Cocoafish provides it's own kind of CMS to be able to add, edit, and remove content from an app. For example you could add new photos to an album for a restaurant, or update the address of the restaurant through
cocoafish.com. I suggest that you create the app using a separate Cocoafish account for that client, so they can have access to the data for just that app. If there are CMS features missing from
cocoafish.com that you think would be useful, please let us know.
Coming soon we are also going to provide the ability to create an administrative user for the app which can access all data. Therefore another option for providing a CMS for your client's app would be to create a custom website that uses the Cocoafish API as the administrative user to update content for that app.
