## What is Offset Calc App?

The app is used in the industrial pipe construction. 
European standard (EN 10220)

Functions: 
Calculation of offsets and
weight calculation of pipes, offsets and profiles. 

All nominal diameter and fittings are provided, so it will be very easy for you to solve complex calculations quickly. Even if you put in false information, you can not get wrong solutions. This way you can save material, time and stress. The App is your help in a hectic and busy working day.

- 28 offset calculations (8 offset types with 2 or 4 interrupts),
- Given nominal diameters (DN25-1000) according to EN 10220 with outside diameter (z. B. NPS/DN
100 - 114,3),
- Calculation with lenght or elbow angle,
- 4 types of elbow,
- Manual input of elbow radius,
- Offsets with tee,
- Individual gap,
- Detailed help and description,
- History of your calculations.

Results
- Cut length
- Elbow angle

### 5/5 — Das Problem habe ich auch . Höhen Seitensprung mit 2 Bögen ohne passsatück eäre ne Bombe .

*2026-06-24, version 1.23*

Wirklich tolle App.
Könnte man noch Etagen mit T-Stücken und verdrehte Etagen mit zwei Bögen hinzufügen. Oder fehlen mir nur die Fähigkeiten die App richtig zu nutzen 😂

### 2/5 — Eigentlich eine gute App

*2022-11-30, version 1.22*

Leider rechnet die App zB bei einer im Raum verdrehten Etage von Mitte Bogen zu Mitte Bogen, was in den meisten Fällen keinen Sinn macht, da man den Winkel und somit die Auslage noch nicht kennt. 
Kennt man nun den Winkel und zieht ihn von der Rohrlänge ab, stimmt der Winkel nicht mehr. 
Das ist meiner Meinung nach ein Ausschlusskriterium sich die App zu kaufen. Andere Apps machen das wesentlich besser, sind aber nicht so übersichtlich in der Darstellung.
Wenn das geändert werden würde hätte die App 5 Sterne verdient.

### 5/5 — Super!

*2020-04-30, version 1.22*

Tolle App. Sehr hilfreich
