About this app
An accurate birth chart, because the math behind it is accurate.
If you have ever opened two astrology apps and read two different rising signs, the problem is not the sky. It is the math: an approximate time zone, a daylight saving switch nobody accounted for, and your whole chart shifts by a house.
Nadir computes positions with Swiss Ephemeris, the ephemeris used by professional astrology software, using the time zone and the daylight saving rule actually in force on your date and at your place of birth. Birth chart or natal chart, it is the same chart, calculated to the degree and the minute.
No generic sun sign horoscope, the same one for a twelfth of humanity. Everything starts from your natal chart and your birth time. If you do not know it, it is on the long-form copy of your birth certificate.
WHAT YOU GET
• The wheel of your natal chart, which you can zoom into: ten planets, North Node and Lilith, in signs and houses, plus the Ascendant and the Midheaven.
• Your chart ruler, its position, and what it changes about you.
• The five major aspects (conjunction, opposition, trine, square, sextile) with the exact orb, plus declinations (parallel, contraparallel).
• Your planet, sign and house dominants. Tap a bar and you see where its rank comes from.
• Your signature sign if you have one, computed on the ten classical bodies, with ties broken by the Ascendant.
• The transits to your chart today, with the orb and whether the aspect is applying or not.
• Synastry on four axes: Communication, Emotions, Energy, Values. Two people on the free plan, unlimited with premium. Family, friends, coworkers. This is not a dating app.
Everything is written in English, not rushed through a translator. French and Spanish too.
THE PART YOU CAN CHECK FOR YOURSELF
Every day, Nadir derives an energy score from 0 to 100 from your transits and names the transit carrying the most weight. Not "the stars are smiling on you", but "Mars trine your natal Venus, tight orb". You log how you feel in 30 seconds: energy, mood, sleep, stress.
Day after day, you get two curves side by side: what the sky said, and what you actually experienced. Sometimes it lines up, sometimes not at all, and you are the judge.
The score formula is additive, shown inside the app, and every statement comes with its own "Why?".

YOUR DATA
No ads in the app. Your data is encrypted and hosted in Europe, in Paris, and you can delete your account and everything in it from the settings. Nadir uses an install measurement tool (AppsFlyer), which reads the Android advertising ID to know where downloads come from.
WORTH KEEPING IN MIND
Nadir is a wellbeing and self-exploration tool. Astrology is not a science: it diagnoses nothing and does not replace medical or psychological advice. A chart describes tendencies, never a destiny. A score is not a prediction: it is a hypothesis about your day, and something you can check against your own experience.

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
What’s new
The sync with your watch only ran when you opened Settings. It now runs every time you open the app: last night's sleep fills in your daily feelings by itself, marked "Imported from your watch", right from sign-up. A value you correct by hand is never overwritten by the watch, and saving your feelings without touching it keeps the imported value.
