Sidera
Your birth chart, calendar, and AI astrologer in one app
Turn your birth chart into a calendar you can explore. Compare dates for specific activities, follow personal transits, and explore relationship compatibility. Ask an AI astrologer about a day, placement, or connection with the relevant chart context already included. Available on web and Android. Free to start, with optional Pro features.
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?

Who hunted Sidera?
Sidera was hunted by Johnny Kartakov. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
