About Astroappy

Astroappy offers accurate, fast and free astrology calculators, with guides that explain what the results mean.

How the calculations are made

Planet positions, house cusps and aspects are computed by our calculation service from the NASA JPL DE440 ephemeris. Your birth time is converted to universal time using the birth place's own time zone, including the daylight-saving rules in force on that date, so the same details give the same chart on every device.

Content

The guides on the blog and on each calculator page are written by our authors and updated regularly.

Why the site is so light

Pages are built on the server, no JavaScript is sent to your browser, and system fonts are used, so the site opens instantly even on slow connections.

Turkish edition

The same calculators are available in Turkish on Burcapp, our sister site.
