# Eye Handbook vs VAS

The clearest difference is ads: VAS at none against Eye Handbook's shown. VAS also leads on rating (5.0 vs 4.8) and monetization model (free vs ad-supported). Eye Handbook's advantage is update cadence (every 2 weeks vs every 22 months) and ratings volume (1.2K vs 1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

VAS holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Eye Handbook has 1.2K ratings behind it against 1, so its average is the more settled of the two.

Eye Handbook ships an update every 2 weeks, VAS every 22 months. The most recent releases landed on September 16, 2026 and September 14, 2026 respectively.
