Apples, too many?

below are pictures of apples on our trees. it seems to me that they are a bit too thick and that the crop might benefit from thinning, so i googled "apple thinning" and all the results were about spraying something on the flowers. well, i'm obviously too late for that and wouldn't spray poison on them anyway. my only previous experience with apple trees was in an orchard long abandoned and untended for many years. twenty or so trees of a wide variety produced lovely luscious apples with zero help from humans. i ate a lot of delicious apples. tasty delicious, not variety delicious, tho some may have been.

so i would be grateful (tho not yet dead) for any advice any of you may have from your experience of apple cultivation.
