Most weather apps offer a free baseline set of data and forecasts, although which features are included can vary widely. You usually will have to pay for more-advanced features, such as lightning or longer-range forecasts, and you’ll have to pay if you want an ad-free experience. One exception is Apple’s native weather app, which is entirely free and contains no advertisements. With so many weather apps on the market, it may be worth first exploring what you can get free. To give you a sense of typical pricing, AccuWeather charges 99 cents a month for Premium (no ads) and $1.99 a month for Premium Plus (no ads and extra features). Carrot Weather has paid versions from $1.67 to $3.33 a month, the Weather Channel is $1.99 or $4.99 a month, and Weather Underground is $3.99 a month.
