Aviation App Idea

Dear Devs,

I'm seeking an activity or app geared towards flying safety for general aviation.  The activity would have the following data fields:

1. SPO2 %

2. Barometric Altitude

3. Elapsed time

4. Two time fields: Local and GMT

Such an app would be extremely helpful when flying general aviation aircraft to monitor hypoxia situations.

Is it possible to create a custom data field that access the SPO2 information?

Thank youl
