About this app

Halcyon is a calm, honest weather app for iPhone, Apple Watch, and the Home Screen. It turns the forecast into one clear sentence — what's likely, what to plan around, what's safe to skip — instead of throwing dashboards at you.

— TODAY BRIEF

A short, plain-language summary of the next twelve hours: rain risk, UV, wind, and the comfort of being outside. Built from Apple Weather data, written like a friend who happens to read the chart.

— HEADS UP

A glanceable card surface with what actually matters: rain soon, strong wind, freeze risk, severe weather. Confidence is labelled when conditions are changing — Halcyon won't fake certainty.…

Store update history

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

App Store

Version 1.3.0 · 2026-10-03
See what changed overnight, keep rain timing on the Lock Screen when rain is on the way, and check U.S. air quality from AirNow. Tap any city in your locations list to jump straight to it, and the list now marks the city you're viewing. Also in this update: • Tap a location in the widget to open that city in the app • A short setup guide covering the widget, notifications, and Siri • Severe weather alerts now request notification permission on a fresh install • The widget refreshes when you add, remove, or reorder cities • Temperature units now apply to the history and year-ago strips • Metric units by default in the United Kingdom • Radar time labels read correctly on 24-hour clocks •…

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.
