I live next to Yosemite National Park and take plenty of moon pictures here. This app is perfect for landscape photographers like myself to determine the upcoming moon phases, the elevation, azimuth, etc.
I am completely satisfied with this app and all its features. Dev Team, please do NOT remove any of the current features. I love and use them all.
The developers just updated the app today (bug fixes) and it works very well on my iPhone 6S+ as it did on my iPhone 5 and 6.
I highly recommend this app.
