Verdict
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.
