If you are using a food processor to chop and mix the apples and nuts, pulse them rather than leave the processor on. That way, you have more control over the size of the pieces.
Charoset tastes even better if you let the flavors meld together for a few hours before serving. Apples turn brown on the outside when exposed to air. If you prefer to keep your chopped apples light-colored, sprinkle a little fresh lemon juice on them before adding other ingredients.
It's easy to double, triple or even quadruple the recipe. In that case, consider using more than one type of apple to add depth of flavor.
If your apple is very large, you may want to increase the other ingredients to compensate. If the apple is very sweet, use less sugar/honey or add a few drops of fresh lemon juice.
