Sidereal Watch

Track local sidereal time on Apple Watch with live location updates, a watch-face complication, and fast 13:30 sidereal alerts for observing or session work.

Sidereal gives astronomers, remote viewers, and consciousness explorers a fast, watch-first way to track local sidereal time.

Open the app and see your current local sidereal time instantly, calculated from your current watch location. Add the complication to your watch face for a quick glance before a session, while setting up a telescope, or when you want sidereal time always within reach.
