Whatis going on with my leaves?

It looks like you probably have a pest. Itβs difficult to tell from that photo, but blister mites are a possibility (attached an info sheet); however, it also looks like something was gnawing on those leaves and deforming them when they were young (shriveled green leaves), so something like aphids is also a very likely possibility.
Recommend searching for βapple tree pestsβ, then do an image search for βapple tree PESTNAME damageβ for each kind of pest and try to figure out what looks the most like what youβre seeing.
