Tutorial for creating companion apps?

I'd like to do some personal project that would involve writing an app for my device (Fenix 5Plus) and a companion app.

I am a newbie in this area...

I think I need to start to find the following information:

* When do I need to have a companion app?

* What SDKs do I need to use (both on the phone side and the device side)?

* Are there any constraints when writing the companion app (for example: can I use, React Native, Swift, or do I need to use C)?

* Are there any example apps out there?

Are you aware of some kind of tutorial that has some of that information in one place?

If not, would you suggest me a place/links to start?

I browsed through some of the Connect IQ documentation already (Connect IQ Basics, Reference Guides) and examples in https://github.com/garmin/connectiq-apps.

They seem to be targeted towards the wearable device, not the phone...

Thanks in advance,

Karol

The disk golf sample in the link you posted has an Android companion app.

So, I have an answer from jim_m_58 about an example of a companion app.

Does anybody have some info on tutorials? Or answers to the questions I posted?

On the other hand, do you think such a tutorial is worth having?

While I am preparing for my project, I could collect the info I gather -- but if there is demand for that.
