AstrolithRead the sky like a calendar.
Your birth chart, the daily sky, and the reason under every sentence. It doesn’t tell your future; it shows its work.
The sky when you were born.
Sun, Moon and Ascendant; 14 placements and every aspect. The math runs offline on your phone.
The day’s tone at a glance.
Easy, Mixed or Needs care, compared with your usual days. With what to do and what to avoid.
Every sentence opens to its reason.
The plain explanation comes first; or go on to the technical details: the aspect’s name and orb, the exact time and the house. No sentence comes without a reason.
Retrograde, to the minute.
Retrogrades and eclipses, new and full Moons, void-of-course Moon times. Periods specific to your chart, alongside the daily intensity.
The sky calendar
Not what will happen. When it happens.
The times are calculated on your device; the site and the app use the same code.
We did not make up where the planets are.
We compared planet positions with NASA JPL Horizons data at 600 points between 1879 and 2050. The largest difference was less than 1/200 of a degree.
Matches a professional reference.
House cusps match in six house systems. Adjust your birth time as often as you like; if it is unknown, the app says so.
Read the method
Compatibility, by code.
Send your match code to a friend, and they can send theirs back. No server: the code carries only birth details and travels only through the app you choose.
“You two today.”
A daily look at your day together. Every friend added with a code is free; the relationship chart and unlimited compatibility come with Astrolith+.
Every reading has a “Why this?” underneath.
In the app the same reason sits under every sentence, calculated for your own birth chart. The example below was calculated on this page, for right now.
Few words, a lot of math.
The claims here are the ones in the store listing; nothing was added.
