Bug Reports & Fixes
Bug in versions 1.2.2 and earlier, September, 2016.
When running on iOS 10, the app will be unable to save some changes to favorite data and will create an error log.
This has been fixed in version 1.2.3.
Bug in version 1.2, June 29, 2015.
When the app is trying to make a larger font size on the Calendar, there is a problem calculating the size of the font for both
Astronomical and Nautical Twilights. This can cause the app to hang.
The workaround is to not select Larger Font Size on Calendar on the Settings screen when either Astronomical or Nautical Twilight is set to On.
This has been fixed in version 1.2.1.
Warning for iOS 8.3, April 16, 2015.
When the app is trying to create a new location or changing the coordinates of some locations it will crash without saving.
Earlier versions of iOS, 8.2 and lower, continue to work properly.
We are working on releasing a new version of the app, it will be a few weeks as we are also updating it for the iPhone 6
and 6 Plus. For now, the best workaround is to set a Red Pin (press and hold on the map on the Locate screen)
and tap that line in the Nearby Locations table so the calendar and times get created for the Red Pin coordinates.
This has been fixed in version 1.2 of the app.
Responses to Apple Store Reviews
Review: Great Presentation - Poor Data
by Rodentking - Dec 24, 2015
Okay, we are after the Winter Solstice and sunrise gets later every day according to this app. WRONG
Response: The latest sunrises and earliest sunsets don’t come on the winter solstice, the shortest day of the year.
For locations in the mid-latitudes of the Northern Hemisphere, the earliest sunset is in early December; the latest sunrise is in early January.
See the following article:
Why aren’t the earliest sunsets on the shortest day?
How To
Modify the Time Zone of a Favorite
- On the Favorites screen find the location that you need to fix.
For this example, Vancouver has the incorrect time zone and the wrong DST rule.
Vancouver is actually in the Pacific time zone (UTC -8:00) and uses the North America DST rules.
Vancouver has the wrong time zone and DST rule (underlined in red).
- Tap the circled i (circled in green) to bring up the Detail screen.
The Time Zone data is a button (circled in green).
- Tap the Time Zone button (circled in green).
The time zone list with the wrong one selected.
- Scroll down the list and tap (to select) the correct time zone: Pacific PST (-8:00) with DST: North America
Correct time zone selected.
- Click the "< Detail" button near the top to return to the Detail screen.
Newly modified time zone data is highlighted in yellow. Save button is circled with green.
- Click the Save button (circled with green) and click the "< Back" button and go to the Locate screen.
Locate screen.
- The location has now been corrected — all the screens in the app will use the new time zone and DST for that location.
Support
The Daylight Saving Time (DST) rules used by the app are the same as the SunriseSunset.com site. This page documents them.

Lectures
I highly recommend this series of class lectures by Brad Larson.
He is a fantastic teacher and I can virtually guarantee that if you are a beginner or
an intermediate iOS programmer you will learn a lot from this class (even though it is a few years old).
You will also see him contributing in the online community, such as stackoverflow.com.
