Ratings and reviews

As a developer and as a user of this application I can say that it is a great app that helps you alot to sharpen your skills and it comes with a good UX. I can conclude that I expect more technologies to be added and more questions will be added on the existing ones and overall questioning system should also include a workout like giving a problem and user provides solution by writing code thank you.

I cannot login into account "Unexpected error occured". And some problem with scroll sometimes I just can't scroll back because it scrolls infinitely. But quizzes are good, too bad optimization is bad

Very good app but having subscription for a month is not convincing me to purchase. One time fee for premium account is good option from consumer point of view atleast at starting stages of your application.
