Data Pocket is a versatile note-taking app that lets you easily customize text with adjustable font sizes, colors, and other formatting options using simple one-tap controls. It also supports creating photo journals by inserting images into your notes. Your notes can be: - Organized by attaching them to a calendar. - Sorted and stored in a hierarchical folder structure. The app also includes a shared calendar feature that allows multiple users to edit the same calendar collaboratively. In addition to text notes, you can manage photos, videos, music data, and web pages in the same folder hierarchy, each with its own comments. You can automatically play videos or music stored in a folder, with customizable playback order and repeat settings, and even transfer music files to your Apple Watch for standalone playback without your iPhone. The app also allows you to extract audio from videos, such as screen recordings, and compress and save it as music data. Data Pocket also provides powerful features such as full-text search across all notes, text editing utilities, and automatic text recognition (OCR) from images. Furthermore, text notes can be displayed with automatic scrolling or viewed directly on your Apple Watch. Additional features include RSS news feed integration and options to customize button layouts and the startup screen appearance, among many other useful tools. Starting from version 2.0, WebLink feature has been added, allowing users to view and create notes in this app from a web browser on a PC or other devices.

ふつうの電卓は、「=」を押した瞬間に、それまでの計算の過程が消えてしまいます。手元に残るのは最後の数字だけ。「さっき何を足したんだっけ」と思ったときには、もうたどれません。 あしあと電卓は、計算の過程を「足あと」として画面に積み上げます。ノートに数式を書き連ねていくように、計算が縦に伸びていく電卓です。 ■ 結果を引き継いで、次の行へ 数式を入力して「=」を押すと、その行で結果が確定します。そのまま演算子や関数キーを押すと画面は自動で改行され、直前の答えにつながった新しい式が始まります。紙にメモする、クリアしてから前の数字を打ち直す、といった手間はありません。思考の流れのままタップしていくだけで、多段階の計算がそのまま画面に残ります。 ■ 過去の行をタップして、その場で直せる 打ち間違えても、最初からやり直す必要はありません。積み上がった行をタップすると、その式をその場で書き換えられます。数字を1つ直せば、その行だけでなく、前の答えにつながった先の行もまとめて計算し直されます。どの段階で間違えたのかもひと目で分かります。 ■ 一区切りついた計算は、自動で履歴に ACで区切るまでの一連の計算は、自動的に履歴として端末に保存されます。保存ボタンを押す必要はありません。「先週のあの計算」を履歴から開けば、そのまま続きを計算できます。 ■ 足あとごと、そのまま渡せる 画面に残った足あとは、テキストとして他のアプリへ共有できます。結果だけでなく、そこへたどり着いた過程ごと相手に渡せます。 ■ こんなときに ・買い物や家計 — 複数の商品の合計を出し、そのまま「÷12」で月あたり、「÷30」で1日あたりへ。総額・月・日がすべて1画面に並ぶので、全体を見失いません。 ・仕事の試算 — 単価と数量、税、割引を段ごとに積み上げ、どの数字を変えると結果がどう動くかをその場で試せます。 ・学習 — 途中式が残るので、答え合わせのときに、どの段階で間違えたのかを自分で見つけられます。 ■ 表示と操作 大きな数は3桁ごとに自動でカンマが入り、桁の大きな値や小さな値は指数表記で表示します。長い式は行の中で縮めて収めるので、折り返しで見失いません。縦画面では関数キーを引き出して使え、横画面とiPadではすべてのキーを一覧できます。VoiceOverに対応し、各行の式と結果を読み上げます。 ■ できること 四則演算、括弧、べき乗、平方根、累乗根、パーセント、階乗、逆数、絶対値、三角関数・逆三角関数、常用対数・自然対数、指数入力、円周率(π)、自然対数の底(e)、乱数、税込・税抜計算。角度はDEG(度)とRAD(ラジアン)を切り替えられます。 計算履歴は端末の中だけに保存され、外部へ送信されることはありません。広告はありません。アプリ内課金もありません。
