Phone screenshot: Main Activity

When you first open Moon Phase Pro, you're presented with an image of the current moon, big and beautiful. This highly realistic simulation accurately depicts both the phase and crescent angle as seen from your location. Near new moon, it even simulates earthshine on the dark side.

The app's main screen also shows key information about the moon right now: its phase percentage and name, the time until the nearest syzygies (new and full moons), and the moon rise and set times bracketing the present. All the essentials, at a glance.

This view of the moon is fully interactive. Drag your finger over its surface and the lighted area moves with your touch; stop dragging, and the data fields will update to indicate on what day the moon will look like this. Drag with two fingers and you'll spin the moon instead of the shadow, to get a look at the far side or the lunar poles.

You can also go directly to a date & time of interest by direct entry, or change your "observer" location to see what the moon looks like from the other side of the earth.

And there's an option, shown in this screenshot, to draw the shadow of every crater and mountain on the face of the moon individually – and move them as the phase changes. We call it maximum realism, and you can find it in the app's Settings screen.

Finally, you can share the moon with your friends. Moon Phase Pro integrates with other apps on your device to send either a copy of the screen, basic moon data, or both (depending on the functionality supported by the sending app).

Tap the navigation menu at the upper-left for additional functionality. First on the list is Moon Phase Pro's Calendar, showing the entire month's phases at once. The current day is highlighted, as are the dates of major phases: full, new, and quarters. For the big picture, tap any day and it will open full-screen.

You can also easily skip to another month by using the buttons in the title bar.

And as you can see in this screenshot, the Calendar also shows full moons that are in eclipse. If a full moon is a blue or supermoon, this will be indicated by a small badge on the day.

Data Page

For a deep dive into lunar details, open Moon Phase Pro's Data page, revealing full astronomical data about the moon (and even some about the sun). And it all updates automatically, in real time. There's lots more than you can see in this screenshot; as of version 8.0, this screen includes:

Additional data gets added to this page frequently; most major releases of the app include something new here.

Like the rest of the app, the Data page can easily be switched to show another day, or a different observer location anywhere on Earth. Want to know when the moon will rise on New Year's Day in Fiji? No problem.

Home Screen Features

Moon Phase Pro's functionality isn't limited to that within the app itself. This screenshot shows three of its features which can be added directly to your device's home screen.


Twenty-four hours before each major phase, Moon Phase Pro will notify you that it's about to happen with an icon like the one visible here at the upper-left. Expand the notification to see what's upcoming, including a preview image and the date & time of the event.


For the fastest access to moon imagery and details, Moon Phase Pro's home screen widget is your best bet. It's fully resizable, from a tiny 1x1 – the same size as a single shortcut, shown in the upper-left of this screen – all the way up to filling an entire home screen pane, if you wish.

All but the smallest size also have the option to display moon data, as seen on the medium-size instance at the lower-left here. Hide or show the data overlay by tapping the (x) button.

The widget layout is also adaptive: when you've sized it so that its width and height are roughly the same, the text will be overlaid on the image, as shown here. If you make it significantly wider than it is tall (or vice versa), the text will be shown alongside (or underneath) the image. It's up to you.

Live Wallpapers

Don't want to devote valuable home screen real estate to another widget? No problem – Moon Phase Pro comes with a live wallpaper, keeping an image of the current moon always in the background, in all its 3D glory. It's the same image shown in the main screen of the app, with the same options.

Lunar Eclipses

A big event for any moon enthusiast is a lunar eclipse, and of course, Moon Phase Pro has you covered here.

Be aware that lunar eclipse support is a work-in-progress: additional functionality is still being added, but some issues may also exist. Thanks for your patience while we finish this cutting-edge feature!

On the Big Screen

If you have a larger Android device, such as a tablet or Chromebook, you'll get even more out of Moon Phase Pro. The moon imagery itself is bigger and better, of course, but the layout is also optimized to make the most of the big screen.

On the Small Screen

Moon Phase Pro watch face on Wear OS

If you're rocking a Wear OS smartwatch, Moon Phase Pro has a couple of ways to bring its unique imagery and functionality to your wrist.

First, we've got a watch face, shown here. It features the same live moon graphic as our phone app, has a choice of analog or digital style, and supports up to 4 complications (to display information from other watch apps).

And speaking of complications, Moon Phase Pro is also a complication provider for other watch faces. Data available include the current phase – in text or icon format – as well as moon rise and set times. There's even "large image" provider that will put our trademark live-moon image in the background of any watch face that supports this feature.

Note: the Wear OS app is included in the purchase of Moon Phase Pro, but must be installed separately onto your watch.
