Alma: Natal Chart App
Alma is a natal chart app we design, build and run ourselves. Eight systems read the same birth data, and every paragraph of the reading names the position it was read from.

Who uses Alma
People who want to see how their chart was read: which planet, which house, which degree. Alma describes a person, not what will happen to them.
- Readers curious how astrology, numerology and tarot compare on one birth date.
- Anyone comparing their chart with another person’s: four measures, never one score.
- People who don’t know their birth time: everything that does not need it still works.
Why we built Alma
The brief we set ourselves: every number has to be real, every sentence has to name the position it was read from, and the app must never predict. Where the systems agree, Alma says so; where they contradict each other, it shows that too.
- Real positions from NASA JPL’s DE440s ephemeris.
- No geocoding service learns where a person was born.
- No forecasts and no medical, legal or financial advice.
Eight systems and 41 chapters in one app
Eight systems, one birth date
Natal chart, numerology, tarot birth card, transits, solar return, compatibility, astrocartography and cross-synthesis: 41 chapters in all.
Where they disagree
Cross-synthesis sets three systems side by side on nine areas of life and counts where they agree and where they split.
Every paragraph cites its source
Each paragraph names its placement. Code rejects a paragraph that cites nothing or cites what the chart lacks.
Ask about your chart
Questions in your own words, answered from your chart.
What is free, what is paid
The calculated results are free. Most written chapters are bought in the store.
Private by default
No advertising ID, no third-party analytics. The account can be exported or deleted in Settings.
How a reader uses Alma
Enter birth data
Date, time and place. Without a birth time, everything that does not need one still works.
Open your systems
Each system opens with its calculated results, free.
Read the chapters
Every paragraph shows what it was read from, such as the ascendant at 12° Leo.
Ask Alma
Ask questions about your own chart.
How we build and run Alma
One Flutter codebase ships the iOS and Android apps; the site at alma.pazl.ai is Next.js. A FastAPI backend on PostgreSQL computes the charts, keeps purchases and sends notifications through APNs and FCM.
Real astronomy
Positions from NASA JPL’s DE440s ephemeris, Placidus houses and historical time zones from an offline gazetteer.
Writing with a check
Claude writes the chapters: Opus 5 for paid ones, Sonnet 5 for free ones. A validator checks every paragraph against the chart before it is shown.
Plain store billing
One-time purchases and a monthly subscription. No trial, no introductory price.
Seven languages
Including English, Spanish, German, Italian, French and Brazilian Portuguese.

No. Alma is our own product: we designed it and we build and run it, from the apps and the site to the backend.
