Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureYour store looks perfect on your phone, but your customers use dozens of different devices. Sellwise Mobile Preview renders your storefront on 26 device profiles, including real Safari for iPhone and iPad, Android phones, landscape mode, and foldables. It highlights broken layouts by naming the exact element causing horizontal overflow, and flags JavaScript errors and resources that fail to load.
Theme updates break stores quietly. A header shifts, a button disappears, an image stops loading, and nothing tells you until sales drop. StoreGuard checks your storefront every time a theme is edited or published. It shows your live store next to the draft theme, page by page, with changed areas marked and traced back to the section they came from.
