I agree its scab. I never had that until last year on my pears when I got it really badly. This year I put down a disease spray post-bloom on all leaves (something I don’t normally do as the pears I usually only need to spray the fruits) and I don’t see any of it.
last year I also had some non-fruiting apples I did’t spray at all and they also got bad scab. This year I hit all the apples and there is only a spot or two of scab where I probably missed the spray.
