    Great App! I enjoy the information it provides. I did find a small bug in the map section. I sent an email and it was fixed within a few days. Nice to see active support and communication. Thanks

    This is a fantastic app — as it always has been — it works very well with the latest (as of December 2017) iPhone OS. I especially like the customizable alarms which you can set for any number of celestial events. Keep up the good work guys!

    Enough said. I can plan trips based off the sun, and moon over a year in advance. I used multiple apps, but this is the easiest, and always accurate.

    It's actually closer to five stars — my only issue is that they never respond to my questions.
