SunApp

about

description

SunApp calculates sunrise, solar noon and sunset for any location on Earth, handles the timezone properly, and says plainly when the sun does not rise or set at all. It can also wake you by the sun rather than by the clock. Set an alarm for six hours before solar noon, or eight hours after sunrise, and it recomputes every day as the seasons move. When you build a rule it shows you the next thirty days of fire times, so a rule that drifts to the afternoon in December is visible when you set it rather than discovered in November. During polar night it falls back to solar noon and tells you why. It never touches the network. There is no INTERNET permission, so it cannot, and there is no location permission either: coordinates come from a bundled catalogue of 25,007 cities or from numbers you type. Check for yourself: aapt dump permissions SunApp-v1.1.0.apk The nine permissions you will see are for the alarm feature and are documented one sentence each in the repository README. Sun times need none of them, and no dialog appears until you create your first alarm. - Search 25,007 cities, accent-insensitive in both directions: "tromso" finds Tromso with the slash, "Herat" finds the one with the macron. English exonyms work too, so "Gothenburg" finds Goteborg and "Cologne" finds Koln. - Every city carries its own IANA timezone. Times render in the place's zone, not your phone's. - Any date, past or future. - Midnight Sun and Polar Night are detected geometrically and labelled, not shown as a blank or an error. The same maths and the same catalogue run on the web at sun.stormberry.as, and the Kotlin port is tested against a golden corpus generated from the JavaScript one, so the two cannot silently disagree about when the sun comes up. Built by Stormberry AS in Askoy, Norway, where the gap between a December sunrise and a June one is nine and a half hours and the question stops being academic.
