Crimson Bible: Offline Study
KJV, Strong's & concordance
Free · Designed for iPad. Not verified for macOS.
Crimson Bible is a fast, beautiful Bible app that works entirely offline: no account, no ads, no tracking. Ever.
Search the way you actually think. Ask "verses about anxiety" or "what does the Bible say about forgiveness" and get the right passages — powered by on-device AI search that understands meaning, not just keywords. Type "Juan 3:16" or "創世記 1:1" and jump straight there.
