The problem

Most astrology apps sound deep and say nothing.

The same vague lines for millions of people with the same sign, delivered with total confidence and no reason given. It's fun for a second, but useless for your actual week.

Typical horoscope app

"Expect the unexpected. Trust the universe today."
  • Generic: written for your Sun sign, not for you
  • No reasons: you can't check where it came from
  • Fake certainty: never says "we don't know"
  • Nothing to do with it once you've read it

Orrery

"A good stretch for getting credit. So what: share your best recent result."
  • Computed from your exact birth minute and place
  • Every line cites its classical source
  • Shows how sure it is, and when it isn't
  • Turns into a plan, then tests itself on your life
What you get

Six things no other astrology app does together.

01 · Your day, at a glance

One dial. Seven parts of your life.

Work, love, money, home, friends, growth and energy. Each arc lights up by what's actually active in your chart today, around the Moon's real phase. Tap any arc for the why.

02 · Plain words, with receipts

What it means, what to do, and where it came from.

Every insight leads with plain English and a "so what". Underneath is the exact source (Valens, Lilly, Parashara and more), how solid your chart is on it, and how many traditions agree.
