How this is made
These horoscopes come from the real sky. They are not written in advance. Prism calculates where each planet is every day. Then it reads the sky in the traditional way for sun signs.
A birth chart has twelve houses. Each house is an area of life, such as money, home or career. For a sun sign, Aries is the 1st house, the next sign is the 2nd house, and so on. So every planet is in one house for Aries. The Moon’s house sets the focus of the day.
A planet is in a helpful position when it makes an easy angle with the sign. It is in a difficult position when the angle is tense. Venus and Jupiter usually help. Mars and Saturn usually add pressure. A planet is retrograde when it seems to move backwards in the sky. Tradition reads this as a time to review rather than to start. New moons are good for starts, full moons bring things to a peak, and eclipses mark turning points. Together, these give the day one of Prism’s five colours, from Hard to Harmony.
A sun sign is one twelfth of a birth chart, so this reading is the same for everyone born under it. The Prism app reads the same sky against your whole chart. Astrology is for reflection and fun. It is not advice.
