I have 4 apple trees they each have some leaves that look this way. I’m in zone 6b WV.
That looks normal to me, but I’m only comparing to my own trees, which are low organic spray. Some turn brown, some yellow, some spots, some just seem to shade from green to brown.
Looks like CAR to me.

Is it car? On the underneath side there will be tendrils if it is car. Looks more like frog eye spot. There are experts here that will give a more definitive response
@Buckeye thanks
@krismoriah thanks for the help. Is Car common this time of year?
@ansayre thanks i didn’t see any tendrils on the undersides. The leaves are smooth on both sides
I’m getting grubby tore up leaves now. But certain rootstocks defoliate early like P.2 as well. Earlier I clear erred and mixed two sprays by accident for leafspot. Burnt the tar out of the leaves. But the leafspot left.
