「メモ習慣」は、思いついたことをすぐ書き留めるためのシンプルなメモアプリです。アカウント登録もログインも不要で、開いたその場から書き始められます。 多機能なメモアプリを使ってみたものの、フォルダ分けやタグ付けが面倒になって続かなかった。そんな経験がある方のために、機能をあえて絞りました。画面にあるのはメモの一覧と入力欄だけ。「書く」「見返す」「消す」の3つしかないので、使い方を覚える必要がありません。 ■ ホーム画面ウィジェット 書いたメモをホーム画面のウィジェットに一覧表示します。アプリを開かなくても、いま何を書き留めてあるかがホーム画面でそのまま目に入ります。買い物リストや持ち物のメモなど、何度も見返したい内容と相性のよい使い方です。 ■ コントロールセンターからすぐ起動 コントロールセンターに「メモ習慣」のボタンを追加できます。ホーム画面でアイコンを探す手間なく、画面の端をスワイプしてワンタップでアプリを開けます。 ■ 振り返り通知 好きな時刻を指定して、メモを見返すための通知を1件セットできます。書きっぱなしで終わりがちなメモに、決めた時間に目を通すきっかけを作れます。 ■ 端末内に保存 メモは端末の中だけに保存します。アカウントを作る必要がなく、機内モードや電波の届かない場所でもそのまま使えます。 ■ ダークモード対応 端末の外観モードに合わせて、アプリもウィジェットも自動で切り替わります。 こんな方に向いています。 • メモアプリの機能が多すぎて持て余している方 • 起動してすぐ1行書ければ十分という方 • 書いたメモをホーム画面で常に見えるようにしておきたい方 • アカウント登録なしで使えるメモアプリを探している方 「メモ習慣」は無料でご利用いただけます。運営費用にあてるため、画面下部に広告を表示しています。 まずは1行、思いついたことを書き留めるところから始めてみてください。
