What is the current best weather app with free API?

OpenWeatherMap-Alerts-Weather-Driver

This is pretty much what I did. As for the API, a free one is provided without the need for a payment card. With the free one, I get current weather, 3-hr forecast 5 days and basic weather maps, weather dashboard, air pollution, geocoding, weather widget and 95% uptime.

You mean this one? I thought this was free... at least I haven't been paying for it
