Almost every mobile app developer has to fetch (or update) data from a remote server via remote APIs. The mobile app under development is tightly coupled to a) the existence of these remote APIs, b) the stability/reliability of the APIs, and c) the types of data that is returned from the APIs.
Unavailability/unreliability of APIs leads directly to a significant loss in developer productivity.
Using an intuitive UI, changes can be made quickly, and are effective immediately, without the need to stop, recompile the app, and resume again. ServeUp responses are able to easily be shared multiple mobile and desktop platform apps.
