Who it is for
Astrology readers who work with the same set of charts repeatedly rather than asking one-off questions.
12andus Astrology
Natal charts, transit forecasts, and relationship astrology
Overview
What 12andus Astrology does
Chart calculation is the core of this app: natal charts covering planets, houses, aspects, and retrograde positions, worked out from a birth date, time, and place. Where the birth time is unknown, the record says the system falls back to interpretations that do not depend on house positions.
Beyond the natal chart it produces transit forecasts running from a single day out to a full year, synastry between two charts, composite charts for a pair, and transits to those composite charts for relationship timing. The relationship material is not limited to romance and is described as applying equally to family ties, friendships, and business partnerships.
Up to fifty sets of birth data can be stored on an account so readings can be rerun without entering the details again. Apogeeks Pte. Ltd. is the developer.
What stands out
Stored birth data for up to fifty people makes comparisons and timing questions between named individuals repeatable.

Where 12andus Astrology is listed
12andus Astrology is listed in the ChatGPT apps directory only. Apogeeks Pte. Ltd. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
