About this app

Will tonight’s sunset actually be worth it? Helio tells you before you go.

Helio uses real weather and an ML model to rate how good every sunrise and sunset will be at your exact location — on a clear, simple scale. No more guessing whether to grab your camera or just step outside.

What you get:

• Sunrise & sunset quality scores — every day, at a glance, for your exact location

• Built-in weather — see the conditions that shape the sky before you head out

• Multi-day forecasts — plan shoots, hikes, and trips around the best skies ahead

• Community Reports — real sky conditions from people near you, live on a map. Rate your own sunset to help everyone call the next one

• Top Predicted Spots — discover the places worldwide our model expects to have a genuinely great sky tonight (only the standouts make the list)

• Clean, fast design — the answer you need, none of the clutter…

Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app package we scanned

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
