SleepCloud is an add-on for Sleep as Android, an application that allows users to track their sleep patterns. SleepCloud provides a new cloud service specifically designed for sleep data, offering full backup of sleep graphs, sleep data in your browser, and 2-way synchronization of sleep data between your devices. This add-on also allows for automatic upload of new sleep graphs after tracking, synchronization between multiple devices, automatic backup to SD card and comparison of sleep habits around the world by country.

SleepCloud has connections with 3rd party services such as Zenobase, FitnessSyncer, Fluxtream or Nudge, allowing users to correlate their sleep with data from other sources, such as Fitbit, RunKeeper, Strava, Foursquare, Last.fm and others. This makes it easier for users to keep all their data in one place and to analyze it more effectively.

SleepCloud is free to play when synced once per week. Full access is available through a yearly subscription with ~$4, which helps cover the monthly costs of running the service online. Also, users can connect with SleepCloud and help anonymously in research projects to find out more about the mystery of sleep.

Overall, SleepCloud is a useful add-on for Sleep as Android users who are looking for a reliable and secure backup solution for their sleep data.
