The call

The clearest difference is in-app purchases: Optical Simulator at none against EyeScaler's 1. Optical Simulator also leads on iOS requirement (11.0 vs 15.0). EyeScaler's advantage is update cadence (fortnightly vs every 4 months). On price, ads and device support there is nothing between them.
