Great Start (updated after map add on)

Ok, so the new version added the map and satellite overlay!! You get 5 stars for listening to your customers, including my old review below. Now if you add moon position you will get 6 stars ;)

After researching all the applications dealing with Sun positioning, I ended up going for Helios, yes... the most expensive. It does have the best and most intuitive features that I could see (compass, inclinometer and sky view) and it was the closest thing to sunPath out there. My main criticism is that for an app that costs $30 I would expect a bit more, specially Google maps interaction and possibly moon positioning as well. It is quite annoying to have to exit the app to check the satellite view on google maps to see the location you are in (or the one you want to shoot in). An overlay would be perfect, so I can see Google Maps satellite view over the sky view. Then this application would be perfect and a 5 star one too. There are apps like Focalware that offer "almost" the same for $10, so Helios has to step up a notch.
