• The calendar now shows every day of the month — months starting late in the week were missing their first days • Hourly weather and the Stargazing Index now work with every calendar system, including Buddhist • A refreshed welcome screen with facts you can check in the app • Better on iPhone Duo: when folded, tabs move to the side and the welcome and subscription screens fit without scrolling; when unfolded, Tonight and Calendar are easier to read in a single column

A much bigger sky. • 86 real photographs: zoom in on a bright nebula or galaxy and its actual image appears. ESO's panorama of the whole Milky Way is a new layer behind the map. • Zoom in and the stars keep coming — 74,000 more, down to magnitude 9. • Zoom further and a planet stops being a dot: Venus in phase, Jupiter with its four moons where they really are, Saturn's rings at tonight's real tilt. • Satellites are drawn at the brightness they will really have as they pass. • An encyclopedia built in — 300+ written entries on the planets, all 88 constellations and their myths, every Messier object and the brightest stars. • Guided tours that walk you across the sky, a stop at a time. • The calendar now finds real events: eclipses for your own location, conjunctions, oppositions, elongations, equinoxes and supermoons. • Deep sky grew from 3 objects to 1,800. Comets, planet moons and 150+ satellites arrived with it. • New map layers — constellation figures, boundaries, asterisms, the Milky Way, grids, the ecliptic and a real horizon. • The Moon is drawn in its true phase, and every planet in its own colour. • Time Machine — scrub to any date and watch the whole sky move with it. • Widgets, an Apple Watch app, and a proper iPad layout. • Sky news, sharable object cards, and optional event reminders. • Two map modes — Light stays smooth on any phone, Detail turns everything on. • A new opening: the solar system exactly where it stands today.

Sharper AR • The sky now tracks with ARKit — steady, instead of drifting with the compass. • Drag the sky to line it up with what you see; your alignment is remembered. • More precise Moon and planet positions, and the overlay matches your camera's field of view edge to edge. • Fixes and polish throughout.
