Pusher
OS X and iOS application and framework to play with APNs
Pusher is a Mac and iPhone app for sending push notifications directly to the Apple Push Notification Service (APNs). Testing push notifications for an iOS or Mac app normally requires setting up a server or creating an account online. And when these don’t work properly, it can be very difficult to find out why. With Pusher all you need is an SSL certificate and a device token, and you can start pushing directly from your Mac and even from your iPhone! Pusher provides detailed error reporting and logs, and many other tools. It’s got a small framework for both OS X and iOS, and is a good choice for better understanding how push notifications work and playing around with them.
