Learnchase is learning platform for students preparing for competition.
Learnchase has own website and his application in google.
But service provide by this app is very poor, you cannot rely on that.
Although all the contents for your respective competition is not available in learnchase website and the the available content has very less information depth.
The concept is not cleared by the admin and teacher of the website.
Also the website took to much time to load the content of the material.
Overall learnchase is not user friendly and we can say it make fool to all the middle class students.
So I will not recommend to go through this site, better to choose the other one.
