Ratings and reviews

Excellent app. Can tell a lot of time was put into it. The amount of customizations are overwhelming which I love! If I can make one suggestion, it would be me if there was a way to put a marker on the outer number or marker dial for solar and a lunar noon. I know there's the culmination option but I would love just a marker on the numbers to make it more minimalist. Again, excellent app. Well done.

A must for outdoor work, recreation, gardening, hunting, etc. For anyone who works outside, this app is more valuable than any other clock or schedule. How many times have I had to figure out when the daylight would be enough to start work, or when the dew might burn off, or when I needed to start packing up. Twighlight & moonlight really do make a difference. Suggestion: a daylight-centric alarm would be a plus.

Without a doubt the best clock in the world! There is nothing even close. It can show all six kinds of twilight and even sundial correction on a hand of its own! Unbelievable! There is only one item on my wish list: An alternate hour-hand that can be set to UTC would make this perfect for ham radio use. I know I could set the clock to run on UTC time, but then I can't use the locality dependent astronomical features. Such a great job, you can be very proud indeed.
