Sundial+ 101
Sundial+ provides a one-of-a-kind display of the sun and moon rise/set cycle over the 24 hour day. As the seasons change, the yellow “sun is out” arc informs you of the precious daylight hours: shrinking during winter months and expanding as summer approaches. The white inner arc represents when the moon is visible in the sky. Civil, nautical, and astronomical twilights are shown on the solar dial in shades of blue.Home Screen Widgets

Use of Location Services
Sundial+ requests your location while using the app to calculate solar and lunar times based on your
location. If you enable an alert (notification), it will further request your location "Always" (in the
background). This is requested to ensure any solar or lunar alerts that are scheduled use an accurate
location if you travel several miles or kilometers from where you last launched the app. For example, if you
travel to a new city, Sundial+ will be notified of your location change in the background and will reschedule
alerts based on your new location. Watch complications will also be more up-to-date in this mode.
Sundial+ uses a location mode that uses very little power: it only requests to be notified when a significant
location change occurs (via geofencing). For example, you travel a few miles/kilometers. If you go to the
Battery settings on your iPhone or iPad, Sundial+ may not even show up in the list unless you use the time
display and keep it open often. Getting occasional location updates and scheduling any enabled alerts just
won't use much if any battery life.
Sundial+ does not track your location or upload it to a server of any kind. See the App privacy policy.
