Sunclock Customer Insights

1. Some suggestions: allow the "Home" and "Abroad" labels to be customized; allow an abbreviation for which twilight option is displayed; provide a UTC display option.An excellent way to visualize time! Short of letting us freely segment the day into blocks (awaken, productivity, recreation, wind-down, sleep, etc) it has every customization option I could need.

2. Although I have modified default settings to personal preferences, can't figure out how to display those in home screen widget...not yet, but I will.

3. Edit: moon phase is not shown how I'm used to, but now that I read the instructions... Thanks! ☺️Wonderful app! Attractive, uncluttered interface yet so many useful functions.

4. It shows times of the blue hour and golden hour for photographers, shows important times of the day for those of various religions including the inauspicious times for new ventures, shows the direction of Mecca for Muslims, so much more.

5. My only complaint is that I found the night displays intuitive when viewing the 12 hour clock; I expected the times to line up with the clock, which they don't.

6. There are a number of these on Play Store, but this one's widget never freezes and it is by far the most attractive of them all.I was really surprised, but this clock is actually a big improvement.

7. It can show all six kinds of twilight and even sundial correction on a hand of its own! Unbelievable! There is only one item on my wish list: An alternate hour-hand that can be set to UTC would make this perfect for ham radio use.

8. There is no way to save/apply a custom clock theme other than to copy the settings as a txt file and paste them into a notepad.

9. I gave it 3 stars because in the pictures it shows the app can be used in the locked screen.

10. Now that I've got it set up to my needs it's great! There are ads in the app, but they run along the bottom, never interrupt you, & disappear if you use the widget (or pay the dev for their work, as you always should if you can).

11. I know I could set the clock to run on UTC time, but then I can't use the locality dependent astronomical features.
