LunadotTonight's moon and the next full moon date, at a glance
No sign-up, no internet needed. No ads covering the moon.
Moon app reviews keep repeating the same complaints: too many ads covering the moon, a countdown to the full moon with no actual date, and apps that can't find your location or show the wrong day's moon. Lunadot computes everything on your phone so it works offline, shows the next full moon as a date, weekday and D-day, and only uses an approximate location once if you want moonrise and moonset.
Why people delete moon apps
"Too many ads cover the moon" — you close three pop-ups to see one moon
"It only says how many days until the full moon — give us a date too"
"Can't find my city", "shows the moon phase for the wrong day"
Just simple. Tonight's moon, and the next full moon. 🌕

Frequently asked questions
Do ads cover the moon?
No. The app is free and shows ads, but they are placed so they never cover the moon or the phase details.
Is there a moon phase widget?
Yes. The home screen widget shows tonight's moon and the next full moon without opening the app.
Does it only tell me how many days until the full moon?
No. The next full moon, new moon, first quarter and last quarter are shown with date, weekday and D-day.
What if it can't detect my location or find my city?
Phase, illumination, moon age and upcoming phases need no location at all. Location is used only for moonrise and moonset: an approximate location is taken once and stored only on your device, so there is no city search to fail.
Could it show the moon phase for the wrong day?
It computes the moon on the device from your phone's current date and time zone, so you see tonight's moon. Phase times match published times within minutes.
Does it work offline?
Yes. All calculations happen on the device, so no internet connection is needed.
Do I need an account?
No. Install it, open it, and tonight's moon is there.
I just want a simple app. Is this it?
That is the idea. The first screen is tonight's moon and the next phase dates; the calendar, reminders and widget are there when you want them.
