わが家メモ
Read full descriptionHide full description
「牛乳、切れてた」——そう思った瞬間に書けなければ、メモは意味がありません。 わが家メモは、「買うもの」と「やること」の2つを、家族で共有するアプリです。 どちらも、思いついた瞬間に書けます。 ■ 開いた瞬間に書ける アプリを開くと、そこはもう入力欄です。階層をたどる必要はありません。 続けて何個でも打てて、キーボードは開いたままです。 分類も、優先度もありません。入力の手間を増やすと、メモは続かないからです。 ■ 買うもの — 店で思い出させてくれる 「駅に着いたら」を登録しておくと、そこに着いたときに知らせます。 家に着いてからでは遅いので、まだ寄り道できる場所で鳴ります。 「今日中」の印を付けたものがあるときだけ鳴るので、鳴りっぱなしにはなりません。 帰る前の時刻を決めて、買うものの件数を知らせることもできます。 ■ 買うもの — 切れる前に、先回り 同じものを3回買うと、買う間隔をおぼえます。 そして次に切れそうな頃、リストの上にそっと出します。 「前回から7日 / いつもは約7日」——なぜ出ているかも一緒に出ます。 登録作業はいりません。買っていれば勝手におぼえます。 ■ やること — 期限をつけて ゴミ出し、電球の交換、保険の更新。買い物以外の用事はこちらへ。 期限は「今日・明日・明後日・1週間後」からひと押しで選べます。 期限が近づくと、タブに件数が出ます。 ■ 買ったもの・終えたことは、記録に残る 片付けると、それぞれ履歴に残ります。あなたは何もしなくて構いません。 まちがえて片付けても、履歴から元に戻せます。 ■ 家族で同じリストを 招待コードを送るだけで、同じリストを一緒に使えます。 誰が買ったか、誰の担当かも分かります。 通知の場所と時刻は、それぞれの端末で別々です。 相手が登録した駅であなたの iPhone が鳴ることはありません。 ■ ログインしなくても、全部使えます ログインが要るのは、ほかの人と同じリストを使うときだけです。 それまでは、書いたものはこの端末の中だけにあります。
