This app is really good for students to clear their concepts. But I think for competitive exams like JEE advance or aiims it needs to improve.
And specially for those students who are currently studying in Hindi medium schools and want to prepare for exams this application is useless for them.
I think there should be a separate section for Hindi medium students in this app.
And it needs better supplementary for competitive exam, like which the leading coaching institutes of India use for their students.
