Sword of the Spirit v2.0 has been released for iOS. It was developed by Squirble. It is an educational game which helps people learn the most quoted verses in the Bible.
Sword of the Spirit supports the King James version (KJV), New International version (NIV), and New International Reader’s version (NIRV). We upgraded the app to v2.0. v2.0 adds support for many languages and adds responsive UI so it can work correctly and look better on devices from iPhone 3 up to iPhone 8.
Update: as of 2016, Sword of the Spirit had been downloaded over 100,000 times!
(Note: this app is no longer available from Apple since there is no 64-bit version.)
