Great concept;app has glitches

I love the concept of this app., and the graphics showing just how much daylight there is on any given day of the year. The information that is supplied dawn and dusk times is excellent. But, for some strange reason, it will not allow you to add additional locations, even after you delete other saved locations — in the dropdown menu, which it used to do just fine, and that is disappointing.

What a great idea!

I love this interesting & beautiful app! 1-hand clocks are rare to find. This one adds some extra touches: a "24" on the dial & differentiated shadings for civil, nautical & astronomical twilight. The data table with detailed times can be very helpful for planning purposes & the icons & fonts are to me very aesthetically pleasing. I have 2 suggestions: 1. What about adding a option to hide the data table? Sometimes I want to know the exact times, but sometimes I just want the sense of calm that only a 1-hand clock can provide. 2. What about adding a widget, perhaps as an in-app purchase? Thanks, Michal & Hana, for your efforts on this app - it really shows!

Very beautiful and comprehensive

This is a really nice app. There are a number of apps that display sunrise and sunset information. I like this one for the amount of detailed information provided in a well organized way, and the very attractive interface. I earlier wrote a critical review because the date was not correct. This issue has been solved, and the developer sent a message to let me know! So, check the date on any reviews complaining of this problem, it might be an older review and the person may not have updated their app or their review. I am on a iPhone 6s running iOS 10.2.1.
