What unique features can we add in our eLearning mobile application?

Question

Good morning, incoming 4th year, we've been working on an android mobile application called CLEA (C language eLearning application). A lot of apps like this are on the app store. We have been advised by the panelist that we should add some unique features that would greatly help or solve a problem since it is for our thesis. Please help, any suggestions or comments would be highly appreciated, thank you

Answer 1

One uncommon feature was offline feature, where people can still utilize the app (learn, read materials, practice etc.) in offline mode. That would be an added value ...

(Edit)
But by the guidelines, these types of content belong in users' feeds and not in forum ...

Answer 2

Kenneth Santos as Ipang mentioned this is more of survey type question / open-ended as well as offtopic from the q&a forum guidelines. Please feel free to utilize your post feed, I'm sure there are good suggestions waiting.
