I used Google Translate to translate the 9 chapters with the assistance of the Translation Editor in Android Studio. It took me about 2 months to translate the content to Hindi. There is a switch in the app settings to enable Hindi.
I also included dark mode into the app which can also be accessed in the app settings. Am currently planning on adding features that will keep users around for the foreseeable future. Am currently at approximately 300,000 users since the launch of this app in Feb 2018
