The Real Differences

Co-Star gives you a daily notification with a generic sentence. Celestia lets you ask follow-up questions, explore your chart, and get personalized advice about your actual life situation.
Entertainment vs Understanding
Co-Star is designed to be entertaining and shareable. Celestia is designed to help you understand yourself. Different goals, different results.
