# Check Site vs C%

The clearest difference is in-app purchases: Check Site at none against C%'s 1. Check Site also leads on iOS requirement (13.0 vs 17.0). C%'s advantage is update cadence (every 3 weeks vs every 3 months). On price, ads and device support there is nothing between them.

Both are free to download. C% sells 1 one-off in-app purchase. Check Site asks for nothing beyond the download.

Check Site ships an update every 3 months, C% every 3 weeks. The most recent releases landed on November 9, 2026 and October 31, 2026 respectively.
