iOS Engineer

We want to be the first thing one billion people think of when they think of books.

We've started with a high-craftsmanship native iOS app to track and discover books, targeting the 20 million Americans who read a book a week and the hundreds of millions who aspire to read more.

Since launching on Christmas Eve, we've had 100,000 users track 13 million books and log 250,000 hours of reading time.
