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.
SwiftStore scans your Shopify theme and identifies every factor slowing down your store. It detects render-blocking scripts, oversized images, unused CSS, and slow third-party app scripts. Once issues are found, you can preview fixes in a safe sandbox before applying them to your live store. The app runs image compression, script deferral, font preloading, and critical CSS extraction automatically.
