BIRTHBIT
Your personal horoscope app

Your horoscope,
computed for you.

Every Libra gets the same horoscope. You are not every Libra. Birthbit reads the sky at your exact birth — the date, the time, the place — and builds a daily horoscope that belongs to nobody else. Shift the birth time by two hours and your rising sign changes, your houses rotate, the whole chart moves. That is why no two Birthbit profiles are alike, and why a sun-sign blurb was never going to tell you much.

"The stars incline, you decide…"

Track record

Does your horoscope actually come true?

Every morning Birthbit puts a number on your day — before the day happens. Every evening you say whether it held and log your mood. After two weeks it correlates the two and tells you the answer, including when there is nothing to find and the model does not fit you. No other horoscope can do this: it never makes a claim specific enough to be wrong.

  • An evening check-in that takes five seconds
  • Your mood drawn over your own biorhythm curves
  • The correlation, honestly reported — even when it is zero

How gifted are you? Find your rank.

All eighteen systems keep describing the same person in different dialects. Birthbit tallies their votes into one build: the three qualities you were dealt maxed out, the three the stars left for you to level up — and a single giftedness score that places you on a ten-rank ladder.

  • Core traits: your powered-up three, plus a growth zone with training tips
  • A build rating out of 100 that places you on a ten-rank ladder — the higher, the rarer
  • See the exact stars, numbers and elements that fed your score
  • Share your rank or your build as a pixel card

Your Codex — every tradition, one story

The Codex weaves all eighteen systems into a single portrait of who you are: your element and life path, your nakshatra and decan, your Ba Zi balance, the Mayan sign you'd be greeted by and the arcana at your core — with the one theme that repeats across every culture.

  • Character stats — STR / INT / CHA / LUK gauges from your chart
  • Tap any system for "what does this mean?" and "where does it come from?"
  • Full natal wheel with planets and aspect geometry

Your three numbers — and the one you were never dealt

Every tradition here ends in a number: a life path, an arcanum, a Tzolk'in tone, a Human Design gate. Most of them have nothing to do with each other — but a few keep coming back, and those are yours. The catch is that a repeat is not automatically meaningful: a value on a 1–9 scale collides by accident far more often than one on a 1–64 scale. Birthbit weights every match by how unlikely it was, then measures it against how often that number turns up for everybody else. Without that correction, three and seven would come out "special" for four people in ten — which tells you about arithmetic, not about you.

  • Each number with the systems that produced it — the evidence, not just the meaning
  • How rare your combination is, calibrated over 12,000 birth dates from 1930 to 2030
  • Your shadow number: the digit that appears nowhere in your chart at all
  • Days whose date lands on one of your numbers get flagged in the forecast

FAQ

Good questions

Is Birthbit free?

Yes. Your daily horoscope, the three biorhythm cycles, your sun, moon and rising signs, the moon calendar, your build rating and the evening check-in are free forever, with no ads. PRO unlocks the weekly forecast, compatibility, the full natal chart and the complete Codex.

How is this different from every other horoscope app?

Most apps serve one text per star sign, so six hundred million Libras read the same paragraph. Birthbit computes from your exact birth date, time and place: shift the birth time by two hours and your rising sign changes, your houses rotate and the whole chart moves. It also keeps score of its own forecasts and tells you when they do not fit you.

Do I need my exact birth time?

It helps — your rising sign and the house-based readings need it. Without a time everything else still works, and you can add it later from your profile. Birthbit says when a reading needs a time it does not have instead of guessing.

Does it work offline?

Yes. Planet positions, aspects, lunar phases and biorhythms are computed on your phone from an ephemeris built into the app. As a guest nothing ever leaves your device; an account is optional and only syncs your profile across phones.

Is any of this scientifically accurate?

The astronomy is: planet longitudes, aspects and lunar phases are computed with real algorithms accurate to about a tenth of a degree. The interpretations — what a Gemini or a waxing moon "means" — come from cultural traditions and are meant for entertainment and self-reflection, not as medical, financial, legal or psychological advice.

How is my build rating calculated?

Your score adds up what your chart was dealt across every system: sun and moon stats, master numbers in numerology, allied elements between your Sun and Moon, the ruler of your Egyptian decan, the balance of the five Ba Zi elements, auspicious lunar mansions, high Tzolk'in tones and radiant arcana. Nothing is random and nothing is a personality quiz — every point traces back to your birth date. Ten ranks wait on the ladder, and the air gets thinner toward the top. Where you land is your chart's own doing: open the app and find out. Curious how deep the computation goes? Read the full method.

What do you do with my birth data?

As a guest, nothing leaves your device — name, birth details, partner's date and check-ins all stay local. If you sign in to sync across devices, that same data is stored in our secure backend so you can reach it from any phone. We never sell it, show ads, or run trackers. Full details are in the Privacy Policy.

How do I cancel PRO?

Manage or cancel anytime from your Google Play subscription settings — the app also links you there. Your PRO features stay active until the end of the period you already paid for.

Which platforms are supported?

Android, free on Google Play, including a home-screen biorhythm widget. An iPhone version is not available yet.
