Can an iPhone app make El Niño useful beyond weather headlines?

I ve been building El Ni o, a native iPhone app that turns live NOAA climate data into a clear view of what is happening across the tropical Pacific.

Instead of showing only an El Ni o or La Ni a label, the app explains the current signal, its strength and direction, confidence, key drivers and similar periods from the historical record. It is designed for people following climate, agriculture, energy, commodities and insurance who want to understand the evidence without digging through scientific reports and raw datasets.

El Niño - See live signals from the Pacific warming climate

El Niño is a recurring warming pattern in the tropical Pacific that can influence weather around the world. This iPhone app turns live public NOAA data into a simple answer: is that warming signal building, fading or still uncertain? See what changed, where the warm water sits and how similar events unfolded before. A Home Screen widget keeps the latest complete update nearby. Upfront paid once, with no account or subscription. Independent context, not a forecast or official guidance.

Do you really need QGIS just to check what's inside a file?

I noticed I was opening full GIS software dozens of times a day just to answer:

"what's in this GeoJSON?"
