What are the most useful features of language learning apps?

Hello everyone,

As language learners, we are fortunate to have access to a wide range of language learning apps that can help us practice and improve our skills. However, with so many apps available, it can be difficult to know which ones are the most useful.

So, I wanted to start a thread to get your opinions on what you think the most useful features of language learning apps are. Here are a few questions to get us started:

What features do you look for in a language learning app?
What features do you find most helpful in terms of improving your language skills?
Are there any apps that you think do a particularly good job of incorporating these features?
I’m excited to hear your thoughts!
