SunTrace: Sun, Moon & Stars

SunTrace visualizes the sun and moon's journey across the sky in a beautiful, minimalist chart — right on your home screen.

NEW IN 1.3
• Tonight Score – tonight's stargazing score from 0 to 100, with the best 2-hour window and the reasons behind it (7-night outlook with Pro)
• Milky Way planner – when the galactic core is visible tonight and this month, plus a Milky Way band on the sky map and in AR (full-year heatmap with Pro)
• Real terrain – the sky map and AR draw the actual ridge line around you: "Hidden behind the ridge, clears at 10:10 PM"
• Star-hop guide – step by step from bright stars to the constellation you want
• Constellation photo – in camera AR, show just one constellation's lines and name, take the photo, align it, then save or share. Free photos carry a small SunTrace watermark; Pro removes it. Phone cameras mostly capture the brighter stars.
