What apple is this

I planted this tree two years ago. Thought it was a red delicious, thought that was what the tag said when I bought it from Home Depot.  This is the only Apple on the tree.  Took the picture on Sept 15. Is this a red delicious or a different Apple.

Thanks in advance.

The apple looks more MacIntosh-y than Red Delicious-y to me.

thank you John.

Here are some other pictures

my honeycrisp look like that. what color is the flesh? honey crisp is yellowish, macs are white with some red streaking sometimes.

Here is when I cut into it. Honestly I think it was harvested to early.

yep. looks like a mac to me . honey crisp is more yellow. but I've never picked my honey crisp under ripe either. mac is a great apple too. my father has a mac tree and he harvests when a frost has hit them for best flavor. we're in zone 3b tho.

Thank you.  I'll see what it does next year.  The apple tasted really tart.
