2つのカウントダウンタイマーとストップウォッチを持つ時計アプリです。自動車のラリー競技における時間管理に役立ちます。 カウントタウンタイマーは、スタート時刻と目標時間をセットすると到着時刻を計算し到着時刻までの残り時間をカウントダウンします。 ストップウォッチは、”START"ボタンをタップすると次の時刻の00秒に向けてカウントダウンを始め、時刻が00秒になると自動的に計測を開始します。ストップウォッチの計測を止めるには”FINISH”ボタンをタップするか表示されている計測タイムなどの数値部分をタップします。 このアプリを使用する場合iPhone側の”Watch”の設定で、"スリープ解除時間"と"時計に戻る"までの時間を長くしておくことを推奨します。 また、文字盤のコンプリケーションのひとつにこのアプリを割り当てておくと便利です。
