Does the chat widget work on mobile?

Yes. The storefront widget is fully responsive, and the same theme app embed serves desktop and mobile. There's no separate mobile configuration and no second embed to install.

Most of your customers browse and buy from phones, and the widget treats the phone as the main case rather than an afterthought squeezed into a desktop layout. It adapts its sizing and placement so it stays readable and usable without covering critical storefront content, and buttons, message bubbles, and the input area scale for narrow viewports.

Touch, not just layout

Fitting the screen is half the job. Opening the widget, scrolling message history, typing replies, and submitting in-chat forms should all feel natural on a phone or tablet. This matters more than it sounds: if chat is hard to use on mobile, shoppers abandon the thread or email you instead, which defeats the purpose of live help on the product page.

Check it on a real phone

After enabling the Simple Chat app embed in your theme, preview the storefront on an actual device or your browser's mobile emulator. Confirm the widget opens, messages send, and the conversation persists as the customer navigates product pages. If your theme uses aggressive mobile CSS, spot-check a product page and a collection page. The widget should stay accessible without custom code on your side.
