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.

I used to have this app for a time and just recently decided to come back to it after a long break. It would not allow me to log in through FB. It recognised I had an acc, requested permission through FB, and then redirected me back to the same login page. Over and over. I didn't have FB app so I even got that to troubleshoot - still no login. Faulty for being unable to access existing account. Not a good enough app for me to care to try more

App has been repeating info consistently zero depth to it. I used to recommend this app regularly, but that is no longer the case. It has shifted from feeling personal and insightful to repetitive, AI-generated content that lacks the originality it once had. It no longer reflects the Co–Star I originally chose. I’ll be switching to an astrology app with readings from an actual human astrologer instead. I’ve recommended this app to many people in the past, but I won’t be doing so anymore.

To put it simply, my mouth is agape with my chin on the floor! Like a character in cartoons, completely dumbfounded! I clicked a button a couple of times, which led me to pay seven dollars, something I cannot afford right now with everything. Luckily, oddly enough, I had Google play POINTS to purchase 25 queries in the 'void'. To receive a DIRECT, INFORMATIVE AND USEFUL answer to something I couldn't tell a counselor in years of sessions. Truly blown away! F** amazing. GO CO⭐!!
