Moon Lunation shows you the Moon's phase for any date between 2000 and 2050 — computed on your device, from the actual geometry of the Sun, Earth and Moon. No connection. No account. No data collected. COMPLETELY REBUILT The original 2009 version read its phase times from a fixed table and estimated the dates in between. This version solves the geometry directly, so every phase name, illuminated percentage, lunar age and event time is calculated for the exact moment you ask about. The results are checked against NASA JPL's DE440 planetary ephemeris — the same reference used for spacecraft navigation. TODAY The current phase, the illuminated percentage, how far through the lunation you are, and when the next principal event falls in your local time. CALENDAR Any month from January 2000 to December 2050. New moons, first quarters, full moons and last quarters are marked on the local dates they actually occur. Tap any day to see its phase. CYCLE Watch a single lunation play out from one new moon to the next. The timeline runs between two actual computed new moons, so its length varies from cycle to cycle — it is not forced to the average of 29.5 days. Scrub it with your finger, or play it through in fifteen seconds. THE MOON ITSELF The surface is built from Lunar Reconnaissance Orbiter imagery, reprojected into a fixed north-up view of the near side. The lit region is drawn from the computed phase, so what you see is the geometry, not an illustration of it. WHAT IT DOESN'T DO Being clear about the edges: • It covers 1 January 2000 to 31 December 2050. Outside that range it tells you so rather than guessing. • It is a north-up diagram of the phase, not a picture of how the Moon looks in your sky tonight. The real Moon appears rotated depending on where you are, and this app does not represent that rotation. • It does not show libration, the Moon's slight apparent wobble. • It does not predict eclipses. Phases come from changing Sun–Earth–Moon geometry, not from Earth's shadow — eclipses are separate events. • Times are geocentric, calculated for the Earth as a whole rather than for your location. There is no location feature and no city list. • It does not show moonrise or moonset. PRIVACY This app makes no network requests of any kind. There is no analytics, no crash reporting, no advertising, no tracking, and no account system. It does not ask for your location. It stores no personal data and writes nothing about you to disk. It works in Airplane Mode, on the first launch and every launch after. iPhone and iPad. Requires iOS 17 or later. Lunar surface imagery courtesy of NASA's Scientific Visualization Studio. NASA does not endorse this app. ## Key features - Offline moon phase computation - Date range 2000-2050 - Illuminated percentage display - Lunar age and event times - Monthly calendar view - Lunation cycle visualization - 3D Moon surface model ## Chart rankings - #113 in Top Paid · Weather (US App Store) ## Recent user reviews (10 of 35) All indexed reviews: https://appshunter.io/ios/app/moon-lunation/id312811399/reviews.md ### 1/5 — Scam *2016-09-22* This app does not work ! Do not spend your money on this sh/t ### 1/5 — Old - should be removed *2016-05-14* This app doesn't function. It should be removed from the store. FYI, pay attention to version dates before downloading an app. I didn't. I would have given zero stars, but you can't. ### 1/5 — Moon cal. *2016-03-08* Doesn't work, please don't waste your money. ### 1/5 — ??? *2014-10-08* This app doesn't work! Was very excited as I wanted a moon calender spread just like this but it only shows one moon on 1st of October and the rest is blank. Really cheesed off ### 1/5 — Moon lovers *2013-09-20* Pretty Simple. It doesn't even say what type if moon it is. Example: full moon or new moon: It's just a picture with the moon lite and you figure. no many options in apps for moon lovers :( ### 4/5 — Exactly what I was looking for! *2012-09-16* All the other apps where too fancy or didn't give the exact enough image phases, more percentiles than visuals. The only thing I'd change is to be able to change the date by typing rather tan hitting an arrow and waiting. If I want to see a different year it takes some time to get there. ### 1/5 — Schrott *2011-08-28* In den Einstellungen fehlen viele Länder, u. a. Deutschland. Man kann auch nicht Orte selbst anlegen. Bei mir stürzt die app ab (reproduzierbar) wenn ich im Kalender 2x schnell auf "weiter" tippe. App mit Bugs und ohne Mehrwert, für mich rausgeworfenes Geld ### 1/5 — Rip-off! *2011-08-24* I hope you read the comments prior to purchasing this app, unlike me. It does not function, it is simply a shell app created to take your money. Apple! How can you let this continue? ### 1/5 — Don't buy- it doesn't work! *2011-06-02* Wish I'd read the reviews first, this app has never worked! ### 1/5 — Disfonctionnement *2011-05-31* Aucun calendrier lunaire n'apparaît, c'est honteux. ## Frequently asked questions about Moon Lunation ### What is Moon Lunation? Moon Lunation is a paid application that displays detailed moon phase information for any date between 2000 and 2050. It computes phases offline using precise astronomical geometry and offers features like a lunar calendar and a 3D model of the Moon's surface. ### Does Moon Lunation work offline? Yes, Moon Lunation is designed to work completely offline. It makes no network requests, meaning it functions even in Airplane Mode and does not collect any user data. ### What is the price of Moon Lunation? Moon Lunation is a paid app priced at $0.99. This one-time purchase grants access to all its features without any additional costs or subscriptions. ### What devices is Moon Lunation available on? Moon Lunation is available for iPhone and iPad devices. It requires iOS 17 or later to run. ### How accurate are Moon Lunation's calculations? The app's calculations are checked against NASA JPL's DE440 planetary ephemeris, which is the same reference used for spacecraft navigation, ensuring high accuracy for phase names, illuminated percentages, and event times. ### Does Moon Lunation show eclipses? No, Moon Lunation does not predict eclipses. While it calculates phases based on Sun-Earth-Moon geometry, eclipses are separate events related to Earth's shadow and are not included in this app's functionality. ### How often is Moon Lunation updated? The latest version, 4.0, was last updated on September 14, 2026. While specific update frequency isn't detailed, the app's core functionality is based on stable astronomical calculations. ### What do users think of Moon Lunation?

This suggests a very limited user base or potential for improvement in user satisfaction. ## Version history (last 5 releases) ### 4.0 — 2026-09-14 Version 4.0 - the app has been rebuilt from scratch. If you owned the original Lunation, this is a different app under the same name. Please read the two changes below before updating. PHASE TIMES ARE NOW COMPUTED The old version read its phase times from a fixed table covering 1996 to 2010, and estimated the dates in between. That table ran out years ago. This version calculates the Moon's position directly, from the geometry of the Sun, Earth and Moon, for any date from 1 January 2000 to 31 December 2050. The results are checked against NASA JPL's DE440 planetary ephemeris. THE CITY LIST HAS BEEN REMOVED The old version let you pick a city. That feature is gone, and so is location access entirely - the app no longer asks for your location and makes no network requests of any kind. ne 9:53 PM What's new in this version The old version let you pick a city. That feature is gone, and so is location access entirely - the app no longer asks for your location and makes no network requests of any kind. Event times are now shown in your device's own time zone, and are calculated for the Earth as a whole rather than for a specific place. ALSO NEW • A real lunar surface, built from Lunar Reconnaissance Orbiter imagery • A Cycle view that plays a full lunation from one new moon to the next, with a timeline you can scrub • A calendar marking every new moon, first quarter, full moon and last quarter on the local date it occurs • Native iPad support • Nothing is collected, stored or transmitted — it works entirely in Airplane Mode Requires iOS 17 or later.
