What is inside
Everything follows from your chart.
Tell it when and where you were born. The rest is built on that, not on a sun-sign column written for a twelfth of the planet.
A reading written for you
Seven sections: an overview, your Sun, Moon and rising sign, your personal planets, your aspects and your elements. Written by AI from your own chart, not picked from a shelf.
Today, every day
A daily horoscope for your sign, with an affirmation, a lucky colour and number, and a short strip on what the sky is doing: Moon sign, phase and which planets are retrograde. Set a daily reminder for the time that suits you.
Listen instead
Have your horoscope and your reading read aloud, at the speed and in the voice you choose. Personal readings are spoken on your phone and never sent anywhere for voice.
Moon calendar
Every day of the month with its phase and Moon sign, and the exact time of each new, quarter and full moon. Drawn the right way round for your half of the world.
Sun calendar
When the Sun enters each sign this year, the equinoxes and solstices named for your hemisphere, and the day of your solar return.
The four elements
Fire, earth, air and water: where your Sun and Moon sit, what today's Moon adds, and a small self-care suggestion for each.
Love & friendship
Which signs sit easily with yours, which pull against it, and a quick check against anyone you like. For fun and reflection, and it says so.
Daily notes
A few lines a day, tagged with the Moon, with a prompt that follows the phase. Type or dictate. Look back and see how your moods track the sky.

- Moon
- Fire
- Earth
- Air
- Water
- Flowing aspect
Calculated, not guessed
The astronomy is done properly.
A chart is only worth reading if the positions are right. Most of the work in Luna & Sol is in getting them right.
- Positions to about an arcminutePlanet longitudes come from an astronomical engine, with true obliquity and the equinox of date.
- Four house systemsPlacidus, Whole Sign, Equal and Porphyry. Near the poles, where Placidus stops working, it switches to Porphyry and tells you.
- The right hour, even in 1942Birth times are converted using historical timezone rules, including wartime double summer time. If your hour happened twice, or never happened, it asks.
- Your hemisphere's MoonA waxing Moon is lit on the left in Brisbane and on the right in London. The app draws the one you see.
23 languages
Read it in your own.
Signs, phases, the daily reading, both calendars, elements, love & friendship and notes are translated in every one of these, and Arabic runs right to left as it should. The chart screens, settings and parts of the terms are still in English while translation catches up.
Free & Premium
Most of it is free.
Your chart, the calendars, elements, love & friendship and notes cost nothing. Premium adds your personal daily horoscope, the rest of your reading, a week ahead and more birth profiles. Prices will be shown in your own currency in the app.

Your details
A birth date is personal. It is treated that way.
No account needed
You can use the whole app without signing in or giving an email address.
A city, not a location
You pick your birthplace from a list. The app never asks your phone where you are.
Not sold, not tracked
Your details are not sold or shared with advertisers, and no birth data goes to analytics.
Yours to take or delete
Export everything as a file, or delete your account and all its data, from inside the app.
This is a summary of how the app works. The full privacy policy will be published here before launch.
Questions
Good to know.
Do I need to know my birth time?
No. Without it you still get your Sun, Moon and planets and the aspects between them. The birth time adds your rising sign and houses, and settles your Moon sign on days when the Moon changed sign.
Who writes the readings?
Your natal reading and the horoscopes are written by Claude, an AI made by Anthropic, from your calculated chart and the day's sky. The AI writes the words; it never works out the positions. When no AI horoscope is available, the app shows a simpler daily reading built from the day's Moon. The app says all this inside as well.
Does it work without a connection?
Your chart, your reading and recent horoscopes are kept on your phone, and there is always a daily reading in your language even with no signal. Setting up your chart and writing a new reading need a connection.
Is astrology meant to be taken as fact?
No. Readings are for reflection and enjoyment. They are not medical, mental health, financial, legal or relationship advice, and they are written to avoid predicting illness, death or money.
When is it out?
It is in development for iPhone and Android. There is no release date yet.
