# Multifocal Lens Analyzer vs EWA

The clearest difference is rating: EWA at 4.7 against Multifocal Lens Analyzer's 3.0. EWA also leads on update cadence (weekly vs every 2 months) and ratings volume (196K vs 1). Multifocal Lens Analyzer's advantage is ads (none vs shown) and iOS requirement (13 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Multifocal Lens Analyzer sells 1 in-app purchase, starting at $45.99 per year and EWA sells 8 in-app purchases, starting at $11.99 per month. Whichever you choose, the download price is not the number that matters.

EWA holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: EWA has 196K ratings behind it against 1, so its average is the more settled of the two.

Multifocal Lens Analyzer ships an update every 2 months, EWA weekly. The most recent releases landed on October 9, 2026 and October 17, 2026 respectively.
