You might not need this plugin. Its core job is small enough to live in your theme's functions.php.

Show the snippet

// Add a custom meta box for the body class field
add_action( 'add_meta_boxes', function () {
    add_meta_box( 'custom_body_class', 'Custom Body Class', function ( $post ) {
        $value = get_post_meta( $post->ID, '_custom_body_class', true );
        echo '<input type="text" name="custom_body_class" value="' . esc_attr( $value ) . '" style="width:100%">';
    }, [ 'post', 'page' ], 'side' );
} );

// Save the meta value
add_action( 'save_post', function ( $post_id ) {
    if ( isset( $_POST['custom_body_class'] ) ) {
        update_post_meta( $post_id, '_custom_body_class', sanitize_html_class( $_POST['custom_body_class'] ) );
    }
} );

// Inject the class into the body
add_filter( 'body_class', function ( $classes ) {
    if ( is_singular() ) {
        $custom = get_post_meta( get_the_ID(), '_custom_body_class', true );
        if ( $custom ) {
            $is_mobile = wp_is_mobile();
            if ( str_starts_with( $custom, 'mobile-' ) ) {
                if ( $is_mobile ) {
                    $classes[] = sanitize_html_class( substr( $custom, 7 ) );
                }
            } else {
                $classes[] = sanitize_html_class( $custom );
            }
        }
    }
    return $classes;
} );

Keep in mind:This snippet handles one class per post; the plugin may support multiple space-separated classes or custom post types beyond post and page.
