Weather learning that stays with you, not with us.
Aether is the forecasting layer inside UndercastWeather. It processes weather signals on device, keeps its learning on device, and gives people control over how much Aether is involved. No ads. No remote profile built around your weather habits.
That is the core idea behind the feature. The goal is a weather assistant that adapts without shipping your habits off to build an ad product.
Some people want the extra forecasting layer all the time. Others only want it when conditions are changing. Aether is designed to respect that difference.
The intent is continuity between iPhone, CarPlay*, and Mac without turning that sync into a public profile or a sales channel.
Aether is designed to improve how forecast information is presented and controlled within UndercastWeather, while keeping user choice front and center.
iPhone
Aether lives close to the current conditions, alerts, and hourly changes so the app stays quick to read. The point is less noise, not more.
- Current conditions and hourly changes stay first
- Aether can add context without taking over the screen
- Designed for people who check weather many times a day
*CarPlay
CarPlay, subject to entitlement approval, keeps only the next important weather decision in front of you, with as little distraction as possible.
- Weather alerts stay glanceable
- Timing changes matter more than decorative detail
- No ad clutter competing for attention
macOS
On the Mac, Aether has room for longer-range reads, side-by-side views, and the settings people actually want.
- Extended forecasting generated on device
- More room for controls and comparison
- A clear place to manage Aether behavior
