Will Shipping Rates Calculator+ display shipping rates on the product page?

Shipping Rates Calculator+ can display shipping rates on the cart page and on most pop-up/drawer carts but it can't display them on product pages.

The reason is that the app uses the Shopify Ajax API (https://help.shopify.com/themes/development/getting-started/using-ajax-api) to get the shipping rates and this API is only able to provide shipping rates for the cart contents, not for a particular product.
