数字をひとつ入れるだけで、関連する単位がいっぺんに並びます。 「1820mm は何尺だっけ」「30m² って何帖」を、変換先を選ばずに確かめられる電卓です。 ■ 入れた数字が、全部の単位に同時に出る 長さは mm・cm・m・寸・尺・間。面積は m²・坪・帖。 どちらを見ているかは入力した単位で決まるので、モードを切り替える手間がありません。 結果を押せばその単位で入力し直せて、長押しでコピーできます。 ■ 単位を混ぜたまま計算できる 「1尺 + 300mm」のように、違う単位を混ぜて足し引きできます。 「1820mm × 3」のような倍率の計算もそのまま。寸法の積み上げに使えます。 ■ かんたん/プロの2モード かんたんは cm・m・m²・帖・坪だけ。部屋探しやDIYなら、これで足ります。 プロに切り替えると寸・尺・間が加わり、455 / 910 / 1820 / 2730 / 3640 のボタンが出ます。 一度切り替えれば、次からそのモードで開きます。 ■ 帖の基準を選べる 同じ広さでも、畳の基準が違えば帖数は1割以上変わります。 初期設定は賃貸情報でおなじみの不動産表示(1帖=1.62m²)。 設定から京間・中京間・江戸間・団地間に変えられて、いまどの基準で見ているかは画面に出ています。 ■ 桁は単位ごとに整えてあります mmは整数、mは小数3桁、尺・寸は3桁、坪・帖は2桁。 「1820.000 mm」のような読みにくい表示になりません。 換算は計量法の定義(1尺=10/33 m、1坪=400/121 m²)で計算しています。 ■ よく使う数字を残せます 計算した値は履歴に20件まで自動で残ります。 星を付けたものは、流れて消えません。 ■ iPadでは左右2列 左に入力とテンキー、右に結果一覧。広い画面がそのまま見やすさになります。 ■ アカウントは要りません 計算は端末の中だけで完結します。入力した値が外へ送られることはありません。アカウント登録も不要です。 画面のいちばん上にだけ広告が出ます。テンキーのそばには置いていません。広告の読み込みのときだけ通信します。 すべての機能を無料でお使いいただけます。 ■ ご注意 表示される数値は単位ごとに桁を丸めています。加工や発注の寸法としてそのまま使わず、必要な精度はご自身でお確かめください。 「間」は計量法どおり6尺(約1818mm)として計算しています。関東間の1820mmとは異なります。 本アプリの計算結果は、設計図書・見積書・確認申請などの正式な書類ではありません。

Verdict

The call

The clearest difference is in-app purchases: Genki Studio at none against 建築電卓's 1. Genki Studio also leads on ads (none vs shown). 建築電卓's advantage is update cadence (every 5 days vs every 6 weeks). On price, device support and iOS requirement there is nothing between them.
