SimpleMoon provides a simple, elegant view of one thing: the moon phase and illumination for today (or any day you choose). SimpleMoon also shows you when the next full moon and new moon will occur from the "Today" view.

So easy to use
Tap the navigation buttons at the top or swipe to move between days. Use the calendar icon at the bottom to choose what date you want to see the moon view and illumination.

Reliable and accurate
SimpleMoon uses advanced mathematical calculations to determine the moon data for that day. It works even if you don't have an internet connection!

Northern or Southern Hemisphere
Did you know that the moon looks different depending on which hemisphere of the earth you are in? Go to Settings and pick which hemisphere you are in, and you will see the moon as it appears to you in the sky.

Special thanks to my children, Alexander (15) and Sophia (12) who helped me design and test the app.

We hope you enjoy it!

This is a very simple moon app. It shows what the moon looks like for that particular day. You can flip backward & forward through the dates to see past & future dates. It lists the current date's phase & percentage visible, the date of the next full moon, & the date of the next new moon. SimpleMoon is exactly that... a simple moon app!!!
This app was exactly what I was looking for, but when I first downloaded it onto my iPad, it wouldn't rotate. I use my iPad in the horizontal position, but this stayed in the vertical position, even when i turned it to the horizontal. I contacted TAG ALONG K, to see if I might be doing something wrong. I received a reply THAT DAY, saying that it did NOT rotate, but he could most likely change it so that it would, & he would keep me updated! Kyle was very professional & kind, & he really did keep me updated!
Ten days later... it now rotates on iPads!!! YAY!!! Thank you so very much Kyle!!!!! Stellar job!!! Keep up the great work!!!

Simple Moon is as simple as it gets

Straight forward, simple. Automatically adjusts time of lunar activity to your device’s time zone-no mess, no fuss. This is my second time getting it as my first phone died a tragic death.
And fast- I forgot to mention its speed!

really keen!

So easy to use . No searching around for desired information. Great to have a photo for current moon view. Just download, open, and use. Good app for camping.
