### 5/5 — Tuyauterie industrielle

*2020-03-14, version 4.0.6*

Je suis tuyauteur industriel et chaudronnier.
Dans ce milieu, les calculs trigonométriques sont assez fréquents.
Même si je pratique la trigonométrie régulièrement à la calculatrice, cette application m’a permise d’aller plus vite dans mes calculs pour réaliser mes pièces tuyautées ou chaudronnées

### 1/5 — Wrong result

*2022-12-22, version 4.0.6*

Very poor to think the app can not do basic calculation correctly

### 3/5 — Very Unclear Upgrade Options

*2023-07-12, version 4.0.6*

There are several options for upgrade! But nothing at all to identify a single additional feature, other than how many decimal places are added beyond 0.9. You want my money, give me a slightly better reason for why I should gov it to you, rather than another app that gives me a better representation of the triangle. There are others apps that are free and give you 10 decimal places automatically. 

This app will help you with basic trig. There are better ones out there for free. So you go into the scrap app pile!
