Planet Finder: Tonight Sky Map

Point your phone at the sky and Planet Finder tells you exactly what you are looking at.

Planets, stars, constellations and deep sky objects, all worked out live for the precise spot you are standing on. No account, no sign up, no waiting.

Ask PlatonAI anything!

An astronomer built into the app. Ask anything about tonight and get an answer for your location and the hour you are asking, not a page from a textbook. It knows what has already set, what is still climbing and what the Moon is about to wash out.

POINT AND FIND ANYTHING
Lift your phone and a pointer walks you to any planet, star or constellation. The camera view is labelled with what is really above you.

TONIGHT, AT A GLANCE
Everything visible from where you are right now, with rise, transit and set times, and a plan for the moment the sky finally goes dark.

A SKY MAP WITH REAL DEPTH
Pinch to zoom and the map keeps going. At the deepest levels thousands of faint stars come out, the way they do through a telescope. The whole map turns with your compass.

THE COMPLETE CATALOGUE
All 88 constellations. 196 named stars. The full Messier catalogue of 110 galaxies, nebulae and star clusters. Real NASA photographs of the Sun, the Moon and every planet. The Milky Way drawn across your own sky.

A CALENDAR THAT TELLS YOU WHEN
Moon phases, meteor showers, conjunctions, eclipses, oppositions, greatest elongations and supermoons. Set a reminder, or add any event to your own calendar with one tap.

SIX SKY GAMES
Games built around the real night sky. One of them is free every single day.

MADE FOR REAL NIGHTS OUTSIDE
Red night mode protects your night vision. The astronomy is computed on the device, so it keeps working with no internet at all.

PLANET FINDER PRO
Pro opens PlatonAI, the entire catalogue, unlimited AR finds, the deep zoom, every game, red night mode, a best viewing card you can save and share, and the ability to pin your own photo onto any object in AR.
