EDMOND, Okla. — More than 500 years after Gutenberg, the Bible is having its i-moment.

For millions of readers around the world, a wildly successful free Bible app, YouVersion, is changing how, where and when they read the Bible.

Built by LifeChurch.tv, one of the nation’s largest and most technologically advanced evangelical churches, YouVersion is part of what the church calls its “digital missions.” They include a platform for online church services and prepackaged worship videos that the church distributes free. A digital tithing system and an interactive children’s Bible are in the works.

It’s all part of the church’s aspiration to be a kind of I.T. department for churches everywhere. YouVersion, with over 600 Bible translations in more than 400 languages, is by far the church’s biggest success. The app is nondenominational, including versions embraced by Catholics, Russian Orthodox and Messianic Jews. This month, the app reached 100 million downloads, placing it in the company of technology start-ups like Instagram and Dropbox.

“They have defined what it means to access God’s word on a mobile device,” said Geoff Dennis, an executive vice president of Crossway, one of many Bible publishers — from small presses to global Bible societies to News Corporation’s Thomas Nelson imprint — that have licensed their translations, free, to the church.
