What this is

An iPhone weather app that tries to be right for reasons you can inspect.

Most weather apps pick a model and show you its output. Some average a few of them. WeatherMeld does something more careful: every forecast is the product of a methodology we've been building and validating against years of real observations, and the app lets you see how the answer was reached when you want to.

Tap a number and you see the reasoning. Tap the reasoning and you see the underlying data. Most users will never do either, and that's fine. The answer on the first screen is the same either way.

Coverage

Continental US only. Alaska, Hawaii, and US territories aren't supported — the methodology isn't tuned for those regions, and serving them would mean serving them poorly.

Full CONUS from launch. Open the app in Nashville or Missoula or Green Bay and it works.

More than the forecast

Weather is more than just temperature and rain. The app carries the rest — one place for the whole picture — and, for people whose plans live closer to the water, the snow, or the sky, layers that go deeper than others.

Some of those numbers aren't ours — air quality readings, for example, come from federal monitoring networks. Anything we pass through shows its issuer and issue time: the same tap-to-inspect rule, applied to work that isn't ours.

What it won't do

WeatherMeld does not produce its own severe weather forecasts. Warnings for dangerous conditions come from the National Weather Service, passed through unaltered and clearly attributed. When lives are at stake, the answer should come from the people whose job that is — not from an app trying to differentiate itself.

Feels-like temperature

Feels-like is shown as a short qualitative banner — feels cooler, feels about right, feels much hotter — with safety flags at extremes. It isn't a specific number because it isn't one. Apparent temperature is a modeled estimate with real uncertainty; displaying it as 42°F implies a measurement precision that doesn't exist. Tap the banner to see the estimated range.

Free and paid

The free tier is a complete weather app, not a demo. No ads, no selling your data, no nagging you to upgrade. If it scratches your itch, use it forever — free.

The paid tier exists for people who want more — deeper layers, more places, more on the home screen. It's expansion, not ransom. Details closer to launch.
