Quick verdict
If you want to follow the Moon, or the Sun and planets, Daff Moon Phase gives you a lot for free: many reviewers praise how much information it has and how easy it is to use, and several have kept it for years. Several also say they donated. On the downside, several reviewers saw wrong rise and set times, which the developer’s replies usually trace to the wrong location or time zone, and several found the zodiac sign wrong for astrology; the developer’s replies point to the sidereal zodiac setting. Several say notifications or widgets don’t update reliably on their phone. It is an astronomy app, not a forecast app: the listing doesn’t mention weather.

What is Daff Moon Phase?
Daff Moon Phase is an astronomy app for the Moon, the Sun and the planets. It calculates the Moon’s phase and age, shows a phase calendar for any month, and gives rise, set and transit times, altitude and azimuth for the Moon, the Sun and the planets from Mercury to Pluto. Everything is calculated from your location and the moment you pick, the listing says. A sky sphere you can rotate shows where everything is. It has been on Google Play since September 2012.
Key features
- Moon: current phase and age, node passages, a phase calendar and a rise and set calendar for any month, and a supermoon calendar for any year.
- Sun and planets: day length, rise, set and transit times, zodiac signs, altitude and azimuth for the Sun and the planets, plus planetary orbits and motion.
- Events: lunar and solar eclipses with visualizations, solstices and equinoxes.
- Sky sphere: an interactive sphere with the positions of the Moon, the Sun and eight major planets.
- Photography times: golden and blue hours for each day.
- Widgets and wallpaper: 7 home screen widgets and a live wallpaper with the current Moon phase.
- Notifications: customizable alerts for events such as sunrise and full moon.
Daff Moon Phase vs. what a weather app should have
“Listed” means the Google Play listing names the feature, “Partial” means it covers part of it, and “Reviews only” or “Reviews and developer replies” means we found it outside the listing. Daff Moon Phase is filed under weather but is an astronomy app, so the forecast rows don’t apply; it fills the sun, moon and photography rows.

Common problems and fixes
The sample goes back to 2014, so older reports may describe earlier versions, and menu names may differ by version.
| Problem | What reviewers report | When | What the developer’s replies suggest |
|---|---|---|---|
| Rise and set times are wrong | Several reviewers, for example a moonrise 4 hours off or sunrise and sunset far from local times | 2020 to December 2025 | The usual causes are wrong geographic coordinates or a wrong time zone (July 2021); a wrong time zone can also cause wrong results, so send a screenshot of the main window and your city to [email protected] (December 2025) |
| Wrong location or city | One reviewer couldn’t change the city | June 2025 | Go to Settings, then Location, and enter coordinates or pick a place on the map (June 2025) |
| Zodiac sign doesn’t match astrology sources | Several reviewers | 2021 to October 2025 | Turn on the sidereal zodiac option in Settings (2021). A 2025 reply says it is an astronomical app, not an astrological one |
| Notifications or alarms don’t arrive | Several reviewers, one in April 2026 even after setting battery use to unrestricted | 2016 to April 2026 | Another antivirus or optimization app may be blocking them (2017) |
| Can’t find the monthly calendar or the next full moon | Two reviewers | 2024 | Tap the ≡ menu at the top left and choose Phases (June and November 2024) |
| Widgets don’t appear, get clipped or don’t update | Several reviewers; two say widgets don’t update reliably, on a Motorola Razr 2023 and after a One UI 7 update | 2021 to July 2025 | Phone makers’ power-saving modes can stop widgets updating; work is under way to update them more regularly (May and July 2025) |

Of the ratings in the store’s rating breakdown, 1.5% are 1 or 2 stars and 91.8% are 5-star. The review sample deliberately includes extra low-star reviews, so complaints show up more in it than in the ratings.

Pricing
Daff Moon Phase is free, and Google Play lists no ads. In-app purchases run from $0.99 to $99.99 per item, but the listing doesn’t say what they are. Several reviewers describe donating to the developer, and two mention a basic version, one of them saving up for the upgrade. In September 2026 a reviewer asked about ad traffic; the developer replied that all ads were removed a couple of months earlier and the latest version has none.
Privacy and permissions
We couldn’t read the Google Play data safety section, so we make no claim about what it declares. The listing says all calculations use your location and the selected time. The permissions list includes approximate location (network-based), control vibration, full network access, precise location (GPS and network-based), prevent device from sleeping, read the contents of your USB storage, run at startup, set wallpaper and view network connections. One reviewer in August 2026 calls the permissions minimal; one in June 2025 uninstalled over privacy concerns, citing the app’s Yandex and Google APIs.
Who it’s for
Daff Moon Phase suits you if you follow moon phases, rise and set times, eclipses or planet positions, whether for photography, gardening, astrology or a telescope, and you want widgets and a Moon wallpaper without paying. Set your location and time zone carefully. Skip it if you want weather forecasts, or if you need event notifications you can count on without testing them on your phone first.
FAQ
Why are Daff Moon Phase rise and set times wrong?
A 2021 developer reply says the usual causes are wrong geographic coordinates or a wrong time zone, and a 2025 reply adds that a wrong time zone can lead to wrong results. You can set your location in Settings, then Location, by entering coordinates or picking a place on the map. If times are still off, the developer asks for a screenshot at [email protected].
Why is the zodiac sign different from my astrology app?
A 2021 developer reply suggests turning on the sidereal zodiac option in Settings. A 2025 reply adds that this is an astronomical app, not an astrological one, so it has little astrological information.
Does Daff Moon Phase have ads?
Google Play lists no ads, and several reviewers say it is ad-free. Developer replies from 2020 and 2021 say the app had no ads, one reviewer in 2023 says it then had ads, and a September 2026 developer reply says all ads were removed a couple of months earlier.
Does Daff Moon Phase show the weather?
No weather data is mentioned in the listing. It covers the Moon, the Sun and the planets, including golden and blue hours for photography. Use a weather app and official alerts for forecasts and warnings.
