Sun Surveyor (Sun & Moon)

★★★★★ I have been using Sun surveyor for iPad for many years. Since recent installed it on my GEAAC Z70 military specs' tablet because of its professional GPS unit. This combination : Sun surveyor with the GEAAC make it the very best Sun / Moon / Milky way surveyor ever. I also have Planit Pro and Photo Pills installed. Neither of them comes even close to the incredible user interface of Sun surveyor. The accuracy of the app is as good if not better as the others. But as said the user interface is just the best of the best. All the information required to read and adjust settings in one screen without ever having to hop from screen to screen and back is just such a time saver. I use the app for my landscape and architecture photography and every now and then for scouting camp locations to see where I will have Sun or Shadow. It simply never fails. The app is not bloated with all kinds of extra info like 'magic' curves of Sun or Moon paths but gives you exactly that what is needed for the job. Over the years I had some contact with the developer Adam Ratana, always a most peasant conversation, and he proved to be very open to small suggestions. I am a professional photographer with 40+ years experience - now 'legally' retired and often realize that thanks to apps like Sun surveyor I can make better photos where in the past even after a lot of endless calculations - I could just, just miss 'the moment' the Moon for instance showed its face over a mountain. 100% recommended - don't be blinded by the marketing of the big colorful app makers. Surveyor really shines !!

★★★★★ March 2023. Update: This is still in my top three apps for dialing in astrophotography planning. 2018: I have a few sky apps. I keep coming back to this one, though. It's the best organized, best compass, most accurate information for my needs. Thank you. Over a year now as a happy customer. :) Update: 8 Apr 18 ...still my go-to app. Three days from an epic trip to New Zealand. Sun Surveyor, and Google Earth are my two main tools for shot planning. Best app! Thank you.
