多くの方からご要望を頂き、ついにiPhone版 フラッシュ暗算の登場です。 このアプリは、フラッシュ暗算考案者制作の日本フラッシュ暗算協会の公式ソフトです。 日本フラッシュ暗算協会は、日本国内で行われている全ての検定試験・競技大会・ギネスの公式ソフトを提供しています。 検定試験におきましては合格者が100万人を突破しました。 是非多くの方に、本物のフラッシュ暗算を体験していただきたいと思います。 機能 問題は、1桁2口3秒から3桁15口1.2秒までをレベル別に120段階で選択できるようにしました。 問題終了後、答えを入力すると正誤を音声で知らせます。 注意 最高レベル付近の問題では、機器の性能を超えたスピードになりますので、状況により表示にムラが出る場合があります。 今後、検定試験用・大会用・ゲーム用など、ご要望があれば制作をしたいと考えております。宜しくお願い致します。
