NASA-precise sidereal astrology.
Your daily wellness ritual.
Traditional astrology uses seasonal frameworks that ignore 2,000 years of celestial drift. Your planets may not sit where older tropical frameworks place them. Nyle & Moon calculates your chart using NASA JPL ephemeris data and the Lahiri Ayanamsa, so every planetary position reflects where it physically sat in the sky the moment you were born. We provide a true-position sidereal birth chart.
From that scientific foundation, we built three experiences: Your Sidereal Birth Chart, a psychological mirror revealing your core blueprint. A Daily Soul Dashboard offering daily cosmic energy scores, wellness rituals, cosmic food recommendations, sound healing, and transit breakdowns. And for couples, The Union, a live relationship dashboard mapping your 28-point Vedic compatibility and suggesting celestial-timed dates and intimacy rituals.
Here's something most astrology apps won't tell you: your Sun sign is probably wrong. Earth wobbles on its axis, slowly, about 1° every 72 years. Over the last two millennia, that wobble has shifted the zodiac by nearly 24°. The framework most apps still use was accurate around 100 AD. It's not anymore. Your "Scorpio Sun" might genuinely be in Libra. Your "Leo Moon" could be sitting in Cancer. It matters.
Nyle & Moon calculates your chart using True-Position Sidereal Astronomy, the Lahiri Ayanamsa correction applied on top of NASA JPL DE441 ephemeris data. That's the exact same planetary position engine NASA uses to navigate spacecraft to Mars. We map all 9 Vedic planets across the 12 houses of your chart, then break down each one with a tap, explaining what that planet means in your specific house, your specific sign, your specific life.
"This isn't a personality quiz.
It's a psychological mirror built from the physical reality of space."
What's inside your chart
Invite your partner and unlock a private relationship universe. The Union is a live dashboard that tracks the shifting chemistry between two sidereal birth charts. It combines daily and weekly intimacy quests, a real-time relationship weather board, 28-point Vedic compatibility scoring, and a celestially-timed date planner into one shared space.
Complete intimacy quests together to build communication and closeness, then track your progress on a shared leaderboard with streaks. The Relationship Weather Board shows your daily emotional, communication, and physical alignment scores. The Cosmic Date Planner finds the best planetary windows for connection and suggests restaurants near you. And underneath it all sits Vedic Compatibility, scoring 28 points of relationship chemistry across 8 dimensions.
"Not a compatibility quiz.
Mathematics."
Tools for two
Most apps tell you your sun sign is Libra and call it a day. We track 9 actual planets against your birth sky and tell you why today feels heavy, and what to do about it. Every day, the planets move. They form angles to each other and to the exact positions they held at the moment you were born. Those angles, called transits, are the engine behind your daily emotional weather.
We calculate every single one of them for you, in real time, and turn them into something you can actually use. Your Cosmic Pulse, an Energy Index across career and love, a personalized Mind & Soul Protocol, tailored Sound Therapy frequencies, and transit-aware wellness insights. All of it calculated from your chart, not from a database of generic advice.
"You're editing your own story before anyone asks to read it."
That's Saturn conjunct a Last Quarter Moon. We tell you why, then what to do about it.
Your daily toolkit
Deeply layered guidance,
built on real astronomy.
Nyle & Moon uses sidereal astronomy with mathematically precise planetary positions from NASA's Jet Propulsion Laboratory. Most apps rely on the tropical zodiac, a framework that has not accounted for 2,000 years of celestial drift. We show you where the planets actually are. The difference? Your Sun sign could shift by an entire sign.
NASA JPL Ephemeris
We pull live planetary coordinates from the same dataset NASA uses to navigate spacecraft. No shortcuts, no approximations. The same precision that guides missions to Mars tells you where Saturn actually sits in your chart right now.
Lahiri Ayanamsa
Earth wobbles on its axis, slowly, about 1° every 72 years. Over 2,000 years, that drift adds up to roughly 24°. Most astrology apps ignore this entirely. We apply the Lahiri correction so your planets land where they genuinely are in the sky tonight, not where they were in 100 AD.
Guna Milan Scoring
This is not a "are you compatible?" quiz. Guna Milan is a centuries-old Vedic scoring system that evaluates 8 dimensions of a relationship: emotional wavelength, instinctive attraction, mutual respect, and temperament, all derived from the exact Moon placement in both charts.
