I am an astronomy journalist and public speaker who bought this app with glee, assuming the folks behind Dark Sky Finder or the original datasets had developed an app that lets you display all the data from the above locally.
This would have been hugely beneficial to me as a tool to show the public how dark a site is from the site, as well as finding out for myself how dark a site Im at actually is.
Sadly, the developer seems to have done nothing more but wrap the existing web page in a fancy package, throw it on iTunes, and let the $ roll in.
This app doesnt even display some of the light pollution graphics/data that the online version of Dark Sky Finder does.
Dark sky info for the first two dark sky preserves I zoomed in on (Kejimkujic National Park east of Halifax, and Jasper National Park, the worlds largest dark sky preserve) werent even available in this app by default (an email to the developer revealed that you can choose a map that will show all these areas, though no info is clearly provided to users for how to do this.)
Most disappointingly, the app only works with Internet access - WTF?? If I had Internet access, Id just go to the Dark Sky Finder site (rather than clutter up my device with one more app Ive got to find a place for, update, etc...)
To the folks who developed this app and let it rise through the Google rankings until it showed up along with the Dark Sky Finder site: Do the right thing and either offer an "offline-friendly" version or scrap this ill-conceived cash-grab.
