Please let me know what you think of the article and feel free to suggest improvements. There isn't currently a lot of information available about designing icons for the Apple Watch so I'm sure there will be some corrections needed. Thanks, Scott (Iconify.it)
I'm a little confused by the table presentation. Are @1x assets really needed for the apps, or are you just using that to show comparative sizes? If the latter, wouldn't it be easier to use "pt" here?
Hi John. Honestly, I'm not sure. I don't /think/ they are needed for the app since the display is retina, but I was following Apple's Human Interface Guidelines for a lot of the information and interpreting it as best I can since nobody has the actual device yet. Once we get a watch or when I can get definitive information from someone who knows for certain I will update the article. Sorry I can't be more helpful. I think we have compiled the most comprehensive information on the subject to-date but we're still shooting blind. But again, I /think/ the @1x are for relative sizes only.
Don't apologize, it's a great article & resource!
Thanks, John. I have received some great feedback and I'm getting ready to post a minor update to the article in a few minutes. Laura Reen, who is a talented iOS developer & icon designer from Estonia has been through the Apple Watch app submission process and offered some great edits. The updates should be live shortly.
Hi John, the updates are live. Specifically, the two changes are:
The app icons DO NOT get an alpha channel. This information changed in Apple's guidelines between the time I wrote the article and when it was published (about 3-4 days time)
I added information about Apple Watch app submission guidelines and the icon image required for the app store previews. See the "Pro Tip" in the article.
Kind Regards, Scott
