Absolutely! After you purchase your icon set send an email to info@imaddbox.com to request extra iPhone icons for FREE. Any set that you purchase that is missing app icons, I will gladly add a few more for free so you can complete you iPhone aesthetic.
If you would like to purchase a custom iPhone set that I do not have available in my shop, you can email for pricing. I can also create custom iPhone widgets, and custom iPhone wallpapers, as well as custom Apple watch wallpapers or faces.
