Hey, I have a suggestion for you that if you are using Android Phone then I would recommend you about an application named "Shrimad Bhagavad Gita and Gita Saar in English".
Shrimad Bhagavad Gita in English consists of 18 chapters and Gita Saar also. The application works offline. You can also bookmark the chapter that you liked. And many more interesting features are there.
Hope, You enjoyed it!
