Nice app, need data too

I purchased this app because I loved the data on the website and wanted to access it on my smart phone. Sadly the app only shows on a map the time, date and light cycles.

I would love to see the data of sunrise & set, moonrise & set, length of days, etc. of a given location as it is on the website. I still give it four stars as I like the quality of what is here.

Please add the data table!

Stunning Work of Art

and a valuable tool for tracking the state of light anywhere around the world - especially critical for traveling photographers. Most of all, I just find it a beautiful reference tool. Wall mounted units with less utility have sold for thousands of dollars for several decades. I could never afford a wall unit, but now I have Say and Night!

Fantastic and Educational!

I've been using this app since 2013, and I can say that this app is very educational and handy dandy if you like keeping track of where the sun is over the course of a year.

And the $1.99 upgrade is definitely worth it... As it makes this app useful in tracking down solar eclipses.

The only downside is that this app has not been updated since 2012, and as such, there are a couple issues:

This app is not optimized for the bigger screens of the iPhone 5 and newer,
And since iOS 9, the eclipses menu no-longer shows the date of the given eclipse. but still works otherwise.
