Local Sidereal Time
iOS Universel / Utilitaires
Sidereal helps you track local sidereal time from your current location or any place you want to check. It is designed for people interested in the 13:30 LST window discussed in remote-viewing literature, while also supporting any custom sidereal target you want to follow.
Use Sidereal to:
View a live local sidereal clock based on your current location
Calculate local sidereal time manually from longitude, date, and time
Search for a city or address and see the result with map support
Generate the next 31 upcoming hits for your selected sidereal target
Schedule the next 30 days of on-device alerts
Export future times to CSV and export events to your calendar
Customize your target LST, alert timing, full-window notifications, night viewing, and map visibility
Sidereal starts with 13:30 LST as the default target, but you can change it in Settings to track any local sidereal time. The app includes a trial, with Pro unlocking continued access to advanced tools and planning features.
