What app can automatically adjust product price based on quantity?

Topic summary

Need for a Shopify app or method that updates the displayed total price directly on the product page as quantity changes. The specific goal is for the price shown to increase immediately when a customer raises the quantity, such as showing double the price when quantity is set to 2, rather than only recalculating in the cart.

Key point:

  • The request is about live price updating on the product page, not standard cart-based price changes.

Current status:

  • No app or solution is provided in the post.
  • The question remains open, with the user asking whether an app exists or if custom coding would be required.

Im looking for an app that will adjust the price as the quantity is increased on the product page, not just the cart. So when a customer increase the quantity to say 2, the price on the page automatically doubles.

Is there such a thing? Does anyone know how to do this feature? I figured Id ask here before I go to the coding forum
