost in the sea of apps on the app store and increase your chances of competing with giants of the industry. 

Know your target audience 

You have to be aware of your target audience. What languages do they want to learn, and what stage of learning are they in? These are some of the questions which will help you design the features and user experience of the app. Knowing the target audience takes the guesswork out of your business, and you have a better chance of succeeding.  

Improving the learning experience 

A language learning app is essentially a learning app. If users don’t have a great time learning, they won’t be using it consistently. You can take a few steps to ensure this is not the case with your app;   

Gamification of learning 

Gamify the whole process of learning. This will make the process fun and enjoyable. Users are more likely to spend more time on your app when the entire process of learning is treated as a game. This is something significant players like Duolingo realize, and it is a major part of their experience.  

Motivate users 

People get busy with their lives, lose motivation and don’t find the time. As a business, motivating them to continue is in your interest. How can you achieve that? Give them rewards and points for maintaining a streak. Remind them about their progress through push notifications. Introducing competition by allowing users to compete with other users is also a great way to motivate learners.  

One-on-one learning options 

Give an option of one-on-one learning. This will be great for serious learners. You can even charge a premium for their service, which will become an additional source of income for the app. 

Audio options  

No one likes to pronounce a word wrong. Even your app users would love to know the correct pronunciation of a word. Give them exactly that by adding an auditory option. 

Community Building 

Humans are social animals. We thrive in communities. Form communities of your users by allowing them to invite their friends to your app. Another great way to form communities is to allow users of a specific geographic location to compete in a competition.

Push notifications

This will lead to more regular usage of the app, making more money for your business. 

One-on-one lessons 

Some serious learners would love to take one on one lessons to take their knowledge to the next level. One-on-one lessons also provide an extra stream of income for the business. They are a great addition to the whole experience of learning. 

User Interface 

The user interface will be a deciding factor in making the app fun and interactive. When done right, it can transform the whole process of learning.  This is why the user interface should be given ample attention to detail.
