Today, written for one person.
Written from the aspects live in your chart today: by exact degree, not your sun sign. And a push only when the sky does something real. No streaks to protect.

Do your charts actually get along?
Save the people you care about and see the real chemistry, romantic, friendship, or karmic, across six honest dimensions. Not one vague score. Opt in to a push when a transit moves the two of you closer.
What makes it different Most astrology apps do this.
Most astrology apps do this.
StarBind doesn’t.
A short list of choices we made, written down so you can hold us to them.
-
A horoscope based on your sun sign.
A reading drawn from your full chart: your sky, not your sign’s.
-
Streaks, push spam, daily anxiety loops.
Notifications only when the sky is doing something real to your chart.
-
A subscription wall to see your own chart.
Your chart, Big Three, and daily transits are free. Everything else is optional: more readings in the app, or one report in writing.
The sky right now
Tonight’s moon.
The Moon, computed locally, just for you. This page checks the sky too.
The full Moon tracker lives in the app: phase, sign, void-of-course hours, and what tonight means against your chart.
The whole sky
Every body. Every aspect. By exact degree.
Most apps round the sky down to a sun sign. StarBind draws all of it, and shows its work.
- Bodies
- Sun through Pluto, plus Chiron, the lunar nodes and Black Moon Lilith: thirteen in all, each placed by sign, house, and exact degree.
- Aspects
- Majors plus quincunx, semisextile and sesquiquadrate: each measured to its orb.
- Flags
- Retrograde, stationary and out-of-bounds: marked rather than hidden.
- Houses
- Placidus, Whole Sign, Koch, Porphyry: one tap apart.
- Zodiac
- Tropical or sidereal: your call, switchable any time.
- Data
- The same planetary data NASA uses: accurate to fractions of an arcsecond.

Pick your school. Or build your own.
The same birth moment, read three ways: each tradition honestly labeled, switchable any time.
Modern Western
Sun at 14° Leo
Identity and vitality: the self you’re growing into, read psychologically.
Vedic ClassicalSurya at 19° Karka
The sidereal zodiac shifts the very sign: same moment, Sun in Cancer.
Hellenistic ClassicalSun in its domicile
A day chart’s sect light, judged by dignity first: the way the ancients read it.
Same moment, three true readings: switch any time. Or open Expert Settings and set the rules yourself: zodiac, houses, orbs, dignities. Every app reads the sky in some tradition; most never say which. StarBind names its rules, and hands you the knobs.
Yours, on your terms
No ads in the app. Never sold.
StarBind holds some of your most personal data: your birth details, your dreams, your questions. We treat that as a responsibility, not an inventory.
- “Data Used to Track You: None”The app’s actual App Store privacy label: no ad SDKs, no cross-app tracking, no data brokers.
- We never read your contacts or photosAnd we never sell your data. Full stop.
- Your data is yoursExport it or permanently delete your account anytime, for real, and for good.
- The website asks before it measuresAnalytics and ad tags run only if you say yes, and you can change your answer in the footer.
That label is the app’s. Don’t take our word for it: open any astrology app’s privacy label, then look at ours.
Common questions
Before you begin.
Is StarBind free?
The app has a free plan: your chart, Big Three, and daily transits are free. Limited app readings are included, with more through optional subscriptions. PDF reports are a separate, one-time purchase.
How accurate are the calculations?
We build on the same JPL planetary data NASA uses. Positions are accurate to fractions of an arcsecond: the gold standard for professional astrology and astronomy software.
Do I need to know my exact birth time?
For your Rising sign and house cusps, yes. Without it, StarBind still produces an accurate Sun and Moon and a usable chart: flagged as time-uncertain, with the houses and ascendant honestly disabled rather than guessed.
Where can I get the app?
Available on Android 10+. iOS is coming soon. Personal PDF reports are available separately on the website.
How is StarBind different from other astrology apps?
StarBind exposes the actual chart data: exact degrees, aspects, dignities, house systems. It pairs that with readings you can fact-check against your own wheel, instead of opaque one-liners.
What house system does StarBind use?
Placidus by default, with Whole Sign, Koch, and Porphyry one tap away. Tropical zodiac for Western readings; sidereal modes available.
Can I check compatibility with friends and partners?
Yes. Save the people you care about and StarBind computes synastry, the aspects between your charts, plus optional alerts when a meaningful transit lands on theirs.
Is my birth data private?
Yes. Birth details are encrypted in transit, never sold, and you can export or permanently delete your account at any time.
