Great App

Really useful app for checking on sun and moon phases.

Good app

I like this app.

The “Tides” of the Year Everywhere

I have been using LunaSolCal for many years now. It fits perfectly into my life of writing letters all over the world to people in all climes. I love to compare their longest days, longest nights, the Moon’s rising and setting, the length of days, you name it!

This program allows me to do that, to the second, something most websites do not provide. My Asperger’s brain loves details, another way in which this is perfect. It’s science in a neat package and I can find any location my friends live.

When I have questions, the designer takes time to help me, and invaluable help. I very much appreciate that. (My apologies for when I thought daylight saving time was made permanent — that was me, entirely. I keep hoping the powers that were (are?) will jump the United States an hour ahead, stop this nonsense of moving time — I really need the missing Sun in the winter, here in New Jersey…!)

If you love science, the dance of the Moon, Sun, when different events of the normal day take place, then you will adore this! LunaSolCal takes all of these tidbits into a beautiful app that will give you all of that information. It also has been developed for iPhone, iPad and MacBook!

I cannot recommend it enough.

One of my all time favourite go to apps

I purchased this app back in 2010 for my Samsung Galaxy tab 10”. In that time I switched over to iOS and I’ve always kept this app on my phone and iPad ever since. That’s 14 years plus on iOS. I really appreciate that the developer still maintains this app and still gives it regular update. For people who were obsessed with sun/moon rise/set times from all over. You must get this app.
