Mac: If you're an iPhone or iPad user, you know how nice it is that iCloud manages to sync all your Safari tabs across computers. Unfortunately, that's not really useful if you don't use Safari on your Mac. CloudyTabs is an app that sits in your menubar and shows you all your open tabs on different devices. Click on one, and it opens in your default browser on your Mac.
Once CloudyTabs in installed, you'll see a list of all your open tabs on any device using iCloud. When you click on one, it will open up in your default browser. This is great if you use Safari on your mobile devices and Chrome or Firefox on your desktop. Chrome has had this feature for a long time, but if Chrome's too slow on your iOS device for you, this is a nice way to still use the tab-syncing option without resorting to using Safari.
