Mobiwise

What Mobiwise does

Mobiwise (모비와이즈) is a South Korean sole proprietorship operated by representative Choi Yun-gi, running two free web-based divination platforms under the sajumyeongri (사주명리) brand. The flagship product, 사공만세력 (Sagong Manse ryeok), is a Four Pillars of Destiny (사주) calculation platform launched March 3, 2026 that computes natal charts using Korean Astronomy Research Institute solar-term data, regional longitude corrections, daily astronomical equation of time adjustments, and true solar time (진태양시). It supports three competing classical theories (음양순역설, 동생동사론, 수토동궁법) for the Twelve Life Stars, three month-command tables (명리추명학, 자평진전평주, 삼명통회), and configurable lunar/solar input, daylight-saving corrections, and 야자시/조자시 handling. A second product, 사공타로 (Sagong Tarot), launched April 17, 2026, provides free tarot readings on the Universal Waite deck with five spread types and integrated learning content.

The technology stack is rule-based: astronomical data tables drive the calculation core, and an AI chatbot (사주 고전 챗봇) is layered on top for Q&A against classical texts. The platform is hosted on Google Firebase/Cloud Run/Firestore, with Google, Kakao, and Naver OAuth for sign-in and Apple SSO planned. All features are free; the stated revenue model is advertising only, with no subscription tiers, paid plans, or B2B offerings disclosed. Primary users are Korean saju astrology learners and professional practitioners, with secondary segments in tarot users and general curious consumers. Marketing runs through the operator's sajustudy.com blog and organic search; no paid acquisition, sales team, or app-store presence exists today.

Core offering

Mobiwise operates two free, web-based Korean-language divination platforms. 사공만세력 (Sagong Manse ryeok) is a Four Pillars of Destiny (사주명리) calculator that computes natal charts using Korean Astronomy Research Institute solar term data, regional longitude corrections, true solar time adjustments, and historical summertime handling, with multi-theory comparison features. 사공타로 (Sagong Tarot) is a tarot reading platform using the Universal Waite deck with multiple spread types. Both services are free, self-serve, and targeted at Korean astrology learners, practitioners, and the general public.

Product overview

Mobiwise operates two complementary Korean-language fortune-telling and divination platforms under the 사공명리 (Sagong Myeongri) brand. 사공만세력 is a free Four Pillars of Destiny (사주명리) calculator that computes natal charts using astronomical data with regional adjustments, offering analysis of fortunes, life stars, and palace theory. 사공타로 is a free tarot reading service using the Universal Waite deck, providing multiple spread types and learning content. Neither product uses AI/ML technologies; both are rule-based calculation and interpretation platforms.

Direct peers

• Jeombonanamja (점보는남자): Korean tarot reading service operated by Park Jun-hyung, providing structured tarot interpretations via mobile app and digital content. Direct peer in the Korean tarot/fortune-telling market, competing for the same general public interested in divination services.
• The-SaJu (더사주): Korean Saju and traditional astrology analysis service targeting learners and practitioners. Offers comparable free Saju chart interpretation features and theory-based content serving the same Korean-speaking fortune-telling enthusiast segment.
• Sajudotcom (사주닷컴): Korean-language Saju information portal providing natal chart calculation, classical theory explanations, and learning resources. Direct competitor targeting the same Korean astrology learner audience with overlapping free content and Saju interpretation features.

Broad incumbents

• Co-Star: International astrology app offering personalized birth chart analysis, daily horoscopes, and AI-driven compatibility features. Operates in the broader Western astrology market but shares the birth-chart-as-a-service category and product-led growth model that Mobiwise employs for its Korean Saju calculator.
• Sanctuary World (Sanctuary): Astrology and tarot platform offering live psychics, daily horoscopes, and birth chart readings with a freemium model. Comparable to Mobiwise in combining multiple divination services (Saju + tarot) with content-driven user engagement, though operating primarily in English-speaking markets.
