+Phobos is a small, irregularly shaped object with a mean radius of 11 km (7 mi),[1] and is seven times more massive than Deimos, Mars's outer moon.

+
+- (BOOL)application:(UIApplication *)application
+  didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
+     Phobos *client = [Phobos clientWithAppName:@"appname" channelId:@"appchannel"];
