Lunar Phase calendar for Android

Pushing you to buy full version of the app which is money. Not a free app as its saying

I love using this app to follow the phases of the moon. The graphics are great! Only one thing prevents me from giving it 5 stars. Often I want to pinpoint the time of day when the moon will be fullest, or precisely when it reaches a specific phase. I can advance to future dates, but if I choose a specific time of day, the display will still show the current time. So if it's 11:00 a.m. now, and I advance to 2:00 p.m. three days from now, the day will change, but the clock still displays 11:00 a.m.

It would be great it to have this on the Google watch.

This would have been 5 stars except for a serious flaw. It does have the most beautiful UI you can imagine for such an app. I do a lot of serious Moon observing and I loved the fact that you could (apparently) enter any date and time and get the lunar day accurate to 1/10th of a day, However I discovered that although you can put in any date, the time always defaults to your current time. So if at 10:00 on the morning of Feb. 20th you’re planning for observing at 9:00PM that evening, it will show you the lunar day for the 20th but at 10:00 AM (even if you entered 9:00PM). For many astronomers, this flaw is so serious it’s a deal-breaker.

You can't scroll for more than a few days...really? Scroll for a couple days forward and if asks you to upgrade for $2.99. Omg unlimited scrolling for only $2.99?!? No way! Next full moon? Nope...you need to upgrade. 🙄🖕
