The Optimizely iOS Sample Code by Optimizely allows API interaction with the aim to make experiments inside the application. The example has the objective to optimize the performance of application development.
Kippt, designed to make information workflow and archiving effortless, has launched a new API alongside a developer site and app gallery. The new, publicly available API simply opens up the existing Kippt API that continues to power the Kippt web service. Instead of pushing Kippt as a standalone product, the Kippt team hopes that the Kippt API will encourage developers to develop apps based on the Kippt platform.
