I can't remember if I already had an option for iCloud sign in. Things I've seen so far:

• register (a bit annoying) 
• register using Facebook, then ask for email and password (what??) 
• register using Facebook, Twitter or google (not sure I like this for privacy) 
• and new for me: register using iCloud (read below)

At this point, I wonder: it's a free app, why would they allow me to be only a random ID ? 

And of course, the nature of this app is to get metrics from all your other account. So random ID ? Not so much. ​

The application in itself is quite nice, with AirPlay feature for a quick dashboard. But it's like.. Very...... V...e....r....y.... Sloooooooooow. Feels like my iPhone 4 when I'm using it on 3G.
