Real Astronomical Math — Not Vibes

Your chart.
Actually computed.

Real astronomical ephemeris math, on your device. Arc-second accurate, works offline. And if you don't know your birth time, Vela says so instead of guessing.

Real astronomy. Plain language.

Vela computes your chart from real ephemeris data, then explains what it means — clearly, without mystifying what it doesn't know.

1

Enter Your Birth Details

Date, time, and place. If you don't know the time, say so — Vela labels your chart honestly.

2

Chart Computed On-Device

Every placement, cusp, and aspect calculated from real ephemeris data. No internet needed.

3

Your Daily Reading

One reading each morning — built from your actual transits that day and the current moon phase.

4

Ask Your Chart Anything

A chat that can see your actual placements — not just your sun sign. 20 messages a week.

Everything built, nothing invented

Vela only claims what it actually ships. Every feature listed here is in the app.

Full Natal Chart

Sun through Pluto plus both lunar nodes, placed to the arc-second. Ascendant and all twelve houses in Whole Sign, Placidus, or Porphyry — always labelled.

Daily Reading Premium

One reading per morning grounded in the real transits to your real chart plus the current moon phase. One notification, never a second.

Chart Chat Premium

Ask questions and get answers from your actual computed chart. Up to 20 messages a week — the limit is real and stated upfront.

Compatibility Premium

Add someone's birth details and see the real inter-chart aspects between you, plus your composite chart. Every connection listed with its exact orb. Everything stays on your device.

Unknown Birth Time

No birth time? Vela shows a clearly labelled solar chart and explains what's missing — it never defaults to noon and fabricates a rising sign.

Home-Screen Widget

Your daily line and the moon phase, always visible. Free forever — the widget doesn't need a subscription.

We say exactly what we know

Vela's two real differentiators: real on-device ephemeris math, and billing that shows you the full price before you agree to anything.

Real Ephemeris Math

SwiftAA/AA+: a C++ implementation of Meeus, Astronomical Algorithms. The same class of math used for planetarium software — arc-second accurate, computed on your device, works without a connection.

Honest Billing

The paywall shows the real renewal price and the exact date you'd be charged, in full size — never fine print. A reminder fires two days before the trial ends. Cancelling is one visible tap.

Your Data Stays On-Device

No account, no sign-up, no cloud sync. Your birth details never leave your phone except inside a reading you asked for.

Entertainment, Not Prediction

The astronomy is real. The interpretation is written for reflection and entertainment — not prediction, and not professional advice. Stated plainly in the app and here.

Real price, up front.

$49.99/year, renews 7 days after you start the trial unless cancelled — shown in full before you agree to anything.

Common questions

What if I don't know my birth time?
Vela shows you a clearly labelled solar chart and explains what's missing — it never defaults to noon and invents a rising sign that's wrong ~92% of the time. If you know roughly when you were born, Vela can help narrow it down.
How accurate is the chart math?
Every placement is computed on-device from real astronomical ephemeris data using SwiftAA/AA+, an implementation of Meeus, Astronomical Algorithms — the same class of math used for planetarium software. Arc-second accurate, no internet connection needed.
Does Vela use Swiss Ephemeris?
No. Vela uses SwiftAA/AA+, a C++ implementation of Meeus. The claim is "real astronomical ephemeris math" — we don't claim Swiss Ephemeris because we don't use it.
What house systems does Vela support?
Whole Sign (the default), Placidus, and Porphyry. The zodiac and house system are always labelled on the chart so you always know exactly what you're reading.
Is my data private?
Yes. There's no account, no sign-up, and no cloud sync. Your birth details never leave your phone except inside a reading you asked for. All data is stored locally on your device.
What's included free vs premium?
Free includes your Big Three reveal, the home-screen widget with your daily line and the moon phase, and a daily notification. Premium unlocks your full natal chart, the complete daily reading, chat (up to 20 messages/week), and compatibility with synastry and composite charts.

Your chart, computed.
Your billing, honest.

Real astronomical math. No accounts. No guessed rising signs. No surprise charges.
