@Suty The fact Windy hasn't implemented its own dark theme for these UI elements is why I still hesitate to subscribe to premium. Reading the forecast panel with its bright white background on web or in the mobile app hurts my eyes, and applying any third-party color filter extensions (e.g., Dark Reader) makes layered elements look awful like the above.
The only solution is not to rely on the operating system or an extension, but to design a native dark theme for all of your own UI elements as a companion to your default theme, then let the user choose inside your app. I will go premium when you do that. Until then I must keep looking for something that is not a step backward.
