### 5/5 — 同期が失敗しません

*2023-06-14*

家族と買い物リストを共有するために使っています。アップル公式のリマインダーが同期がうまく行かないことが多く、こちらを使うようになりました。もう二年ほど使っていますが、一度も同期の問題か生じたことがなく、とても助かっています。
ただ、AppStoreでTODO!と検索しても見つかりません。こういう小さくてもしっかり動くアプリを見つけやすくしてほしいです。

自分は満足してはいるのですが、以下は家族からのリクエストです。チェックをつけた項目が、いつチェックしたものかわかるとうれしいです。それが数日経つと消えたりしたら最高です。
