APSカップ各競技の練習用タイマーと記録を残せるようにしたアプリです。 現在はハンドガンクラスの競技であるブルズアイ、プレート、シルエットに対応しています。 (注:ライフルクラスには現在対応していません) <タイマー機能> 練習用タイマーは音声で開始の合図をするので、わかりやすいです。 また、音声ではなくブザーでの合図も可能です。 例えばプレート競技の合図は、 1.プレート スタンバイ レディ 2.開始のブザー 3.3秒後に終了のブザー といった流れを繰り返します。 開始時間の設定や各プレートの間隔の変更もできます。 (実際の競技会場とは少し合図の間などが違います) <タイマー機能:プレート競技の邪魔機能> プレート競技中に発生することがある中断やタイミングずれなどを再現した機能です。 「プレートスタンバイ レディ」後に中断し再開する機能などです。 <レギュレーション> APSカップのレギュレーションを確認できます。 あくまで簡易確認用の抜粋です。 「日本エアースポーツガン協会」公式のレギュレーションを確認してください。 <記録機能> 各競技の記録画面では画面をタップするだけで得点計算ができます。 各競技単体、3競技での計算をしたいなどそれぞれに対応しています。 <手動音声再生機能> 手動で各競技の音声、プレート競技の3秒ブザーなどを鳴らすことができる機能です。 複数人で練習する際に使用すると便利だと思います。 <注意事項> ・本アプリ利用の結果生じた、いかなる損害または第三者からのいかなる請求についても、 作者は一切その責任を負うことはできません ・エアーガンなどでスマホ等を壊さないように注意してください ・ライフルクラスには現在対応していません ・本アプリは日本エアースポーツガン協会とは何の関係もありません ・タイマーの時間は可能な限り正しくなるようにしていますが、厳密には、ずれている可能性があります
