Ratings and reviews

It's a useless app which keeps stopping with a lot of ads being displayed over the app that cannot allow the learner to concentrate. Another disadvantage is that it can not be viewed offline. I don't recommend it for serious learning. Most data bandles are wasted in adverts instead of learning. Zero star as per my opinion You need to improve on it, it's still useless

This app is the new version of previous app where all content is same and it's awesome, I guess as previous app was having some software issue that's why you have launched this app , overall it is awesome

Not recommended for serious learner. It full time runs adds. Hindering the learning.
