Apple scooped up a beloved mobile application with plans to fold it into its own offering. Dark Sky sells for $3.99 and is popular due to its hyper-local forecasts. It's important to point out that the app is popular not only with iPhone owners, but also with Android owners.
Last month mobile-to-mobile communications company Bump decided to share its technology, which allows for data transfer between two iPhone or Android phones. For example, its flagship iPhone app swaps contact info and photos when two phones "bump" (as in "fist bump") near each other. Bump introduced an API, but to little fanfare.
Magickly aims to make image manipulation possible as a simple web service. The Magickly API is very easy to use, and completely open source. It requires no API key, and allows a developer to use a lot of different image manipulations on any web-accessible image. Magickly is an open source, simplified version of the Aviary Effects API, which has a contest ending next week.
