Most astrology apps tell you what you want to hear. BluntChart was built to tell you what you need to hear. The founders noticed that the most popular apps had completely abandoned their original voice, either becoming subscription-locked cash grabs or retreating into vague, inoffensive wellness content. Meanwhile, the internet was full of people asking "why does my birth chart actually say about me?" and getting nothing useful back. BluntChart uses real astronomical data (Swiss Ephemeris) combined with advanced AI to deliver readings with actual personality, specific, direct, and genuinely insightful. One reading, one payment, zero fluff.
Next.js for the frontend framework. Swiss Ephemeris as the open-source astronomical engine for accurate birth chart calculation (the gold standard used by professional astrologers). Advanced AI for generating the personalized reading. Supabase as the database for user data and reading storage. Lemon Squeezy for payment processing. Resend for email delivery of readings. Vercel for hosting and deployment. Puppeteer/Canvas for generating the shareable result card image.
BluntChart is the only astrology app that delivers brutally honest, AI-generated birth chart readings — no wellness-speak, no vague affirmations, no sugar-coating. Built on Swiss Ephemeris (the same astronomical calculation engine used by professional astrologers), it generates hyper-personalized readings via advanced AI that read like a brilliant friend who actually tells you the truth about yourself. Unlike every competitor, it's pay-per-reading ($12 one-time) rather than a monthly subscription trap, and every reading comes with a beautifully designed shareable result card built for virality on TikTok and Instagram.
Every major astrology app in 2025 has one or more of the following problems: Co-Star moved to $9/month and locked basic features behind a paywall, triggering a mass user exodus. The Pattern is soft and personality-light. Nebula and Sanctuary charge $10–$30/month for inconsistent quality. Chani and VAMA are pure wellness-speak with zero edge.
BluntChart solves all of it in one product: one-time payment, real chart calculations, sharp and honest tone, and a shareable output that markets itself. Users have explicitly called the $9/month price point on Co-Star "insane" for an AI astrology service, and that's exactly the gap BluntChart fills — premium depth at an impulse-buy price, with no recurring commitment.
Women aged 18–35 in the US, UK, and Australia — primarily Gen Z and Millennials. Over 59% of astrology app users globally fall in the millennial and Gen Z categories, and around 52% of US astrology app users rely on astrology for decisions related to relationships, career, and personal wellness. This audience is already spending money on astrology, already active on TikTok and Instagram, and already frustrated with existing apps. They want something that's smart, honest, and shareable — not another subscription and not another "the universe supports you" platitude.
It described my birth chart very clearly... It was very interesting to read. I had fun! It had all the real natal chart, readings, and my flex card (really surprised by that - I loved it!). It explained the placements of the stars and their meaning very subtly. Overall, a good experience.
