# Eye Handbook vs mEyeSim

The clearest difference is in-app purchases: Eye Handbook at none against mEyeSim's 3. Eye Handbook also leads on ratings volume (1.2K vs 2) and update cadence (every 3 weeks vs every 2 months). mEyeSim's advantage is ads (none vs shown). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. mEyeSim sells 3 in-app purchases, starting at $19.99 per 3 months. Eye Handbook asks for nothing beyond the download.

mEyeSim 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 2, so its average is the more settled of the two.

Eye Handbook ships an update every 3 weeks, mEyeSim every 2 months. The most recent releases landed on October 29, 2026 and October 9, 2026 respectively.
