「あと何分?」って、意外とパッと出てこない。 だから、アプリで解決しました。 タイムプラスは、決めた時間からの残り時間を大きく表示する、シンプルなカウントダウンアプリです。複数のカウントダウンを同時に並べて、終了時や「◯分前」にアラームでお知らせします。 ■ 使い方はかんたん ・「+」ボタンでカウントダウンを追加 ・ホイールを指で回して「◯時間◯分◯秒」を選ぶだけ(最長99時間) ・残り時間が毎秒減っていき、0になったら「終了」表示 ・ホイールを回し直せば、その時点からやり直し ■ ここが便利 ・カウントダウンは同時に複数並べられます(最大30個) ・アラームは「終了時」のほか「1分前〜10時間前」も選べます ・1つのカウントダウンにアラームを複数設定できます(終了時+5分前 など) ・開始方法は3通り(今の時刻で固定/開始時刻を指定/時間連動) ・日数計算タブつき(日付から日付までの日数・◯日後・◯日前の日付をすぐ計算) ・アプリを閉じてもカウントダウンは進み、時間が来ればアラーム通知が届きます ・設定した内容は次回起動時もそのまま ■ こんなときに ・「会議まであと30分。5分前に教えて」 ・「カップ麺の3分」「休憩の15分」 ・「あと2時間の作業。残り時間を見ながら集中」 ・「薬を飲むまであと6時間。忘れないようにアラーム」 余計な機能はありません。残り時間とアラームだけを、いちばん速く。
