Enter a birth date and place, plus the time if you know it, to see a tropical birth chart with planet placements and a seven-section written reading. The chart and full natal reading are free without an account. If the birth time is unknown, Celestio leaves out houses and the Ascendant rather than assigning a guessed time; a Moon sign that may change that day is treated as uncertain. Charts normally use Placidus houses, with Whole Sign used where Placidus cannot be calculated.
The separate compatibility tool compares two charts for a partner, friend or family member. Its preview shows the strongest connections for free; the full written relationship report costs a one-time US$2.99–14.99 depending on country, with the exact price shown before payment. An optional account lets you save readings. Readings stay private until you create a share link, and the site publishes guides to signs, houses and chart reading. The interface and readings are in English.
