Verdict
The clearest difference is in-app purchases: Eye Handbook at none against COE Prep's 1. Eye Handbook also leads on ratings volume (1.2K vs 78). COE Prep's advantage is ads (none vs shown) and iOS requirement (10.0 vs 15.5). On price, rating, review sentiment and update cadence there is nothing between them.
