Everything you need to read the night sky

Planets, stars, constellations and deep sky objects, all worked out live for the exact spot where you are standing.

Point and find

Lift your iPhone and the camera view labels what is really above you. Pick a target and an arrow walks you to it.

Tonight at a glance

Everything visible from where you are right now, with rise, transit and set times and a plan for when the sky gets dark.

Ask PlatonAI

An astronomer built into the app. It answers for your location and the hour you ask, not with a page from a textbook.

A sky map with real depth

Pinch to zoom and thousands of faint stars come out, the way they do through a telescope. The map turns with your compass.

Sky events and NASA's photo of the day

Moon phases, meteor showers, eclipses and conjunctions with reminders, plus a new space photo from NASA every day.

Six sky games

Games built around the real night sky that help you learn the constellations. One of them is free every day.

PlatonAI

An astronomer who can see your sky

PlatonAI knows where you are, what time it is and what is above your horizon right now. Ask what that bright light is, what is worth seeing tonight or how to photograph the Moon with your phone.

Pro PlatonAI is part of Pro and answers in the language you use the app in.

What is that bright star in the west?

PlatonAI

That is not a star, it is Venus, about 18° above your western horizon. It sets in roughly two hours, so look now while it is still clear of the rooftops.

How it works

  1. 1

    Allow your location

    The sky looks different from every place on Earth. Your location makes the map match what you see.

  2. 2

    Lift your iPhone

    The camera opens and every planet, star and constellation is drawn onto the real sky.

  3. 3

    Tap and follow

    Tap anything to see what it is and when it rises and sets, or let the arrow guide you to it.
