Know when to trust the weather forecast
Your weather app shows one forecast, blended from several big computer models. When they agree, you can trust it. When they don’t, it’s closer to a coin toss, and you’d never know. Chorus compares ECMWF, the US GFS, Germany’s ICON and the UK Met Office and sums them up in one word: Agree, Mixed or Split, with a plain-English reason. Widgets show the verdict at a glance. Free for iPhone. Chorus Plus adds widgets, two extra models and 20 saved places, with a one-week free trial.
Chorus Weather aggregates forecasts from multiple models, indicating their consensus with terms like Agree, Mixed, or Split. The app is free for iPhone, with a premium version offering additional features and a one-week trial.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
