A number of readers have noted that the app is no longer available in the App Store, and a note posted on the company's website indicates that it is currently "sold out".
Thanks for your support of CloudOn! We're currently sold out. We look forward to the feedback we will receive as we continue to support the many users that have registered in this first phase. If you missed out on our first release, please sign up here.Given the publicity the app has received and its price tag of free, it is unsurprising that the company has apparently experienced a significant amount of interest from users. And with the actual service running on CloudOn's own servers, it is likely that that demand has simply outstripped the company's server capacity.
