Few kilometers away and the sunset already a few minutes different. Don't worry about battery drain, the widget uses the last location if available. Only updates when the screen is on every 30 minutes; or when you tap it.Any feedback is warmly welcome and will be taken into consideration!The Android robot is reproduced or modified from work created and shared by Google and used according to terms described in the Creative Commons 3.0 Attribution License.
