AskSoma vs TimePassages

The astrology app landscape in 2026 spans everything from social-media-style daily horoscopes to professional-grade chart software. AskSoma and TimePassages sit at opposite ends of a fascinating spectrum: one is an AI-native Vedic astrology platform built for real-time conversation, the other is a lovingly crafted Western astrology application built on decades of hand-written interpretive text. People often compare the two because both promise deep, meaningful chart readings — but they deliver that depth in fundamentally different ways, using entirely different astrological traditions.

TimePassages was created by astrologer and author Henry Seltzer and has earned a devoted following for its eloquent, literary-quality chart interpretations rooted in Western tropical astrology. The app is available on iOS, Android, macOS, and Windows, with the full-featured version priced at roughly $10 as a one-time purchase. TimePassages holds a strong 4.6-star rating on the App Store, a testament to its polished writing and reliable chart calculations. However, it operates as a static reference tool: you receive pre-written paragraphs about your placements, but you cannot ask follow-up questions, explore specific life decisions on demand, or get voice guidance. There is no AI, no interactivity, and no Vedic option at all.

AskSoma approaches astrology from a completely different angle. Built on Vedic Jyotish tradition and powered by Swiss Ephemeris for arc-second planetary precision, AskSoma pairs rigorous calculations with an AI astrologer named Soma who can chat and speak with you about any aspect of your birth chart. Whether you need career timing advice during a specific Mahadasha, relationship compatibility through Vedic synastry, or health insights indicated by your sixth house lord, Soma delivers conversational, personalized guidance in nine languages — twenty-four hours a day. In this comparison, we examine accuracy, consultation experience, pricing, and unique features so you can decide which platform fits your astrological needs.

AskSoma uses the Swiss Ephemeris library, the same calculation engine trusted by professional observatories and leading astrology software worldwide. It delivers planetary positions accurate to fractions of an arc-second, which is critical for Vedic astrology where even small shifts in a planet's longitude can change nakshatra boundaries, dasha start dates, and divisional chart placements. Every calculation runs entirely on your device via client-side processing, meaning your sensitive birth data never leaves your phone or computer and is never transmitted to a remote server.

TimePassages also produces accurate chart calculations for Western tropical astrology. Henry Seltzer's team has been refining their calculation engine over many years, and users consistently report reliable planetary positions and aspect orbs. However, TimePassages does not use the sidereal zodiac at all, so it cannot produce Vedic charts, Lahiri ayanamsa calculations, or any of the divisional charts (D-9 Navamsa, D-10 Dashamsa, etc.) that form the backbone of Jyotish practice. For Western astrology enthusiasts, TimePassages calculations are solid and trustworthy; for anyone seeking Vedic precision and Jyotish-specific tools, it simply does not offer that capability.

AskSoma's defining feature is Soma, an AI astrologer that combines Swiss Ephemeris chart calculations with deep knowledge of Vedic Jyotish tradition. You can chat with Soma via text or speak through real-time voice consultations in any of nine supported languages, asking about specific life areas such as career timing during your current Mahadasha, relationship compatibility through Vedic synastry, or health patterns indicated by the sixth house and its lord. Soma maintains full context throughout the conversation, so follow-up questions build on previous answers rather than restarting from zero. The result feels like consulting a knowledgeable Jyotish practitioner who is available twenty-four hours a day, seven days a week.

TimePassages takes the opposite approach: there is no AI layer and no interactivity whatsoever. Instead, the app presents beautifully written paragraphs authored by Henry Seltzer that describe each placement in your natal chart, each current transit passing through your chart, and each progressed aspect. These interpretations are widely praised for their literary quality and psychological depth within the Western tradition. However, the text is identical for every user who shares a given placement — there is no personalization based on the full context of your chart, no ability to ask what a particular transit means for your specific career situation, and no way to follow up on a relationship question or explore remedial measures.

The practical difference is enormous for users who have specific, personal questions. TimePassages will tell you what Sun in Scorpio means in general Western terms; AskSoma will tell you how your specific Scorpio ascendant with Jupiter in the tenth house is shaping your career this quarter during Saturn's Antardasha, and what Vedic mantras and timing strategies might help you navigate the challenges ahead. One platform serves as a library; the other serves as a live consultation.

AskSoma offers a generous free tier that includes a free Kundli (Vedic birth chart) and a limited number of AI questions to explore the platform. The Pro plan costs $7.99 per month (approximately 650 rupees in India) and unlocks unlimited AI consultations via both chat and voice, full access to all thirty-plus life areas, Cosmic Contacts compatibility analysis, birth time rectification, and priority response times. There are no per-question charges, no per-minute billing, and no hidden upsells for premium features — the flat monthly fee covers every capability the platform offers.

TimePassages follows a traditional software pricing model that many users find appealing for its simplicity. The basic mobile app is free and includes limited chart information. The full-featured desktop application costs roughly $10 as a one-time purchase, unlocking comprehensive natal, transit, and progressed chart interpretations along with the transit notification system. This makes TimePassages one of the most affordable full-featured Western astrology apps on the market, and the one-time cost model appeals to users who dislike recurring subscriptions. However, the one-time cost reflects a one-time, fixed experience: you receive a set of pre-written interpretations with no ongoing AI consultations, no voice chat, and no way to ask personalized questions about specific life situations as they arise.

AskSoma's feature set is built around interactive, personalized Vedic guidance. The birth time calculator helps users who are unsure of their exact birth time by analyzing life events and planetary patterns to estimate the most likely ascendant and chart configuration. Cosmic Contacts enables Vedic synastry comparisons to evaluate relationship compatibility based on Nakshatra matching (Ashtakoot Milan), planetary friendships, and house overlays. Voice consultations let you speak naturally to Soma and receive spoken responses, which is particularly valuable for users who prefer conversation over typing, who want guidance while commuting, or who speak one of the nine supported languages more comfortably than they type it. Dasha analysis provides detailed period-by-period Vedic timing predictions covering career, health, relationships, and spiritual growth. Numerology analysis adds another dimension of insight beyond traditional Jyotish.

TimePassages brings its own genuine strengths to the table. The interpretive writing authored by Henry Seltzer is considered among the finest in consumer astrology software — psychologically nuanced, poetically crafted, and genuinely insightful within the Western framework. The transit notification system alerts you to upcoming astrological events affecting your chart, which is a thoughtful feature for staying aware of significant transits without having to manually check an ephemeris. The desktop version supports multiple chart formats including natal, transit, progressed, and composite charts, and allows you to save profiles for friends and family members, making it a useful reference library for Western astrology students and enthusiasts.

Where AskSoma excels is breadth, interactivity, and Vedic depth: more than thirty life areas, real-time AI conversations with unlimited follow-ups, voice consultations in nine languages, and a full suite of Vedic tools from nakshatras and yogas to divisional charts and remedial recommendations. Where TimePassages excels is the sheer literary quality of its Western interpretive writing and its consumer-friendly one-time purchase price. The two platforms serve genuinely different audiences with minimal overlap in their core offerings.
