Shopify public apps are usually seen as a boon to the newbie Shopify store owners. There is an array of applications available on the shopify app store, which are helping them boost their productivity in terms of better user engagement, usage of analytics for their sales performance, social media branding, and the list goes on and on!
But are these apps free? Not always.
Good and popular apps usually come with an associated cost and a billing cycle. If your company is into Shopify Application Development or, if you are a store owner who believes that your Private/Unlisted app can solve the generic issues of other Shopify eCommerce Store owners; then why not publish your App as Public and reap the sales profit out of it?
