Parallel Books is a free app designed for people learning, perfecting or practicing a second language. It displays two translations of the same book beside each other and keeps the two translations in sync as you read.
Read a book in your new language while having a parallel copy in your mother tongue handy for reference. Now thanks to Parallel Books, this technique is available on iPad, iPhone and iPod touch. Translations will automatically stay in sync, leaving you free to be immersed in the words on the page. Reading a book in two different languages at the same time has never been easier!
