• New: Distance Off, in a new Coastal navigation menu — your distance from a lighthouse, cliff or charted peak by its vertical sextant angle, measured to its waterline or to the sea horizon, with every step shown • The vertical danger angle: the most the sextant may read to stay outside a clearing distance • Where a light rises or dips over the horizon: its distance from its height and yours, and a plain warning when it is too faint to be seen that far • Meridian countdown: 00:00 and "At its highest" now come exactly with the tone

• New: Meridian Passage — the time of noon for your DR, course and speed, and your latitude from the noon sight, with every step shown • A countdown to meridian passage, on your chronometer or the phone's clock, in UTC or ship's time — ticking faster over the last minute, with a tone at the passage • New: Latitude by Polaris — the Pole Star at any time of the night, worked out exactly (northern hemisphere) • New: Ship's time — set the zone your ship keeps; times are shown on the ship's clock • Noon and Polaris sights save to the logbook and cross with your other sights on the Fix tab • New: Twilight Stars — the best 3 to 5 stars for a fix at the next morning or evening twilight, with the altitude and bearing to preset the sextant; tap one to find it in AR Sky • A tidier menu: Celestial navigation and Compass checks, each opening and closing • Moon sights: parallax worked at the Moon's centre, so lower and upper limb agree

• Compass and Star Dome on iPhone keep turning after you come back from AR Sky • AR Sky's camera comes back after Control Center, a call or a notification • Numbers with a decimal comma (2,5) are read correctly everywhere • Rise, set and meridian passage: the next one is always the right day, near the date line and at high latitudes too • The compass waits for your position before warning of interference or aligning to the Sun • Night vision: AR Sky's buttons and panels are red too • Deviation card: the PDF prints every reading • Logbook CSV in UTC, opening cleanly in Excel • Many smaller fixes

• New: a compass — your heading, magnetic or true, with the Sun, the Moon and your chosen body on the dial • Find your phone's compass error by aligning it to the Sun or the Moon; AR Sky uses the same correction • Show calculation: every step of a sight reduction, with its formula • Smoother AR Sky • The Star Dome turns with your phone without needing your location • Choose whether the app opens on the compass or the home screen (Settings) • A short tour of the app, any time from Settings
