Apple tree help

I’ve had two apples trees for 5 years now. Each year, both start off great in the spring but then by late June/July start developing yellow spots that end up stunting any further growth. I haven’t had any apples come as a result. 

This year, I started applying a copper fungicide at first bud in the hopes of fending off the annual disease. Now, I’ve got about 10 apples already growing. But I’m starting to see a few leaves with the yellow spots again. Any help/guidance much appreciated! I live in CT, the trees get full sun for a good portion of the day, and are watered regularly.
