There are no bad zodiac signs, only complicated dynamics. Co–Star uses astrology as a framework for understanding ourselves and our relationships; a shortcut to real talk in a sea of small talk.

This is then interpreted by real human astrologers who collaborate with AI technology to produce the birth chart and daily horoscopes you read in the app.

Over two years ago, I posted a review saying that it would be nice to finally get dark mode and the circular chart features on the Android version of this app. iOS has had those features for ages now, why not Android? And now, with this latest update... The UI on the app is even worse. The Home, Friends, and You navigation buttons are barely showing and are cut off. The top of the app is now going up into the notification section of my phone (Pixel 9 Pro). Terrible update.

I've had Co-star for a decent amount of time. At first, it was a fun little app to look at when I got curious or bored, but then I added my friends. I started delving into their charts and noticing patterns. Even in my own chart and daily insights. I know people don't put much stalk in astrology, but more often than not, it's worthing noting. At least for me. I really do enjoy this app immensely!

Favorite app. Love my daily updates and the originality they come up with. The paid in depth readings have been extremely insightful and eerily accurate and I love that they include daily friend updates as well. For friends or partners who don't have it, you can manually add them to your list. I've tried many of the options available on the playstore, by far, this is the only one I transfer to every new device. They also have a very helpful and happy staff and it shows they enjoy their work. 🫶
