The sky in your hand — the Moon's 28 mansions, your Firdaria periods, and a living astrolabe of the Islamic Golden Age.
How it works
The same short walkthrough shown the first time you open the app:
✶ Falak — A living astrolabe in the tradition of the Islamic Golden Age — real astronomy, computed for your place and moment. Measuring the sky, never surrendering to it.
Each Night Has Its Flavour — The Moon rests in one of 28 mansions — the manāzil — each night, every mansion with its guiding star and its own character. Tonight's mansion sets the day's practice.
The Living Day — The astrolabe ties the sky to the day as the Golden Age astronomers did: the five prayer times and the planetary hours, all computed from the Sun and stars over your own horizon.
Ask Anything — Ask about tonight's sky, the Moon's mansion, a star's name, or the tradition of celestial science — your location and mansion are already in view. Plain language, any time.
Walk the Path — muḥāsaba, in a modern form. Read tonight's mansion and its character, do each day's short practice, and watch your five-quality star grow — Resolve, Mercy, Connection, Authority, Patience.
Add Your Birth Date — Your Firdaria — the seven planetary periods of life, in the tradition of Abu Ma'shar — colour every daily practice with the period you are living now. Optional, and everything stays on your device.
Getting started
Open the Today tab — it shows tonight's manzil, the lunar mansion the Moon occupies right now, and the quality classical astronomers read in it.
Take the daily practice — a short scenario woven from the current mansion (and, once set, your own Firdaria period).
Add your birth date in Settings to unlock your personal timeline — including whether you were born by day or night, which changes the traditional order of your periods.
Return to the Chart tab to see your full Firdaria sequence and where you stand in it today.
The tradition behind it
Astronomers of the Islamic Golden Age — al-Bīrūnī above all — mapped the Moon's monthly journey through 28 manāzil al-qamar (lunar mansions), each with its own character, and divided a life into Firdaria: planetary periods that colour each stretch of years. The app computes the real Moon position and your real periods, on your device.
Readings are grounded in al-Bīrūnī's Book of Instruction — the classical source itself, not a paraphrase.
What's inside
Manazil
Tonight's lunar mansion, computed from the actual Moon — with the day's practice built on it. Tap any of the 28 for what it means.
Astrolabe
The classical instrument, alive: current sky, prayer times, and upcoming eclipses.
Firdaria chart
Your planetary periods from birth — day-birth and night-birth orders respected, as the tradition requires — exportable as PDF.
Ask
Question the tradition directly; answers draw on al-Bīrūnī's own text.
Morning guidance
Optional morning notifications tell you which mansion the Moon has entered — composed on your device, opt-in, off any time in Settings.
Subscription
Falak offers a free trial period, after which a low-cost subscription unlocks full personalised access. Exact pricing and any current offers are shown in the app at the point of purchase, and via your device's app store account settings.
Privacy
Your birth date never leaves your device except as part of the prompt used to personalise your reading — no account, no identifier. Read the full privacy policy.
Common questions
Why does day or night birth matter?
Classical Firdaria begin the sequence with the Sun for day births and the Moon for night births. It's not cosmetic — it changes which period you're in today, so the app asks and respects it.
Is the Moon position real or symbolic?
Real. The app computes the Moon's actual ecliptic position with an astronomy engine and maps it to the mansion — the same observation the classical astronomers made by eye.
Does it work offline?
The astrolabe, mansions, and Firdaria are computed on the device. The daily scenario and Ask need a connection to our generation service.
