How does Currency Converter+ installation compare to other currency apps?
Currency Converter+ is the only currency app in the Shopify app store that features one-click installation.
That means that after installation the app is automatically up and running in your store. That's all you have to do if your store uses a free Shopify theme or one of the popular paid third-party themes. For other less common themes or themes that have been modified, the app will still work out-of-the-box but some configuration tweaking is preferred to make the most of the app.
All other currency apps in the Shopify App Store require either changing your Shopify currency configuration or to add some code in your theme templates.
