In a mixing bowl, combine the diced apples with lemon juice to prevent browning. Set aside.
In another mixing bowl, whip the heavy cream using an electric mixer until soft peaks form.
Gently fold in the softened cream cheese, sweetened condensed milk, and vanilla extract until well combined and smooth.
Incorporate the diced apples into the mixture, folding gently so as not to break up the apple pieces.
Pour the mixture into a freezer-safe container, smoothing it out with a spatula.
Sprinkle toasted coconut flakes over the top, pressing them in slightly.
Cover the container and freeze for at least 4 hours, or until the ice cream is firm.
Once set, scoop and serve in bowls, garnished with additional coconut flakes or fresh apple slices if desired.
