If you're like us, you don't like reading dates and numbers from a table and then try to figure out how many days you have until the next new or full moon. Perpetuum solves this problem and gives you the information you need in a way we couldn't find anywhere else.



Spinning the moon clockwise will get you forward it time, while backwards goes back.



▶ New Moon is UP

▶ First Quarter is on the RIGHT

▶ Full Moon is DOWN

▶ Last Quarter on the LEFT





▶ No internet connection required.

▶ Ability to set a marker to a certain moon phase (your birth date for example)

▶ To change the date, drag the moon or tap the date.

▶ Weekend days are drawn brighter so you can instantly see which day of the week a certain moon phase will be in.

▶ Shake the phone/ipod to return to the current date.



You'll definitively get addicted to it after getting a taste of it's power.



Many lunar calendars assume the lunar cycle length is constant (or better said they are using the mean length of 29.53 days). Unlike those calendars, Perpetuum calculates the precise moment for all the moon phases.

Useful & fun

I've been an amateur astronomer for almost 40 years and used handheld moonphase apps on the Palm, iPhone and other platforms. This one actually makes it fun to look up what the phase will be for an observing night - and looking up future dates is very fast. Weeks or months away can be quickly accessed by tapping on the date on the main screen which brings up a m/d/y selector. What can be added to make it even better? It would be nice to have data on the bottom of the screen with lunar info such as luminosity, distance, etc. Coolest moon app for the iPhone & touch.

The Best One!

I have tried all the other moon apps and all had way too much info than what I needed. I like this app cuz it pertains to the moon cycle only and very easy to use. Like how you can scroll in a circle to find the moon phases. Tried the free lite version for a couple minutes before buying this. It's worth it. Very stable and smooth scrolling, etc. Very well thought out application. Nice work Vlad and Ade!

Needs Updating Please!

This is by far the best moon phase app. Simple, user friendly, and contains all the information you need. The only thing it lacks is an update to be compatible with later iOS versions. Could the developers please update it? Thank you!
