Co–Star Personalized Astrology

Co–Star is an astrology app that uses NASA data and human astrologers to provide a unique perspective on your personality and relationships. It has been featured in the New York Times, Vogue, Vanity Fair, and more, and has been praised by celebrities like Dua Lipa.

The app lets you add friends to compare your natal charts and see your compatibility. You can read personalized daily horoscopes and receive push notifications based on your sign. It also teaches you how to read your entire birth chart, offering a deeper understanding of yourself.

Premium features unlock additional insights, such as viewing the full chart of someone who doesn't have the app, getting a complete report on how you love and why, and using Eros, a feature designed for couples to navigate everyday relationship situations based on zodiac compatibility.

Co–Star uses astrology as a framework for understanding ourselves and our connections, turning small talk into real conversation. There are no bad zodiac signs, only complicated dynamics, and the app helps you explore those with clarity and precision.
