What does "Remaining time" mean?
Currently, CloudOn is completely free and and there is no time limit.
In this first release, we would like to allow you to be more productive on the iPad. We are looking forward to your feedback so that we may better understand what you’d like to use CloudOn for.
At some point in the future, CloudOn may become a time-based service. For now, however, you can work in CloudOn as long as you’d like.
