Most apps reduce you to a sun sign and a fortune-cookie horoscope. StarBind computes your full natal chart with Swiss Ephemeris — the same engine working astrologers use — then writes a reading drawn from your sky, not a template.
Launching on iOS and Android. Email hello@starbind.me to be notified when we go live.
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 natal chart — transits to your real placements, by exact degree.
Streaks, push spam, daily anxiety loops.
Notifications only when the sky is doing something real to your chart.
Rounded planets, hidden house systems.
Swiss Ephemeris, every aspect to its orb, five house systems one tap away.
Your data trained on, sold off, leaked.
Export it. Hard-delete it. Done.
A subscription wall to see your own chart.
The chart, the Big Three, and daily transits are free. Pay only when you want the AI to write about it.
Real calculations, real interpretation, none of the slot-machine theatrics most astrology apps run on.
Swiss Ephemeris under the hood. The luminaries, the eight planets, Chiron, the lunar nodes (true), and Black Moon Lilith (mean) — with the five Ptolemaic aspects plus quincunx, semisextile, and sesquiquadrate. Retrograde, stationary, and out-of-bounds declination flagged.
Sun, Moon, and Rising rendered as three quiet gold cards — sign, exact degree, house, ruler, with dignity flagged where it earns one. The handful of placements a working astrologer reads first.
Skip the generic Sagittarius read. StarBind pulls today’s transits against your natal chart and writes a reading from the aspects that are actually live in your sky right now.
Pinch the wheel. Tap any planet for its sign, house, dignity, and aspects. Applying aspects glow, separating ones fade. Sixty frames a second, fully interactive — the first chart wheel that doesn’t feel like a PDF.
We don’t ask the model to predict — we ask it to translate. Your full chart, with every degree and orb, becomes several thousand words on personality, love, career, and growth. Every claim maps back to a placement on your wheel.
Save partners, parents, friends. Compare synastry, then opt into push alerts the moment Saturn forms a meaningful aspect to your Moon — never a notification just to refill the engagement bar.
The Ascendant moves a full sign every two hours — a guess wrecks the chart. Tell StarBind a handful of dated life events (a marriage, a move, a loss) and our rectification engine searches thousands of candidate times, narrowing your birth moment to the minute.
No prior astrology knowledge needed. Just a date, a time, and a place.
Date, time, and place. We don’t ask for a name or an email to cast your first chart. Don’t know your birth time? We’ll show planetary positions and honestly disable the houses and ascendant rather than guess them.
Swiss Ephemeris computes ten planets, twelve houses, and every aspect between them in under a second. Cached so you can read it offline — on a plane, on the subway, anywhere.
Big Three cards, planet table, interactive wheel, aspect grid, and a long-form AI reading written from your chart specifically. Every paragraph cites the placement it was drawn from.
Mobile-first by design. Smooth gestures, instant calculations, offline chart caching, and quiet push notifications when the sky has something worth saying.
Save the people who matter — partners, parents, the friend you reread every text from. StarBind reads the cross-aspects between your charts and shows the relationship in six honest dimensions.
Yes. Free to download, with a free plan that always stays free. The chart, your Big Three, and daily transits don’t cost anything. Long-form AI readings use a small in-app currency called stardust.
Swiss Ephemeris — the same arc-second-accurate algorithms working astrologers and astronomy software use, derived from JPL ephemerides.
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.
Yes — iOS 15+ and Android 10+, with feature parity across both platforms.
StarBind exposes the actual chart data — exact degrees, aspects, dignities, house systems — and pairs it with AI readings you can fact-check against your own wheel, instead of opaque one-liners.
Placidus by default, with Whole Sign, Equal, Koch, and Porphyry one tap away. Tropical zodiac for Western readings; sidereal modes available.
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.
Yes. Birth details are encrypted in transit, never sold, and you can export or permanently delete your account at any time under GDPR.
Free forever plan. No account needed to cast your first chart. No subscription required. No nonsense — and we mean that.
