Also Included In
Zodiac Wheel is an astrological instrument that runs entirely on your iPhone. No account.
No subscription. No server. No internet connection of any kind.
The celestial engine is on the device. Every planetary position, every aspect, every retrograde and every birth chart is computed from first
principles as you look at it, using the same Keplerian elements published by NASA's Jet Propulsion Laboratory and the algorithms in Jean Meeus's
Astronomical Algorithms. Nothing is fetched. Nothing is looked up. Nothing about you leaves the phone, because nothing about you is sent
anywhere in the first place.
THE WHEEL
The twelve signs around a wheel of the year, with a hand at the Sun's true position and every body standing at its own degree. Tap any sign to read what it means and see what is standing in it right now.
And then you can run it. A shuttle under the wheel drives the whole sky forwards and backwards, from an hour a second to a season a second, and
lets go back to the present. Watch Mercury slow, stop and turn. Watch the Moon go round in a few seconds of your thumb. Nothing that fetches its answers from a server can do this, because the engine is on your phone rather than on somebody's machine.
THE SKY
What is actually happening overhead, right now. Every aspect in force with its exact angle and orb, and whether it is applying or separating. Retrogrades with the dates either side. Most apps give you a mood. This gives you the geometry the mood came from. Run the wheel and this moves with it, so you can read the sky of any date you like.
THE CHART
A full birth chart from a date, a time and a place. Sun, Moon, Ascendant and Midheaven, every planet in its sign and house, and the complete aspect grid. Whole Sign, Placidus or Equal houses, whichever tradition you work in. Historical time zones are handled properly, so a birth in a daylight-saving week forty years ago resolves to the right hour, which is the detail that moves an Ascendant by a whole sign.
THE REFERENCE
Twelve signs, ten bodies, twelve houses and five aspects, each with what it signifies in the tradition. Searchable, and written to explain rather than to predict.
Works in an aeroplane. Works in a basement. Works in ten years when the servers behind other apps have been switched off.
One price, once. No adverts, no tracking, no analytics, no in-app purchases.
Zodiac Wheel has been rebuilt from nothing.
The old app drew you a wheel. This one runs an ephemeris. Every planetary position, every aspect, every retrograde and every birth chart is worked
out on your iPhone as you look at it, from the orbital elements published by NASA's Jet Propulsion Laboratory. No account, no subscription, no
server. The app never touches the network at all except to turn a birth place into coordinates, and you can type those in yourself instead.
THE SKY
A new tab for what is actually overhead right now. Every aspect in force with its exact angle and how far inside orb it sits, whether it is closing
or separating, and every retrograde with the dates either side. Most apps give you a mood. This gives you the geometry the mood came from.
THE CHART
Full birth charts from a date, a time and a place, drawn round with the houses, the angles and the aspect web. Whole Sign, Placidus or Equal,
whichever tradition you work in. Historical time zones are handled properly, so a birth in a daylight-saving week decades ago resolves to the right hour, which is the detail that moves a rising sign.
THE REFERENCE
Twelve signs, ten bodies, twelve houses and five aspects, each with what it signifies in the tradition. Searchable, written to explain rather than
to predict, and newly illustrated throughout with engraved plates.
A HOME SCREEN WIDGET
The sign the Sun is in, the degree it has reached, and the date it crosses into the next one.
The eight sabbats are no longer part of this app. They have a home of their own now in Wiccan Wheel of the Year, which does that job properly.
One price, once, as before. Everyone who already owns Zodiac Wheel gets all of this free.
