# EyeToric vs IOL Reference

The clearest difference is rating: IOL Reference at 4.7 against EyeToric's 3.2. IOL Reference also leads on in-app purchases (none vs 2) and update cadence (weekly vs every 19 months). EyeToric's advantage is review sentiment (100% vs 89%) and iOS requirement (8.0 vs 15.5). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. EyeToric sells 2 one-off in-app purchases. IOL Reference asks for nothing beyond the download.

IOL Reference holds the better App Store score, 4.7 against 3.2. Both are backed by a comparable volume of ratings — 5 and 15 respectively. Written reviews complicate that: 100% of EyeToric's written reviews are positive against 89% of IOL Reference's, so the app with the better star average is not the one people write more warmly about.

EyeToric ships an update every 19 months, IOL Reference weekly. The most recent releases landed on September 30, 2026 and September 28, 2026 respectively.
