# CFR AI vs OSHA Reference

The clearest difference is monetization model: OSHA Reference at free against CFR AI's subscription. OSHA Reference also leads on update cadence (every 2 days vs every 2 months) and iOS requirement (18.0 vs 26.0). CFR AI's advantage is device support (3 vs 1). On price, rating, ratings volume and ads there is nothing between them.

On the App Store both sit at effectively the same score — 5.0 for CFR AI against 5.0 for OSHA Reference. Both are backed by a comparable volume of ratings — 1 and 1 respectively.

CFR AI ships an update every 2 months, OSHA Reference every 2 days. The most recent releases landed on September 12, 2026 and September 9, 2026 respectively.
