Stargazing Map: Star Finder

BinaryScript

À propos de l'application

🔭 Point your phone at the sky and it tells you what you are looking at

Hold your phone up. Stargazing Map draws the patch of sky your camera is facing
— the real stars, in their real positions, for exactly where you are standing
and exactly the time it is now. Move the phone and the sky moves with it.

⭐ WHAT IS UP THERE

• 8,922 stars — everything visible to the naked eye, down to magnitude 6.5
• All 88 constellations, with the joining lines that make the shapes readable
• 109 Messier objects — the Andromeda Galaxy, the Orion Nebula, the Pleiades
• The Sun, the Moon and all seven planets, computed live rather than looked up
• The Moon drawn at its true phase, with the lit side facing the real Sun
• Deep-sky objects drawn at their true size — Andromeda really is six full
moons wide, and the app shows it that way

👆 TAP ANYTHING TO IDENTIFY IT

Touch a star and it tells you what it is: name, constellation, spectral type,
how bright it is in plain words rather than a number, and when it rises, peaks
and sets tonight. Tap a planet and you get its distance in light-minutes and how
much of its disc is lit.

🔍 SEARCH, THEN BE POINTED AT IT

Look up Saturn, Vega, M31 or any of 440 named stars. The result tells you
straight away whether it is above the horizon and which way to face. Tap "Point
me at it" and an arrow leads you there, counting down the degrees as you turn.

🕐 TRAVEL IN TIME

Wind the clock forward and backward to see how the sky turns, or jump straight
to the end of astronomical twilight — the moment it gets properly dark tonight
at your location. Useful for working out whether a planet will clear the
rooftops before midnight.

🌙 RED NIGHT MODE

Your eyes take twenty minutes to adapt to darkness and one bright screen undoes
all of it. Night mode draws everything in dim red, which preserves that
adaptation the way an observatory torch does. Switch to the standard theme when
you are planning indoors.

📴 WORKS COMPLETELY OFFLINE

The entire star catalogue is built into the app. Nothing is downloaded, nothing
is fetched while you use it, and it works identically with the phone in
aeroplane mode. That matters, because the best places to stargaze are the places
with no signal.

🙅 NO ACCOUNT, NO SIGN-UP

Open it and look up. There is no login, no email, no profile, and nothing to
create.

📍 ABOUT LOCATION

The stars above Delhi are not the stars above London, so the app needs a rough
idea of where you are. It asks only for **approximate** location — never precise
— because moving a few kilometres changes the sky by less than the width of a
hair. Your position is used on your phone and never sent anywhere. If you would
rather not share it at all, pick a city from the list or type coordinates; the
app works exactly the same.

🧭 ABOUT THE COMPASS

Phone compasses drift, especially near metal, a car, or a laptop. If the sky
looks rotated, wave the phone in a figure of eight and it will re-calibrate.
The app watches the compass quality and tells you when this is needed rather
than letting you wonder why nothing lines up. Phones without a magnetometer can
drag to look around instead.

🧩 HONEST ABOUT ITS LIMITS

Uranus is at the edge of naked-eye visibility and Neptune beyond it — both are
drawn, but you will need binoculars. A live camera view behind the stars is
planned but not in this release.

🔒 PRIVACY

No account, no personal information. Your location never leaves your phone. The
app sends anonymous usage statistics and crash reports — the only thing that
leaves your device, and it contains no location and no object names.
