The dial now shows the night itself: it runs from sunset to sunrise, with true darkness and the best hours drawn brightest, and the score in the middle. When the best hours fall under a bright Moon, Nyx says so rather than drawing them as dark sky.

One best night everywhere: a park's page, Tonight, Best nights and the calendar now name the same best night and the same score. Lists that look only at the next seven nights say "Best this week".

The answer comes first: a closure sits right under the score, and "I'm going" is on a park's first screen. Tap a night in the calendar to keep it or open it. Past weeks in the month fold away. When moonlight caps a score, the page says so in plain words.

Night vision's red is now readable for red-blind and green-blind eyes too, and still deep red. Settings › Red light for the whole iPhone shows how to turn every screen red with iOS's Color Filters, menus and keyboard included.

Motion, refined: pull down on Tonight and a star gathers under your finger before a meteor carries it away. The Moon above the 30 nights changes phase as you scrub, the score starts counting as the app opens, and its four parts fill in under it. With Reduce Motion on, changes now fade instead of cutting. On Apple Watch, the score rolls as you turn the Crown, and the dial keeps its size.

New in 2.10: drag sideways across Tonight's dial to step through the next two weeks; the darkest place in reach and its score follow your finger, and VoiceOver can step night by night. Night vision can now turn on at dusk where you plan from and off at dawn, at the same minute on iPhone and Apple Watch. And each park in the list shows how many of the Little Dipper's seven stars you would likely see, an estimate from its sky glow and the Moon.

Also: the sky chart steps hour by hour with VoiceOver, larger buttons step through the 30 nights at the largest text sizes, the journal editor is calmer, and on iPad a journal entry uses two columns.
