Co–Star Personalized Astrology

Co-Star uses NASA data to calculate the exact real-time positions of stars, interpreted by human astrologers working with AI to create personalized horoscopes and birth charts. It's not just predictions, but a tool for deep self-understanding and understanding others.

Add friends to compare natal charts and see your compatibility. Read personalized daily horoscopes, receive push notifications, and learn to read your entire birth chart. Premium features include viewing the full natal chart of anyone without the app, a complete personalized love report, and Eros for couples navigating everyday situations based on zodiac compatibility.

Twice named App of the Day and featured in the New York Times, Vogue, and Vanity Fair, Co-Star believes there are no bad zodiac signs, only complicated dynamics. It uses astrology as a framework for real talk in a sea of small talk.
