Sleeping Time, if you are new, is a web app that lets you determine the sleeping pattern of any Twitter user as long as they have a public profile on Twitter (see sample report).
Sleeping Time launched in 2010 and since then, the app has been used to generate the sleeping schedules of more than 500,000 Twitter users. The response was unexpected and it even made it to the front page of a newspaper.
The app reads the time-stamp of the last 1,000 tweets of a Twitter user and then estimates their sleep cycle based on hours when he or she is least active on Twitter. To get started, sign-in with your Twitter account (it will never post anything to Twitter on your behalf) and enter the user name of any Twitter user to see their sleeping pattern.
Here’s what’s new /changed in Sleeping Time v2.0:
- The algorithm has been tweaked and the app should thus provide even more accurate sleeping estimates.
- Sleeping Time now sports a responsive design.
- Internally, the app is now powered by WordPress (PHP) while the previous version was on Google App Engine (Python).
- The app is better equipped to handle the limitations of Twitter API that go into effect next month.
