Caelus is interesting because it does not pitch itself as another daily horoscope feed. The main claim is privacy: the AI astrologer runs on the iPhone, with no account, no tracking and no server-side readings after setup.
The app covers chart-aware horoscopes, tarot, compatibility and chat. That makes it a good fit for users who want AI astrology but are uneasy about sending birth data and personal questions to a cloud service. The tradeoff is practical: the official page says it requires iOS 17 and a large local model download, so it is not the lightest option.
