# Spring Sight vs 视力筛查

The clearest difference is in-app purchases: 视力筛查 at none against Spring Sight's 1. 视力筛查 also leads on iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. Spring Sight sells 1 one-off in-app purchase. 视力筛查 asks for nothing beyond the download.
