For a while, I have now noticed a real boost in every technology-based publication towards augmented reality and everything that has to do with AR.
Today, Mondly, a language learning application has just released its AR version.

I think this is something completely new, it feels different compared to games like pokemon go.
I think that application companies really started to progress with augmented reality, the level of interaction is improving.
You can try the application here: https://www.mondly.com/ar: it is only available for Android phones at this time and you only have 7 languages to learn.
