Bible App (Free) iOS, Android, BlackBerry, Windows Phone, Windows 8, Kindle Fire, Symbian, Java, HP/Palm. Developers, say this is the #1 Bible app in the world. That may be true given the hundreds of Bibles available for you to choose from in more than 1,000 languages. Some of the Bibles are approved Catholic versions like NAB-RE and Douay Rheims. Internet connection needed to use most content in this app, but some Bibles are imbedded in the app so you can read them off line. Unfortunately, none of the imbedded bibles in English are Catholic editions. Audio Bibles are available but not downloadable. These include Douay Rheims. Study tools include reading plans, search capability, note taking, highlighting and bookmarking capability.
Text can be sized for easier reading. Your bookmarks, highlights and notes are saved on YouVersion.com which you must log into to use. But this gives you cross-platform use wherever you go with whatever relevant device you use to access the Bible you are in the midst of reading.
You will enjoy the added bonus of videos in which portions of the Bible are dramatized in beautifully filmed enactments as the narrator reads from Scripture.
