Verdict

The call

The clearest difference is review sentiment: Eye Handbook at 81% against Face2Gene's 17%. Eye Handbook also leads on rating (4.8 vs 2.1) and update cadence (every 3 weeks vs every 3 months). Face2Gene's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement there is nothing between them.
