Zenit: Star Map & Night Sky

What is directly above you right now? Zenit answers in a glance. Open it and a hand-engraved star map turns to your night sky, with the constellation at your zenith, the brightest star nearest to it and the closest planet, all set in the style of an old star atlas.

Zenit is a quiet astronomy and stargazing app for people who look up. No ads, no account, and it works fully offline.

THE SKY OVERHEAD, LIVE
• A star chart of the whole sky above your horizon, centred on your zenith
• The constellation directly overhead, with its name and meaning
• The bright star and the planet nearest the point above your head
• Thousands of stars, all 88 constellations with their figures and boundaries, the Milky Way, the Sun, the Moon and the planets
• Turn your phone and the sky map turns with you, north, east, south and west
• Pinch to zoom: more stars and names appear as you look closer

TAP ANY STAR OR PLANET
A pocket star finder: brightness, distance in light years, altitude above the horizon and bearing. Learn astronomy one star and one constellation at a time.

TIME TRAVEL THROUGH THE SKY
Drag the time scale and the sky map travels up to five million years into the past or the future. Every star moves along its own measured path, and the slow wobble of the Earth's axis follows a modern precession model. See which star was overhead when the pyramids were built, or how the constellations will look when Vega is the pole star. Sun, Moon and planets are charted within 10,000 years.

KNOW WHEN THE SKY CHANGES
Optional notifications tell you when a new constellation, a new bright star or a planet reaches your zenith, only after dark if you like.

ZENIT PRO
A single in-app purchase opens the rest of the atlas:

• The almanac: tonight's sky at a glance in the panel and thirty nights ahead on a page of its own. Bright stars and planets crossing overhead, the Moon and planets meeting in conjunction, Moon phases, meteor showers at their peak, and lunar and solar eclipses, each to the minute for where you stand.
• A note at dusk with what the night holds, and a word about ten minutes before each event.
• Chosen moments: the night sky over any place on Earth at any date and hour, past or to come. A birth, a first meeting, a wedding night, the night you left home.
• My skies: keep those moments and return to them.
• Engraved plates: turn any sky into a custom star map, ready to print and frame. Vector PDF up to A4, a print image of 3508 × 4961 pixels, or a night sky wallpaper sized for your phone, with a dedication of your own and as many stars as you like.

A custom star map of the night you met makes a gift that lasts. Zenit makes it on your phone, from the real sky of that place and moment.

MADE WITH CARE
• Accurate to a fraction of a degree today, with star motions and precession for the deep past and future
• Works offline, like a planetarium in your pocket: the star catalogue, the places and the maps all live on your phone
• Location stays on your phone, and only approximate location is used. Or choose a place by name
• No ads, no tracking, no sign-in

SOURCES
Stars from the HYG Database (Hipparcos, Yale and Gliese catalogues), constellation figures from Stellarium, boundaries and the Milky Way from d3-celestial, Sun, Moon and planets from Astronomy Engine, meteor showers after the International Meteor Organization, places from GeoNames.

Clear skies and happy stargazing. Look up tonight; Zenit shows you what is up there.
