4. The Weather Channel

The most downloaded weather app globally. Detailed hourly and 10-day forecasts, radar, and severe weather alerts. The app is ad-heavy on the free tier but the data is reliable.

Built into iOS and macOS, Apple Weather is clean, fast, and accurate. If you're in Apple's ecosystem, there's no reason to install a third-party weather app.

Not a weather app, but useful when you want to share weather screenshots. FreeCVT's PNG to JPG converter shrinks screenshot file sizes for easy sharing on social media or messaging apps.

A Swiss weather service with excellent global coverage. Good for international users who need reliable forecasts outside the US.

Primarily an API for developers, but the browser interface provides clean weather data. Useful if you want raw data without app bloat.
