高機能な電卓 vs Denpa Network Check

高機能な電卓は、日常の四則演算から高度な関数計算まで、1つの画面で扱える電卓アプリです。シンプルな「基本電卓」と多機能な「関数電卓」を用途に応じて切り替えられます。 入力中の式と計算結果をリアルタイムで確認でき、確定した計算はテープ形式で画面に残ります。確定後は、数字を押すと新しい計算を開始し、演算子を押すと直前の結果から続けて計算できます。 主な機能は次のとおりです。 - 四則演算、百分率、符号反転 - 三角関数、対数、累乗、平方根、階乗 - 順列・組合せ、度分秒変換、座標変換 - 10進・16進・8進・2進の切り替え - DEG・RAD・GRADの角度単位 - AUTO・FIX・SCI・ENGの表示形式 - Shift／Altによる追加機能 - Ansとメモリ機能 - セッション単位の計算履歴 履歴・設定・メモリ・作業中の式は端末内に保存されるため、アプリを終了しても続きから再開できます。ACは現在の計算を消して新しいセッションを始めますが、保存済みの履歴は削除しません。

Wi-Fi feels slow, but you cannot tell why. Denpa measures what is actually happening, so you can see which side the problem is on. Denpa measures response time, packet loss, download and upload speed, and DNS lookup, and splits your connection into two segments. ■ Two segments, measured separately ・Your device → the first device that responds (your router, or the carrier gateway on a cellular connection) ・The first device → the internet Video stalls. Pages do not open. Experience alone does not tell you whether the cause is inside your home or beyond it. Measuring the two segments separately narrows it down. ■ What it measures ・Response time ・Jitter ・Packet loss ・DNS lookup time ・Download and upload speed (upload requires a server that supports it) ■ It measures only when you tap Nothing is measured until you tap Start diagnostics. There is no background monitoring. ■ Findings come with what to do Issues are listed as Error, Warning, or Information, with why they were flagged and what you can try. ■ Measure how a web page loads Your line is fast, but one page still feels slow. Enter a URL and Denpa loads that page the way a browser does, then reports the load time, the amount transferred, and the speed over that period. The cache is emptied before every run, so measuring the same page twice does not change the conditions. The page stays on screen, and tapping a link in it measures that URL. ■ Save a location, watch it change Name a location and save the result. History shows a chart and a list for each location, and compares the averages. ■ What this app cannot do ・It cannot change your router settings. It narrows down the cause. ・It cannot measure other devices. Everything shown is seen from this iPhone. ・It cannot show signal strength (the bars). Only apps individually approved by Apple can read it. ・It does not make your connection faster. It is a tool for measuring and narrowing down. ■ Privacy ・Results, location names, and notes stay on your device. ・Nothing is sent to the developer or to a third party. There is no analytics, advertising, or tracking. ・Location is never recorded or sent. It is used only to show the name of the Wi-Fi network (SSID), because iOS requires location permission to read it. ・Measuring uses real network traffic. The speed test connects to Cloudflare by default, and you can change the server in Settings. The full list of destinations is in the privacy policy. ■ Requirements iOS 18.0 or later / iPhone, portrait only / Japanese and English Free. No in-app purchases, no ads, no account.
