## Overview

NimbusWx is a spot weather forecasting app for iPhone that makes professional-grade numerical weather prediction data accessible. Most weather apps hand you a finished icon and a temperature; NimbusWx instead visualizes the raw output of the numeric models that industry experts actually use, turning data that normally requires desktop software into friendly, zoomable charts.

Where it stands apart is its AI layer. Since version 1.2 the app has included a customizable AI weather forecaster powered by ChatGPT. You control what type of weather data you care about and how the forecaster behaves, then use prompts such as asking about wildfire risk or skiing conditions, or even asking it to speak in a particular style. A 2025 update brought improved AI summaries and search for locations.

The app draws its data from SpotWx, a forecasting site used by professionals across North America and beyond. It supports the GFS, RDPS, HRDPS Continental, HRDPS 1km West, GDPS, NAM, HRRR and RAP models, letting you compare them for the same coordinates and inspect each model's simulated altitude and resolution before trusting its output.

## Pricing & Plans

NimbusWx is free to download with optional in-app purchases for the pro tier via the App Store. Check the App Store listing for current pricing.
