I’m researching this because the pipes froze and burst in our rental house last winter.
I found this article:

I haven’t studied it yet but there’s a lot of information.
I don’t know if app updates are significant. Possibly the manufacturer got it right and there’s no need to mess with it.
I would be more interested in the reviews on Amazon or Consumer Reports.
If you find something good I hope you let us know. Last year it wasn’t just the Frozen North that got frozen.
