## What is ShapeInfo Plus?

Feature
The ShapeInfo is useful application for calculating shape lengths, angles and area. You can get some calculated lengths and angles of the shape from choosing and entering values in the boxes upon the orange points. 

How to use
1. Choosing shape from the list.
2. Enter the value to the box upon the orange points. You can change the formation of the orange points by "NEXT" button (orange color) or tapping orange/gray point near the box that you are going to enter the value.
3. You can get calculated values of the shape, immediately after entering values.

Applications
- For the software developer, the mechanical engineer, the dynamics engineer and the surveying engineer.
- Study mathematics for high school students.

Functions
- Calculate lengths, angles and the area for the right triangle, the triangle, the sector, the circle and ellipse.
- Calculate volume for the triangular pyramid, the triangular prism, the circular cone, circular cylinder and the sphere.

### 4/5 — 挺方便

*2026-07-27*

要是能加入长方形和菱形就更好了

### 5/5 — Best Application for complex geometry

*2026-06-07*

Hi This one is clearly the best application for the geometry. I’m doing staircase and some hard stereotomy geometry. I use it easily each day. With my measuring tape, that app is the most useful tool in my arsenal to complete the job. 
And  for that, i’m deeply greatful. 
Merci Beaucoup! 

    心より感謝申し上げます

### 5/5 — Fantastisch

*2026-04-22*

Was mir nur noch fehlt ist die Berechnung von Kreisausschnitten.
Ansonsten wirklich sehr anschaulich und übersichtlich aufgebaut

### 3/5 — 丸め処理について

*2026-03-19*

丸め無いというのも入れて欲しい

### 5/5 — ShapeInfo Plus

*2026-01-29*

Für mich sehr hilfreich. Man kann in der Örtlichkeit sofort die gesuchten Werte ermitteln.

### 4/5 — Zuerst nicht verstanden…

*2025-11-17*

Die Art der Eingabeaufforderung ist ohne Erklärung etwas verwirrend. Man muss ein wenig probieren, um die Logik zu erfassen. Aber dann ist es ein nützliches Werkzeug. 

Ich würde mir wünschen, dass sich bei Veränderung der einzelnen Werte auch eine Veränderung der Figur bzw. des Volumenkörpers abbilden würde. Dann hätte man auch eine visuelle Kontrolle der eingegebenen Werte und ich kann erkennen, wie die Figur aussieht…

### 5/5 — 直角三角形

*2025-06-24*

長さa20、長さb10の1:2:√3 の直角三角形で角度が30度と60度が表示されない。

**Developer response:** 長さb10、長さc20を入力していただくと1:2:√3 の直角三角形で角度が30度と60度が表示されます。

### 2/5 — Poor value

*2025-03-29*

Dose not work well with one length and  2 angles

### 3/5 — язык

*2024-12-11*

как поменять язык, стоит по умолчанию китайский

### 1/5 — Bringt nichts

*2024-11-16*

Bringt nichts
