Purchase & Download

My payment was accepted but I can’t download the app. What should I do?

We receive a lot of support inquiries about purchase and download problems, but unfortunately, there’s very little we can do about it. The individual stores selling the apps are responsible for everything relating to purchase and download, and until the app is installed on your device, you’re in their hands.

Having said that, we’re happy to offer what advice we can:

Google Play Store
Other App Stores

If you’re having problems purchasing or downloading from any other retailer, then that’s who you need to contact in trying to resolve those problems. Links to the major stores selling Moon Phase Pro can be found on our Download page.

I had Moon Phase Pro on my old phone - how do I load it onto my new one?

Go to the market or app store that you bought the app from originally. Sign in with the same user ID that you used for the original purchase and you should be able to re-download the app without paying for it again. If this doesn't work, you'll need to contact the particular market in question for support.

I purchased the app with a different store account than I'm using now. Can I transfer it?

Unfortunately, none of the app stores provide a way for us to transfer app purchases from one account to another.

If you purchased it through Google Play, the best way to handle this is for you to purchase the app again, send us both the original and new order numbers, and we will then refund the original order – leaving the new order linked to your new account. It sounds like a hassle, but it does work out best in the long run.

If you purchased the app elsewhere such as Amazon then I'm afraid we have even less control over purchases and accounts. Your best bet is to contact customer service for the store in question and ask them to transfer it for you.

Widgets

How do I find the widgets?

To place a widget on your home screen:

Android 3.0 (Honeycomb) and earlier
Long-press in the area of the screen where you'll want it to be, then select Widgets > Moon Phase (in the size that you want)
Android 4.0 (Ice Cream Sandwich)
Open the app tray to the Widgets tab and select Moon Phase. There's a tiny 1x1 widget available, or a larger, resizable version that you can make any size from 2x2 on up. To resize the latter after it's on your screen, long-press it and drag the blue "handles".
Android 4.1 (Jelly Bean) and later
The resizable widget can be made any size, so there's no dedicated 1x1. Otherwise, the instructions are the same as for 4.0 above.

My widgets aren't working, though I can still open the app itself. What should I do?

The most likely cause is that your phone has moved the app to SD card; this disables all features outside the main app. From your phone's home screen, press Menu > Settings > Applications > Manage Applications > Moon Phase Pro. If there's a button there that says "Move to phone" that means that the app is on the SD card; press that button to move it off the SD card and back to the phone's main storage.

Here's what you need to do: From your home screen, press Menu > Settings > Applications > Manage applications > Moon Phase Pro. In the Storage section of the window that opens, if the right-hand button says "Move to phone", that means the app is on SD - which will disable the wallpaper. Tap that button, the app moves off of SD, and the widgets should be available again.

My phone upgraded to Android 4.1, and now I can't find your 1x1 widget. Where'd it go?

The widgets on recent Android versions are resizable; the default, initial size is 2x2, but you can make it any size you like. To resize, long-press on the widget until a box with blue "handles" appears around it, then drag those handles to change the size.

Although my phone is running Android 4+, I can't resize the widgets. What can I do?

Some device manufacturers (notoriously Samsung) use their own home screens, rather than complying with Android standards. As a result, third-party widgets (like ours) aren't resizable on some of these phones. You can read about the problem at androidcentral and reddit

A suggestion from the second link above is to replace the manufacturer's stock home screen with one that's Android 4 compliant, like Nova Launcher or Apex Launcher and we have had some reports of success with this approach from users.

There seems to be a visual bug with the widget. Any suggestions?

That seems to happen very occasionally when the cache gets corrupted. You could try just deleting and re-adding the widget; if that doesn't help, uninstalling and reinstalling the app definitely should.

The medium widget is not working properly. It will make the open and close sounds but won't always show information or only part of it. How can I fix this?

It's possible that you may have gotten a corrupted install. We'd recommend uninstalling the app, rebooting your phone, then reinstalling it.

Wallpaper

My live wallpaper isn’t working, though I can still open the app itself. Suggestions?

The most likely cause is that your phone has moved the app to SD card; this disables all features outside the main app. From your phone's home screen, press Menu > Settings > Applications > Manage Applications > Moon Phase Pro. If there's a button there that says "Move to phone" that means that the app is on the SD card; press that button to move it off the SD card and back to the phone's main storage.

When I’m using the live wallpaper, why can't I center the moon on any screen?

By default, Moon Phase Pro's wallpaper slides the moon image from side to side as you change home screens. You can turn that behavior off by pressing the Menu button in Launcher Pro (the three little dots at the lower-right), then Wallpaper > Configure and uncheck Slide.

If I set Live Wallpaper to the app, the tablet becomes very unresponsive, almost locked up. Is there a solution?

Have you tried turning off the "Dynamic surface shadows" option? It's in the main Moon Phase Pro app, under Settings.

Calendar

In the month view, can Monday be made the first day of the week?

Rather than having an option for this, the app uses the prevailing convention for the locale that the device is set for. So if your phone/tablet is set to UK (for example), Moon Phase Pro will show Monday as the first day of the week, as that's the prevailing custom there. If set to USA, it'll show Sunday.

I find it difficult to go up or down just one day. I'm swiping left and right. Am I doing something wrong?

Swiping is fun, but it's not the most precise way to move to a specific time or day. When you swipe, the app keeps the shadow synchronized with your finger movements, and this means that small movements translate into large date/time changes.

To go to a specific date, we'd recommend the Calendar (just tap on a day), or the Date/Time dialog (which also lets you enter a specific time).

Why does the image of the moon rotate when I select a different day on the calendar?

By necessity, the app isn't just showing you how the moon looks on a particular day, but also at a specific time on that day. Generally, the calendar depicts how the moon looks at the same time on each day; for example, if it's 7:30 PM when you open the calendar, it'll show the moon at it is appears at 7:30 PM on each day of the month. And the nature of the moon's orbit is such that it appears at a different point in the sky at 7:30 PM - and this means that its apparent rotation is also different for each day.

Essentially, it's the same reason that the moon image rotates when you change the time by swiping your finger over it. It's just that the calendar shows you a month's worth of dates (and times) all at once.

Why doesn't the moon image for first and last quarters match what's shown on the calendar?

Generally, the calendar depicts how the moon looks at the same time on each day, and this holds true for every day except major phase (new, full, and quarters). Because these phases occur at specific times (not just on a particular day), the app needs to show you the moon for those times, or the moon wouldn't be in the correct phase.

Extending the example from the previous answer, the calendar may be showing you most days for 7:30 PM. However, the First Quarter moon probably doesn't occur at 7:30 PM, but at a completely different time - let's say 5:42 AM. So when you tap on the First Quarter day on the calendar, the app will show you the moon as of 5:42 AM on that day, which is almost certainly a different rotation than 7:30 PM.

Miscellaneaous

What do the terms used on the Data page mean?

Visible disc
Simply, how much of the moon's surface (as viewed from Earth) appears illuminated by sunlight.
Phase
The moon's appearance has a (roughly) 29-day cycle during which it goes from fully dark to fully illuminated and back again. The following four terms are used to describe where in the cycle the moon is.
Waxing
The first half of the cycle, when the illuminated portion of the moon is increasing. In other words, a waxing moon appears larger tonight than it did last night.
Waning
The second half of the cycle, when the illuminated portion of the moon is decreasing.
Crescent
A moon that is less than half illuminated (<50% visible disc)
Gibbous
A moon that is more than half illuminated (>50% visible disc)
Age
How far through the moon's cycle it is, measured from the moment of new moon. The average lunar cycle is 29 days 12 hours 44 minutes long, but it varies from month to month.
New Moon
The point in the moon's cycle when it is completely dark.
Full Moon
The point in the moon's cycle when it is completely lit. Colluquially, full moon is used whenever the moon is close enough to this point to appear completely round, but astronomically, it refers to a single instant when the moon is at its farthest from the sun.
Altitude
How far above (or below) the horizon the center of the moon's (or sun's) disc appears from your location. Note that the horizon here is idealized as being perfectly flat and level.
Azimuth
The moon's (or sun's) compass bearing as seen from your location.
Right ascension
The "x-axis" angular coordinate of the moon in the sky, measured eastward from the vernal equinox. This is the astronomical equivalent of longitude.
Declination
The "y-axis" angular coordinate of the moon in the sky, measured northward from the celestial equator. This is the astronomical equivalent of latitude.
Distance (centroid)
The current distance from the center of the earth to the center of the Moon.
Mean orbital radius
The average centroid distance as the moon goes around the earth, which is 384,399 km or 238,854 miles.
Perigee
The closest approach of the moon to Earth in its orbit (363,295 km = 225,741 miles).
Apogee
The furthest remove of the moon from Earth in its orbit (405,503 km = 251,968 miles).
Rise
The time when the top of the moon's (or sun's) disc appears above an ideal horizon, as seen from your location. Compass bearing (azimuth) is also shown.
Set
The time when the top of the moon's (or sun's) disc disappears below an ideal horizon, as seen from your location. Compass bearing (azimuth) is also shown.
Zenith (or Transit)
The time when the moon (or sun) is at its highest point above the horizon.
Nadir (or Antitransit)
The time when the moon (or sun) is at its lowest point below the horizon.
Dawn and Dusk
Put simply, these two times are the end and beginning (respectively) of full darkness. However, there are a number of ways to define "darkness"; by default, Moon Phase Pro uses nautical twilight, the time when the sun is 12 degrees below horizontal. You can change this to civil twilight (-6°) or astronimical twilight (-18°) under Settings > Dawn and dusk;

Occasionally the azimuth for lunar zenith is 179 instead of 180. Why is that?

Basically, it's due to the slight "wobble" of the earth's rotation on its axis. It's the same mechanism that produces the earth's analemma. See the explanation on Wikipedia.

Will the app power on my GPS if I have it switched off?

No, the app won't power on your GPS if you've turned it off at the device level. No app can do that unless you've rooted your device, and even then, Moon Phase Pro won't.

What are the permissions that Moon Phase Pro is asking for and why?

Here's a list of the permissions that Moon Phase Pro requests, along with a brief description of each. Click on any of them for a detailed explanation.

YOUR LOCATION: COARSE (NETWORK-BASED) and FINE (GPS)
Moon rise and set times depend on where you are
FULL INTERNET ACCESS
To look up locations, and to download the imagery used for Dynamic Surface Shadows
MODIFY/DELETE USB STORAGE or SD CARD CONTENTS
To store various images for faster operation
START AT BOOT, SET WALLPAPER
Both essential to making the live wallpaper work (Android 1.x and 2.x only)

Does Moon Phase Pro give tide times?

No, it doesn't.

Although tides are intrinsically linked to the moon's (and sun's) gravitational pull, accurate tide times involve much more, being greatly influenced by the configuration of local waterways. As such, adding tides to Moon Phase Pro would greatly increase the size and complexity of the app; for example, just including the tide tables would make the app several megabytes larger. We believe that smartphone apps should be specialists, that they should "do one thing and do it well."

In that vein, there are some fairly reasonable tide apps already available for Android; we recommend TideApp and Tide Predictor, they're the ones we use.

What does "View is rotated -31 deg from Earth" actually mean?

You'll see text like this when rotating the view off-Earth using two-finger drag (only available on devices with Android 2.2 (Froyo) or later). The simulation keeps the view centered on the moon, but the observer's viewpoint is no longer on the Earth, and the number of degrees simply indicates how far away from the earth the viewpoint has moved. Positive numbers indicate a viewpoint moved in the direction of the Moon's orbit, while negative numbers are moved opposite to the Moon's orbit.

What versions of Android does the app work on?

Version 2.1 (Eclair) through the latest version, which is 4.4 (KitKat) as of this writing. When newer versions are released rest assured that the app will be updated to work on those too. Updating this web page is a lower priority than making the app work, however, so don't be concerned if it lags a bit behind.

Why has the moon turned yellow on my phone?

Happy April Fool's Day! A bit of a cheesy joke but one that keeps us Wisconsinites amused. It will be back to its normal appearance on the 2nd.
