Gitabase is a free app created by Ivan Sharov for the iPhone that provides an extensive collection of Vedic literature, including the Bhagavad Gita As It Is, Srimad Bhagavatam, Sri Caitanya Caritamrita, and more. The app allows you to read these texts offline, making it convenient for those who want to access them on-the-go.

One of the standout features of Gitabase is that it provides the original Sanskrit texts along with the translations, which gives readers a deeper understanding of the material. The app also allows users to bookmark their reading progress, add notes, and highlight important quotes from the texts.

While the app is free to download, the search function is a paid feature that can be purchased via in-app purchase. Users can opt to purchase it for an unlimited time or for one year or one month as a subscription. The app's terms of use and privacy policy can be found on the Gitabase website. Overall, Gitabase is an excellent resource for those interested in Vedic literature and philosophy.
