# シークレットカレンダー vs ふたりの暦

The clearest difference is in-app purchases: シークレットカレンダー at none against ふたりの暦's 1. シークレットカレンダー also leads on iOS requirement (11.0 vs 17.0). ふたりの暦's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. ふたりの暦 sells 1 one-off in-app purchase. シークレットカレンダー asks for nothing beyond the download.
