Customer Reviews

Well done

The UI looks great, good job on the iOS 7 redesign. Still my go to App over the years and recommend everyone should download and then pay to remove ads to show props.

Would be great to see the app universal for app (I would pay a few extra few bucks).

Would also like to see a better night sky render, something you can pinch to zoom to match scale of your sky, and label some of the major stars, so that is it easier for more novice sky lovers to identify the night sky.

I use this app to photograph the IFs and ISS, sometimes because I am unsure of position I need to make last second corrections and sometime miss the event.

Great app keep the updates coming!
