Suntime — Sun Moon and Planets

Suntime is a minimalist timeline calendar that connects you to the cycles of the Sun, Moon, and planets. Swipe to navigate through time, zoom the timeline to see movements at different scales, and quickly spot rising and setting events, moon phases, and planetary alignments. The app includes notes on the timeline, home screen widgets, and customizable alerts for 25 solar and lunar events, from sunrise and solar noon to moonrise and eclipses.

It runs on-device for offline calculations and is ad-free and privacy-respecting. Suntime supports portrait and landscape modes on iPad, uses your location or a manual one, and includes a glossary and contextual tooltips for Moon position, illumination, eclipse visibility, and twilight lengths. Alarms are scheduled with Background App Refresh, ensuring a lightweight, unobtrusive experience.
