What it is
LUNA Studio is a chart browser and discovery app built around a public figure library, run by the Luna Astrology team out of the United States. The web product at lunaastrology.com launched around 2019 and the iOS app followed in 2022. LUNA is best known for 2 things: a curated celebrity chart database with roughly 30,000 public figures, and a birthday-matching social mechanic that pairs users with strangers born on the same day. The site itself pulls roughly 11,600 organic visits a month, mostly to long-tail celebrity chart pages such as "rosalia birth chart", "ted bundy birth chart", and the cluster of historical-figure charts that rank for zero-difficulty long-tail terms. The product is polished, the typography is good, and the chart calculation is reliable Swiss Ephemeris.
Who uses it
LUNA's audience is the curious consumer in their twenties or thirties who is starting to read charts and wants a slick mobile-first experience. The typical session is 5 to 10 minutes of browsing celebrities, comparing a friend's chart, and reading the daily transit feed. Working astrologers with paying clients are not LUNA's audience, and the product does not pretend to be. There is no roster, no notes, no intake, no Stripe invoicing. House system is locked to Whole Sign with no choice. The product is built for discovery, not for paid practice.

Where Astrolium does it differently
LUNA and Astrolium do not directly compete. They are different products built for different audiences. LUNA is a polished discovery surface for consumers; Astrolium is a workspace for paid client practice. The Venn overlap is small enough that the team usually recommends LUNA to friends who are not running a paid practice.
Where Astrolium does it differently is the practitioner side. Astrolium ships a CRM with intake forms and per-client session notes, multiple charts per client (natal plus relocated plus solar return plus progressed, all linked), 23 house systems instead of just Whole Sign, the full Hellenistic time-lord stack (profections, Zodiacal Releasing for Spirit and Fortune, Firdaria), and the live predictive scrubber. None of those make sense in a consumer iOS app, and LUNA's team has been clear that they are building for discovery, not for client work.
For practitioners who use LUNA for celebrity research and want a smaller curated public-figure library, Astrolium ships roughly 1,200 charts prioritized by Rodden Rating AA and A. That smaller set is useful when accuracy matters more than breadth.
If you are moving from LUNA
The full side-by-side (celebrity library depth, house system, predictive surface) lives at LUNA vs Astrolium. For Astrolium's pricing and the features hub, the links land on the working pages. LUNA does not export .SFCHT or .AG chart files, but it does let you share birth data; 10 to 50 charts migrate in under 5 minutes via CSV.
