Why astrologers switch

Everything the craft demands, nothing it doesn't

Five engines under one roof — precision, timing, presentation, interpretation and language — each built to a standard you can stake a consultation on.

01 · The calculation core

Configure the astronomy behind every chart

AstroWatch exposes the whole engine, not a locked preset. Choose your frame of reference, your house division and your node model — then trust the numbers, because they come straight from Swiss Ephemeris.

  • Tropical & Sidereal zodiacs with 8 ayanamsas — Lahiri, Fagan/Bradley, KP, Raman and more; Draconic coming soon.
  • 28 house systems — Placidus, Koch, Whole Sign, Regiomontanus, Campanus, Gauquelin… with automatic high-latitude fallback beyond ±66°.
  • True & mean nodes, three Lilith models, geocentric or topocentric parallax, and true- vs mean-solar-day progressions.

02 · The timing engine

See exactly when a contact perfects

The Aspect Calendar plots every contact across a span of time as smooth orb-curves — colour intensity reads as closeness — then hands you the exact hits in a sortable grid. Transit-to-transit, transit-to-natal, or natal-to-progressed.

  • Aspect Finder graphs & exact-hit grids over 30 days to a full year, exportable to CSV or your timeline.
  • Temporal Timeline — scrub the working chart by any unit from seconds to years and watch the sky move.
  • Movements of the Moon — lunar aspects, lunar days, void-of-course, eclipses and the 28 Arabic mansions.

03 · The presentation

Charts and reports worth handing to a client

Twenty-one hand-tuned wheel themes across Dark and Light modes — from obsidian midnight to a medieval parchment codex — restyle the wheel without touching the data. Layer natal, transit and return rings, then export a print-ready figure.

  • Bi-wheel, tri-wheel & quad-wheel overlays with a full cross-layer aspect grid.
  • Synastry & relationship comparison, solar returns, and secondary progressions side by side.
  • Print-ready reports in Classic or Parchment styles — A4 or Letter, straight to PDF.

04 · The interpretation engine

Charts that read themselves

A smart interpretation engine turns the chart into prose — composing a chaptered, book-length natal report of 70+ pages in warm, human language, organised by the areas of life rather than raw astrology.

  • 70+ page written natal reports — grouped into life-area chapters with a cover, table of contents and page-referenced sections.
  • Plain-language headings — "Venus in Aquarius" reads as "Freedom in Love", with the astrological term kept alongside for reference.
  • Gifts, challenges & growth callouts throughout — exported print-ready to PDF in Classic or Celestial styles.

05 · Your language

Work — and report — in your clients' language

The whole interface switches language in one click — menus, dialogs, dates and the Vedic suite included. And because every interpretation is authored in the Interpretation Workbench, your written reports can go out in the language each client actually reads.

  • Four interface languages — English, Deutsch, Türkçe and हिन्दी, switched instantly from Settings → Language.
  • Multi-language PDF reports — choose English, Urdu, Hindi, German or Turkish in the Report Manager; chapter titles, headings and labels follow.
  • Translate in the Workbench — add your own translation beside every original text and report term; right-to-left Urdu and Devanagari typeset correctly in print.

Questions

Good to know

Every chart is computed with the Swiss Ephemeris (SE 2.10), the same DE431-derived engine trusted across professional astrology software. Positions are accurate to the arcsecond across the supported date range.

Your Extended or Pro licence is for you, not a single machine — it follows your Microsoft account, so you can use it on the Windows devices you personally use. macOS, iOS and Android editions are on the way; each platform's edition is licensed separately, and a future update will let you sync your charts between platforms. AstroWatch is local-first, so your charts live on your device rather than on our servers.

Yes. Switch to the Sidereal zodiac and choose from eight ayanamsas including Lahiri, KP (Krishnamurti), Fagan/Bradley, Raman and a custom value. Whole Sign houses, true nodes and topocentric positions are all first-class.

Pro exports print-ready natal figures in two styles — a clean Classic layout and a classical Parchment codex — sized for A4 or Letter and saved straight to PDF. Timing data exports to CSV.

The free tier casts full natal, transit and solar-return charts with a live aspect list, the Sun & Moon dashboard, Placidus and Whole Sign houses on the Tropical zodiac, and three chart themes — no account needed. Pro unlocks the timing engine, all systems, synastry and exports.

Yes. The ephemeris runs locally on your device, so charts calculate with or without a connection.
