I used this app in my school days. I like it most due to its way to explain you the things in a new way ie, through 3D figures.
Support & Services -
Its support and service team is responsive and respond about your concerns in minimal time.
Information Depth -
Information depth was good as it covers contents which were not given properly or partially in ncert.
Content -
Content is good enough but only thing which I don't like is that they block you from learning if you can't solve questions too. And also even when you solve problems and unblock you after about 15 days and they unblock you only for 7 to 8 lectures.
User Interface -
Its UI is quite responsive and user friendly too.
Time to load -
Overall time to load was good. But its automatic mode was very bad as in fast internet too its video quality was very bad and in that kind of video quality you aren't able to see the things properly.
Overall app is very good for school going students of class 5 to 10 as its contents help them to learn the things more properly with the help of partical aspects which they use to explain in the lectures.
