# No vs Red Days

The clearest difference is in-app purchases: Red Days at none against No's 1. No's advantage is iOS requirement (18.4 vs 26.2). On price, ads and device support there is nothing between them.

Both are free to download. No sells 1 one-off in-app purchase. Red Days asks for nothing beyond the download.
