Measuring saddle tilt

in Workshop
I've got hold of an SMP saddle that I've yet to fit. Is there an (free) app that would allow me to determine the tilt on that (presumably by putting a ruler or similar on top as they are quite a weird shape)?

And a hard back book.
It's one of the capabilities in the measure app.
small spirit level from B&Q for a pound
It is hardly an exact science though. I use trial and error.
Sit
Nudge up or down until it's right.
In my experience different saddles need diff tilt, depending on padding, shape and bike .
The common issue is that different saddle models talk about referencing different parts of the saddle top to get flat/ slightly up/ slightly down.

I find because of the raised rear you have to set it so it looks like it is tilted down at the front slightly for it to be level , if that makes sense. I gave up with the spirit level and did it by eye and trail and error
Just go riding and take tools to adjust. I found on all of them that even a tiny tweak in position made the difference between a bit irritating to perfect comfort.
To look at they appear more nose UP than anything.

PL2 that's a really good idea to measure it once I get it right so it can be replicated on my other bike(s).
