Hi

You can definitely download study. com app for free in iOS and Android . You will find the app Study. com official in Google play store as well as Apple store. The app is  39.63MB. You can create a free account the instructions are available once you open the app but you will not have access to all the study materials. If you want to get access to all the resources then you have to get a subscription which costs around INR 3000/month for a premium subscription.

Hope the information is helpful to you
