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.

Could you build this?
Yes It pulls forecasts from public or low-cost sources (ECMWF open data, NOAA GFS, DWD ICON, UK Met Office DataHub) and applies a simple agreement or spread classifier. The work is data plumbing and a clear UI.
