***** New feature: Sun, moon and planet tracker *****
This feature shows the path of the sun, moon or any planet through the sky. This has many uses including garden planning, photography and even finding a shady spot to park your car.
The path is shown as a line on a compass disc, where the edge represents the horizon and the center is vertically up. You can view this on a road map, satellite map, or a plain background. Compass rotation is supported on the plain background.
***** New feature: Alarms *****
As well as setting simple notifications for events, you can now set up alarms so you'll never miss a sunrise photo opportunity!
***** Example uses *****
Here are some examples of what Sundroid can be used for. If you've found another use, let me know!
· Hunting and fishing
· Photo and film shoots
· Planning holidays and outdoor events
· Positioning solar panels
· Planning a garden
· Choosing a new home
· Parking your car in the shade
***** About permissions *****
In case you're concerned about permissions, here's what Sundroid needs them for. I'm happy to answer any question you have about security, so please feel free to get in touch.
· Internet access: Used to look up the name and time zone of your location, and for location selection using maps and search. Connects to Google only; there is no usage monitoring. Offline use is supported.
· Coarse and fine location: Allows Sundroid to get your current location (at your request) using GPS or networks.
· Prevent device from sleeping: Allows an alarm to keep sounding until you dismiss it. Otherwise it might be cancelled before you wake.
· Disable keylock: Allows Sundroid to show an alarm when the phone is locked so you can dismiss it without having to unlock the phone yourself. Keylock is re-enabled as soon as the alarm is dismissed.
· Start at boot: Alarms and notifications are cancelled when the phone is turned off, and this permission allows Sundroid to reset them.
· Control vibrator: For alarms and notifications.
· External storage: Google Maps uses this to cache map tiles for better performance. Sundroid does not read or write anything on SD.
· Google services: Required by Google Maps. Sundroid does not use it.
