I really really liked the idea of sleepyti.me, but thought that the implementation might have been a bit lacking in style and simplicity, so I tried to remake this service in a form as simple as possible. In its current version, Vyspis supports 24- and 12-hour time formats with different syntax and keyword "tomorrow", but I am trying to add new features which will make the experience even better without accidentally making a new Wolfram Alpha.
