Triangle3 vs アングル加工
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Triangle3
This app provides advanced calculation tools for field work, specializing in right and unequal triangles. It supports complex shapes like cones, pipes, and screw wings, with AR visualization for floor plans. It also includes standard calculator functions and memory features.
- Right and unequal triangle calculations
- Complex shape development (cones, pipes, etc.)
- Augmented Reality (AR) floor plan visualization
- Standard calculator functions with memory
- Trigonometric and cosine theorem calculations
- PCD and screw wing calculations

This is a calculator application created by me, a canner, focusing on the functions of a calculator necessary for field work. Even if you don't understand trigonometric functions, you can easily calculate with this calculator. It can calculate right triangles and unequal triangles. It can calculate memory, answer memory, pi, repetition, parentheses, trigonometric functions, and cosine theorem. Develop cones (including misalignment), diagonal cuts, R-cuts, T-pipes, shrimp tubes, rounded corners, rounded corners (eccentricity), hopper eccentricity, pipes from mirror plates, connecting pipes to tapered pipes, screw wings, and calculate PCD. It is possible to display the development on the floor in full size with AR for a specific development. User's Manual ############################ Calculator section Press and hold the "ANS" button to display past calculation results. Tap the label of the calculation result (right after pressing =) to mark the value in the ANS list. Tap the white button to enter the value displayed on the label. Swipe the screen to the left or right to rotate the right triangle. Swipe the screen up and down to flip the right triangle. Enter two right triangles and three unequal triangles. Tap the "Cal" button to display the calculation result. Tap "Cl" button to clear the displayed value. You can also use the "0" label to erase only the specified locations. If you touch the button and slide it down, the numerical value of the calculation result will be displayed on the label, and can be used for the next calculation. Trigonometric calculations can be done with By sliding the [4] and [6] buttons, you can go back and forward. Pressing the CLR button once will erase the number. Press twice to reset the rotation. Press and hold to erase numbers, reset rotation, and erase memory. Press and hold to erase numbers, reset rotation, and clear memory. Automatic input of pipe outline Example 50A -> Input "5", "0", "1 slide". 1¼B -> Input "1", "4", "1" and "2 slides". Each slide twice in succession will reduce the value by half. Expansion section The input method is the same as in the calculator section. To expand a pipe, PCD, or mirror, slide the screen to the left or right to select the expansion diagram. Basically, all buttons need to be entered, but in some places "0" can be used. For round corners (eccentricity), double-tap the screen after entering the numerical value for round corners to switch to the input screen. Please enter the division of the circumference in multiples of 4. The calculation result is an image, so it may differ from the actual shape.

アングル加工は、アングル材(支持材)に配管をUボルトで固定する際の、 配管位置と支持材全長を自動計算する現場向けアプリです。 【主な機能】 ■ かんたん入力 配管隙間・アングル余長・管種(SGP/VP)・配管数を入力するだけ。 「全配管を同じサイズにする」トグルでまとめて設定も可能。 ■ 自動計算 配管位置・Uボルト穴の座標・支持材全長を計算。 余長不足や隙間不足は警告でお知らせします。 ■ 2D図面表示 アングル材・配管・Uボルト穴を実寸比で描画。 寸法線(並列・直列)、配管隙間、保温シェルの表示に対応。 ■ 固定モード 配管を直接ドラッグして位置を微調整。 寸法を直接タップして編集することもできます。 ■ 3D表示 立体表示で全体像を確認。指で回転・ズームできます。 ■ 保存・共有 計算結果をファイルに保存。一覧から呼び出し・共有が可能。 ■ 設定 配管サイズ別の標準径・Uボルトピッチをカスタマイズできます。

Verdict
The clearest difference is price: アングル加工 at Free against Triangle3's $3.99. Triangle3's advantage is update cadence (every 5 weeks vs every 38 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
