BookBox is an iPhone application developed by BOOKBOX INDIA PRIVATE LIMITED. It falls under the Education & Reference category and is available for free. This app brings users animated stories in English, French, Spanish, and Hindi, with more languages and stories on the way.

The standout feature of BookBox is its use of Same Language Subtitling (SLS), a scientifically proven method to enhance reading, vocabulary, and listening comprehension skills.
