I'm Confused!

Among the potted plants I brought indoors in recent weeks is the plant I picked up on someone's front sidewalk because it was marked "FREE."

It has thick rubbery leaves and I assumed it was a rubber plant...

I trimmed off several limper leaves and took this picture of it. 

A few days later, I was surprised to discover that an app on my phone had identified it as a "Blushing Philodendron." I typed "Rubber Plant?" in the comment space - but nothing further has happened... so I'm still confused!  

I looked up "Blushing Philodendron" and found a picture of this plant - which doesn't really look like the one I have. For one thing, the leaves aren't as thick and rubbery.

Another test will be if the plant survives the winter in my drafty porch - a philodendron apparently doesn't like drafts!
