Point. Find. Learn.
Find anything
Search by name, designation or coordinates, then follow the arrow on screen until the target is centred.
Learn what you're looking at
Tap an object for a photo, a description, key facts and when it rises and sets where you are.
Travel in time
Run the sky forward or back, from the year 1600 to 3000, or jump to the next sunset, full moon or eclipse.
Night mode
A red-shifted display that keeps your eyes dark-adapted at the eyepiece or in the field.
Version 2
Rebuilt from the ground up
Sky Map 2 is a new app with a new sky renderer, the same free price, and fewer rough edges.
Rise and set times on every card
Planet, star or galaxy: see when it next rises and sets where you are, and whether it never sets at all.
A pointing readout
Right ascension and declination, altitude and azimuth, and the field of view, live on the map.
Tap to identify, out of the box
Tap any labelled object for its card. It was switched off by default in v1.
Eclipses at the right time
The Sun and Moon are computed far more precisely, so an eclipse peaks when it actually does.
Venus and Mercury have phases
Zoom in and watch them wax and wane, instead of flat, fully lit dots.
28 languages
Fully translated, help included.
