SunMoon computes rise/set times of the sun and moon for your GPS location. Also: solar noon time and sun altitude, sun alt/az, moon phase.

Advanced users my like AdvSunMoon: can choose location from map instead of only local GPS location; GPS not needed: will use last loc.  DE, EN, FR, ES languages, AM/PM time, Help info.
