Perfect, simple perfect

I absolutely love this app. Perfect

Great weather app!

I’ve tried many weather apps but this one stands out to me more than the others. It offers a lot of features, while still staying very accurate, unlike many other weather apps that rely on less reliable information. This app's data comes directly from the national weather service, making it very reliable for people who need the data straight from a trusted source.
Although it can be hard to traverse through the apps interface and data. After a few uses of using the app, you will quickly catch on and understand how to navigate through this app. The amount of customization in the settings is far ahead of the competitors, allowing you to set your settings for your specific needs.
This app also includes the SPC predictions, a handful of models and mosaics which is good for weather enthusiasts like me. The radar is what stands out from other weather apps, it’s highly customizable and features a dual pane mode to view two different weather modes simultaneously. If you want something a step up there is even a quad pane option to view four different weather modes simultaneously. Another feature is the ability to long press a location for an instant local forecast instead of having to save a location on the main screen every time.
A small handy feature is being able to see the area forecast discussion and the severe weather ongoing in the vicinity of an area you chose.
Another nice thing about the app is that most weather apps require your GPS constantly but this one doesn’t require your GPS to function. To get all of those features for free and without any ads is rare! The entire weather app overall feels very clean, organized and professional.
excellent work!

Liking it so far!

This app has a ton of info. I will start with saying we need the proper dark mode icon when using the dark mode icons options for iOS.

Hopefully the bottom bar gets some icons for each category. Other then those things not much to say other then any ui improvements are welcomed
