Verdict

The call

The clearest difference is in-app purchases: Eye Handbook at none against WikEM's 10. Eye Handbook also leads on review sentiment (82% vs 54%). WikEM's advantage is ads (none vs shown) and update cadence (every 5 days vs every 3 weeks). On price, rating, device support and iOS requirement there is nothing between them.
