Is the Moon Worth Looking Up Tonight? | Selene
Frequently asked questions
- What does Selene actually tell me?
- One line: worth a look tonight, or hidden by clouds. It fuses phase, position and sky conditions into a single honest call rather than a percentage readout.
- What happens when Selene does not know?
- It says so instead of faking certainty.
- How does it know the sky conditions?
- All astronomy runs on device, with WeatherKit supplying hourly cloud cover.
- Do I need an account?
- No. No account and no tracking — your sky stays yours.
The short answer
Moon-phase apps give you a table. A table does not answer the only question you actually have, which is: is tonight worth going outside for?
Selene answers that instead. It gives you tonight's phase, position and sky conditions fused into one honest call — "worth a look tonight" or "hidden by clouds".
Not a percentage readout
The design decision here is what it refuses to be. Instead of a number to interpret, you get a line. Most people looking at the moon do not want a phase percentage; they want to know whether to put on shoes.
When it does not know
Worth stating plainly, because apps that synthesise certainty are the ones to distrust here: when Selene can't know, it says so rather than faking certainty.
An honest "I don't know" is more useful than a confident number, because it tells you the difference between "there are clouds" and "I have no weather data for your location".
Find it in seconds
Point your phone at the sky and the AR overlay shows exactly where the moon is right now — even before it rises.
That last clause is the useful part. The question is rarely "where is the moon tonight" but "which way do I walk", and an answer that only works after moonrise does not answer it.
