Not happy

I got this app hoping to predict where the moon will be at a specific time so I can plan moon photography locations in advance. Unfortunately, even while pointing my phone directly at the moon, the app’s predicted position is way off. Very disappointing, especially since I paid for the app.

An amazingly useful App!

This is my go-to app for planning photo excursions! This helps me figure out ahead of time where to position & orient myself ahead of any event. Thanks for a great app and keeping this up to date!!

Forced re-purchase

New version is worthless. Old version used to have ray tracing to view the light at various hours. New version has deleted that functionality & forced me to re purchase the app after using the old version for years.

The BEST app!!!

This app is an absolute must have for any Landscape Photographer! The first thing I did after getting familiar with the apps controls was to get on the map and Pin, and save all my favorite places, and places I plan on shooting in the future. That way I can use my ipad offline at any of the locations and still be able to use all the calculators for sunrise and set, and moonrise and set. And also be able to track the stars! You will be able to plan when and where you want to shoot months ahead. ABSOLUTLEY INVALUABLE!!!
