What This Moon App Actually Offers
Phases of the Moon is a free Android app from M2Catalyst built for anyone who wants a quick, visual way to track lunar phases. It centers on a 3-D moon simulation built from NASA imagery that you can spin and pinch-zoom to explore craters, mare, and landing sites. Beyond the visuals, it packs in moonrise/moonset times, illumination percentage, distance to the moon, astrology zodiac sign data, a monthly lunar calendar, and hunting/fishing forecasts, making it as much a reference tool as a novelty app.
Where It Shines in Daily Use
The standout feature by far is the home screen widget, which lets users check the current moon phase without opening the app at all – several long-time users specifically call this out as the reason they’ve stuck with it for years. The 3-D simulation itself is genuinely well done, with reviewers praising the smooth drag-to-spin interaction and the level of detail in the lunar atlas. One reviewer with 64 ‘useful’ votes called it a ‘brilliant app that does exactly what I want,’ highlighting the lack of intrusive ads and the option to pay once to support the developers rather than being pushed into a subscription.
Notifications and Stability Issues That Frustrate Users
The most common complaint in real reviews is unwanted notifications. Multiple users report the app suddenly began sending frequent, intrusive alerts about moon events with no opt-in or way to disable them, which several people found to be a dealbreaker after years of otherwise happy use. There are also recurring technical problems: one user on a Galaxy S10+ said the app opens for a split second and crashes immediately, even after reinstalling. Others mention a persistent libration error where the simulated moon nods incorrectly, and a compass calibration bug where the moon’s orientation doesn’t update as you physically rotate the phone.
Smaller Annoyances Worth Knowing About
A few users reported a red warning icon appearing unexpectedly on top of the home screen widget with no clear way to remove it, forcing them to pull the widget off their home screen entirely. Combined with the notification issues, this suggests the app has had some rocky updates that introduced bugs into features that previously worked fine, which is especially frustrating for users who relied on the widget as their main touchpoint with the app.
Who Should Download Phases of the Moon
If you want a free, visually rich moon-tracking app with a genuinely useful home screen widget and don’t mind occasionally digging through settings to tame notifications, this app delivers real value, especially for hunters, anglers, and astrology-curious users who want lunar data in one place. But if you’ve been burned before by apps that quietly change permissions or notification behavior, or if you’re on certain devices like newer Galaxy phones where crash reports have surfaced, go in aware that stability has been inconsistent in recent versions. It’s a solid pick for casual moon watchers, less so for anyone who needs rock-solid reliability every single day.
