The Moon, properly: phase, sign, aspects and both lunar-mansion systems, from real positions.
Selene shows where the Moon is and what it is doing: its phase on a live dial, its sign to the arcminute, how lit, how old and how far away it is, moonrise and moonset for your city, the next Full and New Moon to the minute, and every aspect it makes to the planets.
Add your birth date, time and city and it reads the Moon in your own chart: its house tonight, your birth Moon on a natal-and-transit wheel, your progressed Moon, and the nakshatra and mansion you were born under. The readings are written into the app, not generated. Every screen comes in three themes: midnight, neutral dark and pearl day.
One typeface, flat panels with thin borders and a deeper midnight palette, so the sky is what you notice: the Moon in its ring, this lunation's light as a curve and the signs in their element colours. Pick the theme that suits the hour.
The live Moon, lit for the exact phase angle with earthshine on its dark side, sits in a thin ring with a tick at each quarter. A dot marks where it is in the cycle.
This lunation's illumination as a curve, with New, First Quarter, Full and Last Quarter marked and a line for now.
Illumination, age, distance and degree in sign, each drawn as a small diagram with its exact value underneath.
Signs are coloured by element: fire orange, earth green, air blue, water violet. The chart wheel keeps them, softer.
Tropical or sidereal in one tap from the top bar. The other methods are in Settings, and the tabs sit along the bottom, the active one as a soft pill.
Themes, calculation method, your location and birth details, Data & Privacy, Reference and the newsletter box are all in Settings, so Main ends with Planets Now.
Six tabs along the bottom that you can also swipe between: Main, Chart, Calendar, Vedic, Arabic and Progress.
The live Moon in a thin phase ring, lit for the exact phase angle, with its sign to the arcminute, a moonlight curve, four small diagrams for illumination, age, distance and degree, and moonrise and moonset for the city you pick. On Main, today's note gives the day's reading for the Moon's phase and sign.
The next Full and New Moon in your local time with a countdown, a Supermoon tag when the Full Moon is one, and a list of upcoming supermoons with distance and brightness.
The next six: type, peak time in your time zone, whether the Moon is up where you are, and a Blood Moon label on total eclipses.
Conjunctions, sextiles, squares, trines and oppositions to the Sun, the planets and Chiron, colour-coded, with the orb and a reading. The node methods add the North Node.
The Sun to Pluto plus Chiron by sign and degree, with retrograde flags and a reading when you tap one.
Phase and sign for every day, the exact time of each quarter, and a reading for any day with favoured activities and gardening advice.
The 27 Vedic lunar mansions, always sidereal: pada, lord, deity and gana, when the Moon moves on, and today's tithi. Your birth nakshatra comes with its Mahadasha lord.
The 28 manazil from 0° Aries: Arabic name, star field, tone and span, the current mansion and yours, and when the Moon moves on.
Your Moon's sign and house on a natal-and-transit wheel, the four angles with readings, and your progressed Moon on a ring of the zodiac with the month it enters its next sign.
Every picture in this section is a crop of a real Selene screen, with sample birth data (New York, July 15, 1990, 14:30).
Main opens on the live sky: the Moon lit for its exact phase angle, with earthshine on its dark side, in a thin ring with a tick at each quarter and a dot for where it is in the cycle. Under it come the Moon's sign and degree, with a strip for how far through the sign it is, then this lunation's moonlight curve and four small diagrams for illumination, age, distance and degree.
Main gives moonrise and moonset for your city and counts down to the next Full and New Moon. When the Full Moon is a supermoon it gets a pink Supermoon tag. The Calendar lists the next four with their distance from Earth and how much brighter they look than an average Full Moon, and stars the closest Full Moon of each year. Every Full Moon day in the calendar shows the Moon's distance.
The next six lunar eclipses with type, date, the Moon's sign and how much of it the shadow covers. Open one for the peak time where you are, whether the Moon is above your horizon, and a reading. The list opens by itself when an eclipse is less than 30 days away.
Aspects are colour-coded as in the app: green for sextiles and trines, rose for squares and oppositions, gold for conjunctions. Each shows its orb and a bar for how exact it is, and opens a reading. Below them, Planets Now lists every body by sign and degree, and the sign tracker counts down to the Moon's next sign.
Every day shows its phase as a drawn Moon and the Moon's sign in its element colour, and each quarter falls on its exact day with the time. Tap a day for illumination, distance, moonrise and moonset, then a reading of the Moon in that sign and phase with favoured and less favourable activities and gardening and planting advice.
The Vedic tab follows the 27 nakshatras in the sidereal zodiac with the Lahiri ayanamsa, whatever method you use elsewhere. The Arabic tab follows the 28 tropical manazil from 0° Aries. Both show when the Moon moves on, the mansion you were born under, and a reading. The Vedic tab adds the tithi, the lunar day.
Enter your birth date, time and city once. The Chart tab draws your birth Moon and tonight's sky on one wheel, labelled NATAL and NOW, with the Ascendant, Midheaven, Descendant and Imum Coeli and a reading for each; tap the wheel to zoom in. The Progress tab places your progressed Moon on a ring of the zodiac, a day after birth for each year of life, with your natal Moon's sign in gold, and gives the month it enters its next sign.
Main shows the Moon now. There's no account, no sign-in and no internet connection needed.
Optional: the first launch asks, and you can skip it. Date, time and city from an offline list of 6,485 cities fill in the Chart and Progress tabs, your birth nakshatra and mansion, and the Moon's house on Main.
Tap Tropical or Sidereal in the top bar; Settings has the rest of the methods and three themes:

Yes. Every calculation runs on your phone, including moonrise and moonset, which use a city you pick from the app's own list instead of GPS. Only the optional newsletter signup uses the internet.
No. Without them you still get the Moon now, the calendar, eclipses, supermoons and the current nakshatra and mansion; pick a city for moonrise and moonset. Your birth date, time and city add the Chart and Progress tabs, your birth nakshatra and mansion, and the Moon's house in your chart. The birth time is optional.
Tropical by default. The switch in the top bar flips between tropical and sidereal with the Lahiri ayanamsa, and Settings has draconic, heliocentric and the true or mean node. The Vedic tab is always sidereal and the Arabic tab always tropical, as their traditions are.
Yes. Settings has three themes: Selene, a deep midnight and the default; Graphite, a neutral dark; and Light, pearl and lavender for daytime.
Very. Every phase, position and eclipse time is checked against independent astronomical references, so the numbers you see are ones you can trust.
A Full Moon at least 90% of the way from apogee to perigee, the definition Fred Espenak tabulates. Selene shows its distance from Earth and how much brighter it looks than an average Full Moon.
No. Your birth details, location and settings stay on your phone, and there are no accounts, ads or analytics. If you join the newsletter, your email goes to LD Coda's newsletter service. The privacy policy has the details.
