It's the frameworks shop.
It adjusts your Xcode projects for the frameworks.
It uploads your frameworks.
Use the App
When you've found a framework, the App will add it to your Xcode project.
Each one is free for two days. So you can try it out.
Then, as you code, it's only 6p a day for each framework you use.
When your app is finished you pay no more, no matter how popular your app is.
Free.
For two days
And keep coding with it
