Caelus runs a real AI astrologer entirely on your iPhone. No servers, no tracking, no data leaves your device. Ever.
A real AI model (Qwen 3.5) runs entirely on your iPhone. No cloud APIs, no servers, no internet required after setup. Your readings are generated privately on your device.
Planetary positions calculated by SwissEphemeris with arc-second accuracy. No generic horoscopes. Every reading is grounded in your actual birth chart and current transits.
Zero data collection. No accounts. No analytics. No tracking. Your birth data, readings, and conversations never leave your iPhone. Your stars, your business.
Caelus is an AI astrologer that lives on your iPhone. She reads your chart, interprets the stars, and speaks to you in your language. Every reading is uniquely yours, generated in the moment.
Unlike cloud-based apps, Caelus never sends your birth data anywhere. The AI model runs locally on your device's neural engine, creating deeply personal readings in complete privacy.
Chat with Caelus about your chart, upcoming transits, relationship dynamics, career timing, or anything written in your stars.
Draw single cards, 3-card spreads, or Celtic Cross layouts. Every reading is connected to your birth chart for deeper insight.
