Hi John,
sure, but maybe a custom smartstore plugin is a better way to connect many app users to your shop, without api overhead and performance issues. This should be discussed with a developer from us.
This is a more business-related question: Do you really need an app? Customers have to install it on their mobile device. A major hurdle. Often not worth the app development effort. Do you believe, that they will install it in large enough numbers?
On the other hand, Smartstore has a great mobile web interface.
Greetings, Stefan
