About El Niño
El Niño is an iOS application designed to help users track live signals from the Pacific warming climate. Developed by GIS expert Tony Expert, the app translates complex public NOAA data into a simple, straightforward answer: whether the tropical Pacific warming signal is building, fading, or remains uncertain.
Instead of acting as an official forecast or guidance, El Niño provides independent context by showing what has changed, where the warm water sits, and how similar historical events unfolded in the past. Designed for weather enthusiasts and data-conscious users alike, the app includes a Home Screen widget to keep the latest complete updates close at hand.
The app operates on a transparent, upfront one-time purchase model with no mandatory accounts, ongoing subscriptions, or recurring fees.
