Very useful

Are use this app a lot. It has a wealth of data that is not usually available on Weather apps and things of that nature. It is very stable and that means a lot to me. I believe that you may be well advised to consider it.

Beautiful in its simplicity

A no fuss, no frills approach to basic time, navigation, and weather data. The main screen has all the essentials in an easy to read layout.

The Moon Phase goes back only to the year 2000, not 1900

I tried to look at my birthdate for the moon phase, and when I changed the year, it immediately changed it to the year 2000. All years previous to 2000 are grayed; obviously meaning there’s no information for them.

Developer Response ,

Moon phase dates are available from January 6, 2000 forward, as noted in the app description. We will look at the calculation to see if we can go back further.
