クソアプリアドベントカレンダー11回目の開催です。とうとう干支一周にリーチがかかりました。今年も役に立たない、世の中に貢献しないアプリとかサービスを出しあって遊ぼうぜ！
年末のお祭りに乗っかってラフに開発を楽しみましょう！

【11/22 ハッカソンやります＠東京】
おそらくハッカソン開催は今年で最後です。奮ってご参加ください。
https://kuso-app.connpass.com/event/371424/

下記レギュレーションをよくお読みの上ご参加ください。

クソアプリアドベントカレンダー2025のために新規で何らかの作品や機能を作成してください。
既存のサービスやアプリを持ち出す場合は、クソアプリアドベントカレンダー2025のためのバージョンアップなど新規の開発部分があることを条件とします。既存作品の紹介だけという形の記事はご遠慮ください。
アドベントカレンダーに出す対象は自作の作品であることが条件です。
どんな内容のものでも構いません。それこそ下ネタでも大いに結構ですが、個人や特定の組織などを誹謗・中傷や名誉を害するようなものは投稿しないでください。
カレンダーの記事を投稿するプラットフォームはどこでも構いませんが、当該プラットフォームの利用規約に沿った形となるようにしてください。
参加席だけ押さえておこう、という動きについてはカレンダー2以降でお願いします
