I see a lot of amateurs report star magnitude on astrophotos.
Is there software that does this reliably?

Specifically noticed a site that tracks supernovae and image contributors from various locations consistently report magnitude changes over days. I imagine they use some software to do this rather than by visual comparison to known stars.

Any suggestions on software that does that please?

Astroart 8 has excellent capability for scientific analysis of images, including measuring stellar magnitudes:

You should investigate about Photometry. This is a good place to begin https://www.aavso.or...hotometry-guide
