Strength: The only Korean Saju app shipping in 9 native languages, with a real free tier (unlimited basic 4 Pillars) and a 24-hour refund on every paid reading. Built on the 1,200-year Saju (사주명리) tradition, with explicit Day Master analysis across the 10 Heavenly Stems and 4-layer Gunghap (couple compatibility). Pricing is the most flexible of the four: Daily ₩1,500, Monthly ₩29,900, or Lifetime ₩287,040.
Weakness: Android-first; an iOS app is still on the roadmap.
Strength: Long-standing player in Korea's domestic Saju market. Strong on traditional Korean fortune-telling depth and a recognisable brand name in Korea. English access expanded in May 2026, broadening its audience beyond Korean speakers.
Weakness: Subscription pricing is not transparently published in English; the free tier is limited and there is no public refund guarantee.
Strength: Readings are curated by a certified Korean Myeongri master with 15+ years of experience and delivered as polished, long-form English reports. The Love Reading at $19 is a clear, one-shot purchase — no subscription trap. Ideal for readers who want a human, not an algorithm.
Weakness: No persistent free tier (only a free mini-reading), English only, and the master-curated workflow means slower turnaround than an app-style experience.
Strength: The cultural reference point for Western astrology on iOS — witty, social, and famous for its sharp daily push notifications drawn from NASA ephemeris data. A great fit if you already think in terms of Sun / Moon / Rising rather than Heavenly Stems and Earthly Branches.
Weakness: Not Korean Saju. The 4 Pillars system, Day Master analysis, and Gunghap aren't part of Co-Star's model, and the app is iOS-only.
You want the full Korean Saju tradition (Day Master + 4-layer Gunghap) in your own language, with a real free tier and a refund if it doesn't land. Especially if you're outside Korea and want PayPal / global cards instead of Korean-only checkout.
You're a Korean speaker who values a familiar domestic brand and you're comfortable with a subscription. Best fit when you live in Korea and don't need broader language support.
You specifically want a long-form, English, master-curated Korean Saju report and price isn't the deciding factor. A one-shot $19 Love Reading is the cleanest entry point.
You want Western astrology (Sun / Moon / Rising) on iOS with a witty, social tone — not the Korean 4 Pillars system. Different tradition entirely; pick this only if you've ruled Saju out.
