Co–Star Personalized Astrology

What Co-Star is and who it suits

Co-Star is an astrology app that centers on relationships. It is listed under Books & Reference on Google Play and carries a Teen content rating. The developer says its readings draw on NASA data.

Most of the app revolves around two things: reading your own horoscope and birth chart, and comparing those charts with other people's. It suits people who already read astrology and want it applied to friends, partners or a crush.

Daily horoscopes and notifications

The app provides personalized daily horoscopes. It can also send push notifications each day that are built from that day's horoscope, so the reading reaches you without opening the app first.

Comparing birth charts with friends

You add friends to the app and compare your natal charts, which produces a compatibility reading between the two of you. The listing places this among the standard features rather than the Premium ones.

The comparison is the main social feature. It gives a way to talk about astrology with a specific person instead of reading a generic sign description.

Learning to read your birth chart

The app includes lessons on reading your entire birth chart. This lets you interpret the chart yourself rather than relying only on a summary of what it says.

Premium charts, love reports and couples guidance

The Premium set adds three features. You can see the full natal chart of someone who does not have the app. You can also get a complete personalized report on how you love and why.

For couples, Eros gives guidance on everyday relationship situations, based on the zodiac compatibility between the two people. These features sit under a Premium heading on the listing, separate from the standard features.
