I can handle a small amount of apple and once or twice a year I will make apple crisp and eat it with lots of whipped heavy cream. My bgs seem to be OK with a small serving. The one problem with too much fruit is the fructose. The spike may not appear on your meter but fructose is processed in the liver and may make you more insulin resistant if you eat too much of it. I wouldn't think an apple here or there would hurt though.
