Hi Product Hunt! 👋
Sidera connects the parts of astrology that usually live in separate tools: your birth chart, daily calendar, personal transits, and relationship compatibility.
Choose an activity to explore its calendar, follow the bigger cycles in your transit timeline, or open a connection to compare both charts. When you have a question, the AI chat carries the relevant day, chart, or relationship context with it—so you don't have to explain everything again.
You can use Sidera on the web or Android, with a free tier and optional Pro features. The aim is to make astrology easier to explore and use for reflection, while leaving decisions in your hands. The gallery shows example readings; your results depend on your details and selected system.
I'd love your feedback: is the calendar clear, do the explanations make sense, and what would make the AI conversations more useful?
Thanks for trying Sidera!
