Check 16 / 16 LOW impact Free
Add store favicons for iOS / Android / manifest
What this check is
A saved storefront looks different on iOS and Android: iOS reads the Apple touch icon, Android reads the web app manifest icons. Shipping only a 32px favicon leaves a blank tile on the home screen.
How to implement it
Generate 180x180, 192x192 and 512x512 PNG exports from the logo, reference them in the theme head as the Apple touch icon and in a site.webmanifest, and keep the background solid rather than transparent so the icon does not disappear on dark home screens.
How to verify it
Save the store to the home screen on both an iPhone and an Android device and confirm the icon renders at full size, without a white square or a cropped mark.
