Natal chart and relationships
Co-Star turns a birth chart into a daily astrology feed. Users can add friends, compare charts, and read compatibility notes instead of reading a static report alone.
Daily horoscope feed
The app sends push notifications based on horoscope timing and keeps a direct, sometimes sharp writing style. NASA planetary data, App of the Day recognition, and press mentions are all part of the product’s public history.
Public record
Co-Star is not a new app, but it shipped a May 2026 update and still has one of the largest public rating counts in this category. It remains a useful reference point for social astrology apps.
