How to Plan a Moon-Watching Night With an iPhone

Selene combines moon phase, rise and set, altitude, your horizon and weather into a plain-language verdict, then points you toward the moon with an AR overlay.

The problem this product is built around

A moon calendar can tell you the phase and still fail to answer the practical question: will the moon be above my horizon when I can go outside, and will clouds make the plan pointless? A percentage looks precise while hiding those conditions. Planning needs a short verdict backed by the rules that produced it.

How Selene solves it

Selene checks cloud cover, moon altitude, local horizon and rare events with five fixed rules. When a weather source is unavailable it says that evidence is missing instead of turning silence into a clear night. The AR overlay then uses the device’s field of view and attitude to help you turn toward the moon. Open the Selene product page to see current availability and plan details.

A practical workflow

  1. Allow location so the rise, set and horizon are calculated for where you actually are.
  2. Read the one-line verdict and open the rule details if the answer seems surprising.
  3. Use the date scrubber to compare nearby nights, including the free two-week window around today.
  4. Go outside and use the AR overlay only as a direction aid; keep your eyes and surroundings in charge.

What to check before you trust the result

Selene cannot control clouds, buildings or the accuracy of the device sensors. A missing weather provider makes the verdict less complete, and AR direction is not a substitute for safe outdoor navigation. The sky is still the final authority.

Who this workflow is for

This is for casual observers who want to decide whether to look up tonight and where to start looking. It is not an observatory planning suite, a telescope controller or a weather guarantee.

Go deeper

The product page is the right place to start if you are deciding whether the workflow fits your problem. For detailed mechanics, read See the one-line verdict rules, and Use the AR finding view.

The useful promise of Selene is specific: it shortens one repeated decision while keeping evidence, assumptions and stopping points visible. Start with one real task, inspect the result, and only then make it part of your routine. Try Selene.
