How to check your Shopify store on mobile (the 5 things that break)

A store can work perfectly in a desktop browser and still lose mobile shoppers. Many themes build the phone menu separately, and small screens leave less room, so a popup or a chat bubble can cover the one button that matters.

The 5 checks

• Open the menu (the ☰ icon) and tap every item, including the ones inside sub-menus. A link can be broken here and fine on desktop.
• Open a product and make sure nothing covers Add to cart: chat bubbles, "Get 10% off" popups, cookie banners, WhatsApp buttons.
• Pick an option (size, colour) and add to cart with your thumb, not a mouse. Tiny tap targets are easy to miss.
• Open the cart and check that checkout opens. Stop before paying.
• Scroll to the footer and tap your policy links and social icons.

Use a real phone

Your browser's mobile preview is a good start, but popups, app widgets and the phone menu behave differently on a real device. Check on your own phone at least once after every change.

If a popup covers Add to cart, look in that app's settings for a delay or a "don't show on product pages" option before removing the app.

Check both, every day

BugRadar opens your store every day in a desktop browser and in a mobile browser, and tells you which one broke, so a problem that only exists on phones doesn't go unnoticed.
