You can transcribe safely and securely even in places where radio waves do not reach or in meetings with important content! A network is essential for general transcription apps because it is linked with cloud services, This application does not require a network because the processing is completed within the iPhone. Therefore, you can comfortably transcribe without any transcription failure or delay due to network connection failure. In addition, you can use it safely at work without being involved in information leakage on the cloud service side. (If you are worried, you can use it by blocking communication by switching to airplane mode etc.) Also, the function to save data is not added.

機械加工の切削条件、商売の利益計算、そして日常の関数計算。 仕事に必要なすべての計算を、これ一つのアプリで完結させます。 ただ計算するだけではありません。「現場で本当に使いやすい」を追求し、徹底的にロジックを作り込んだ、プロフェッショナルのための「万能計算機」です。 【主な機能とこだわり】 ■ 1. MC加工・切削計算モード(現場仕様) マシニングセンタやNC旋盤のオペレーター必須の機能を搭載。一方的な計算だけでなく、現場で頻発する「逆算・検算」に完全対応しました。 完全双方向リンク (n ⇔ Vc): 径(D)と速度(Vc)から回転数(n)を算出するのはもちろん、回転数を手動修正した際に「今の径でVcはいくつになるか?」を即座に逆算表示します。 送り速度の安全確認 (vf ⇔ fz): 送り(vf)を手動で下げた際、一刃送り(fz)がいくらになるかをリアルタイムで逆算。刃物の破損リスクを瞬時に判断できます。 ドリル・タップ完全対応: ドリルの基本である「2枚刃(Z=2)」をデフォルト設定に。タップ加工時はピッチ(P)優先で送りを自動固定します。 材質プリセット: アルミ、鉄(S45C)、SUS、樹脂、チタンの推奨切削速度をワンタップで呼び出し可能。 ■ 2. 商売・利益計算モード 「原価」「売価」「粗利率」のうち、わかっている2つを入力するだけで、残りの1つを瞬時に算出します。 利益額の表示: 利益率(%)だけでなく、「で、結局いくら儲かるの?」という実際の利益額(円)も同時に表示します。 直感シミュレーション: 「原価1,000円の商品を30%の利益で売りたい」「2,000円で売りたいが原価はいくらに抑えるべきか?」といった計算が一瞬で完了します。 ■ 3. 関数・RPN・カメラスキャン 関数電卓: sin, cos, √ などの基本関数を搭載。 RPNモード: 技術者に愛される「逆ポーランド記法」への切り替えが可能。 カメラスキャン: 手書きの数式や図面の数値をカメラで読み取り、そのまま計算機に入力できます。 ■ その他の特徴 計算履歴の表示(スクロール確認可能) 直感的な操作感とハプティックフィードバック 多機能かつ、快適な操作 いちいち電卓を叩き直すのが面倒、条件を変更したときの再計算を楽にしたい。 そんな現場の悩みを解決するために作られた、至高の計算ツールです。ぜひあなたのポケットに入れて、現場へ連れて行ってください。
