Ever wanted to serve a dedicated theme to visitors on handheld devices instead of a theme that is fine-tuned for big screen traffic?

Slim Mobile Theme Switcher is a highly optimized, lightweight plugin designed for websites that need to serve a different theme to mobile devices while preserving the primary desktop experience.

Instead of relying on clunky, resource-heavy device detection libraries, this plugin uses streamlined, modern user-agent detection to instantly route users to the correct theme before the page even loads.

Key Features

Three-way Theme Routing: Serve up to three different themes simultaneously. Set one theme for Mobile Phones, one for Desktops, and optionally enable a dedicated theme specifically for Tablets (iPads/Android tablets).
True Mobile Detection: Uses refined regex to separate small-screen phones from tablets (iPads/Android tablets).
Zero-Friction Setup: Select your themes from a simple dropdown menu. No coding required.
Manual Overrides: Allow users to manually switch between views using ?theme=handheld or ?theme=active or ?theme=tablet.
Persistent Choice: Activating the ‘Remember Visitor’s Choice’ option ensures that when a user has manually selected a different theme, this preference is saved for 30 days via cookies.
No Bloat: Zero front-end CSS or JS added by the plugin itself.
Developer Friendly: Built by a developer for developers.
