Sothis is a calm daily compass. Astrology, numerology, biorhythms, and the oldest cycle — held quietly in your pocket. For people who like astrology but don't want to be yelled at. WHAT SOTHIS IS A quiet cabinet of celestial instruments — an antique astrolabe with a real Sun at its centre, a 2.5D orrery of the classical wanderers, a numerology hub with a celestial pinball reveal, hand-drawn constellation traces from 1822 star atlases, and four private rhythms that meet you where you are. Each morning, one calm reading. No pushed alerts. No "the universe is angry." No streaks. No ads. No woo. Every part of Sothis is free for fourteen days. FREE FOREVER — YOUR DAILY COMPASS - Today — a calm daily verdict and reading - Your three rhythms — physical, emotional, intellectual - The oldest cycle — private, encrypted on your device, off any time - Breathe — a tuned three-minute grounding practice - Calendar — the week around today - Diary — log your days and watch your own hit rate build No time limit. No asterisk. PREMIUM — THE OBSERVATORY £4.99/month or £39.99/year, after a 14-day free trial - The Wheel — a photoreal antique astrolabe with a real Sun at its centre - Sky Today — the seven classical wanderers; tap any planet and fly it forward - Constellations — trace sixteen hand-drawn figures, map the sky, find the star the Sun stood before on the day you were born, and see this season's sky overhead - Your Numbers — four core numbers to read, and a fifth revealed through a celestial pinball table - Couple Mode — two rhythms side by side, and the days where they meet - The traditions — four ancient lenses, rotating daily - Every deeper view — the 90-day calendar map, the sky-note journal, free-text diary entries, filters, the long lookahead Cancel anytime — keep the free essentials, no rug-pull. FOUNDER'S EDITION — £29.99 LIFETIME Everything in Premium, forever. One payment, not a subscription. Plus a Founder badge and early access to new features. Limited to the first 500 supporters. HONEST BY DESIGN Astrology is a symbolic tradition. Numerology is entertainment. Biorhythms aren't medicine. Sothis tells you this clearly, then offers a reading anyway — a story to think about, not a verdict to obey. Real astronomy underneath — real planet positions, real moon phases, real spectral star colours, real constellation engravings from 1822 star atlases. Private by default — birth details, diary entries, partner info and cycle logs stay on your device. Cycle data is encrypted at rest. Ad-free, always. No tracking pixels. No selling wellness data. Made in the UK, made with care. hello@sothis.app Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period.
