SunApp for Android is out, and it wakes 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 into 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.
25,007 cities are compiled into the app, each carrying its own timezone. There is no
INTERNET permission, so it cannot phone home even if it wanted to, and no location
permission either. You can check that yourself before installing.
MIT licensed, and the same maths runs in the browser if you would rather not install
anything.
A functioning prototype built in Askøy, where the gap between a December sunrise and a
June one is nine and a half hours and the question stops being academic.
