### 3/5 — iPad

*2024-09-28*

I love this App on my iPhone, it doesn’t work on my M4 iPad though…

### 5/5 — Gas compositions

*2024-09-25, version 1.4.0*

When using a gas function that requires a composition, I cannot get the app to load the new analysis that I want for the calculations. I used to be able to do that but now I cannot.

### 3/5 — Requires Registration

*2016-02-21, version 1.2.1*

Looks comprehensive. However, most functions require (free) registration. The app claims that your information will be treated confidentially, but there's no explanation of what it will be used for. If you follow the link to Spirit IT's web site, there is a privacy policy, but it doesn't appear to apply to the app.

### 5/5 — FC

Great App. ! Super flow computer.
