About

SunMoonFox

Read full description

SunMoonFox is a quiet daily practice. Each day, draw a card from the 36-card Lenormand deck and carry its elements with you - symbols to notice, themes to attend to, threads to follow through your day. The practice is simple. The cards offer you a small set of elements drawn from numerology and the natural world: fire, water, earth, air, alongside themes like loyalty, change, hope, or stillness. Throughout your day, watch for moments that resonate with these elements. When a moment lands, capture it in your diary. Over time, the diary becomes an archive. Past cards, past moments, recurring themes - all visualised as a living constellation of suns and planets. Patterns surface. Synchronicities reveal themselves. SunMoonFox is for those who suspect the world is more responsive than it appears, and who want a structured way to test that suspicion. WHAT'S INSIDE One card a day, drawn either virtually or logged from your own physical deck. The full 36-card Lenormand library, with elements, descriptions, and history. A diary for capturing synchronistic moments, with automatic tagging of elements, numbers, and people you choose to track. An archive that maps your journey as a constellation — see which themes recur, which moments connect across days, which patterns emerge. No accounts. No tracking. No advertising. All your data stays on your device. The ritual is yours. WHO IT'S FOR Anyone drawn to tarot, oracle decks, or contemplative practice. Anyone interested in noticing more than they currently notice. Anyone who has felt that strange tug of coincidence and wondered what would happen if they paid closer attention. HOW IT WORKS Draw once a day. Choose virtually or use your own physical deck. Carry the card's elements through your day as gentle prompts. When something resonates — a conversation, a sign, a feeling - capture it in your diary. Watch the archive grow into a map of your attention. SunMoonFox is free to use. There are no subscriptions, no in-app purchases, no hidden costs. Just a daily card, and the quiet work of paying attention.
