Name: Hiyori - Outdoor Conditions
Author: finack

A one-glance rating of outdoor conditions right now: Good, Fair or Poor for your current location, plus the single factor holding the rating back and when conditions next improve.

Apparent temperature, rain, wind, UV, air quality and pollen are combined into one score, rated against the activity you pick — general, run, bike, hike or allergy. Humidity is displayed as context but does not affect the verdict. The same hour rates differently for a ride than for a walk.

Rate it your way: all three category names can be changed in settings.

Air quality follows the European or US AQI scale, UV the WHO index, pollen normalised per species. Data from Open-Meteo (CC BY 4.0), including Copernicus CAMS data. Global coverage, no account, no API key, no backend, no tracking.

Hiyori summarises publicly available forecast data for general interest. It does not monitor conditions, raise alerts, or recommend a course of action, and forecasts are frequently inaccurate. Any decision about going outdoors is your own.
