With a ton of iOS apps inevitably getting updates with iCloud and iOS 5 support today and over the next little while, we also expect to see Mac App Store apps incorporate the cloud functionality. While there doesn’t appear to be many live just yet, we did spot SingleText, which was just released and designed specifically for iCloud.

SingleText is essentially just a simple text box, allowing you to take notes and have them automatically stored in iCloud. The app doesn’t actually have any settings, simply enter your iCloud login and you’re good to go. You can then retrieve any text entered into the SingleText text box through the iOS app companion or any Mac with the app installed.

Both the Mac and iOS apps go for $0.99 each and are available to download now. We expect to see many more iCloud compatible apps popping up shortly.
