@idefix37 thanks for you answer. I'd love to have geopotential height isohypses on Android app, or geopotential height layer at 500 hPa. I hope developers will consider to include this in future versions!

Thanks for your detailed answer, helps a lot. It is good to see that the information is implemented in the UI but is just not visible for me. I am using iOS 12.1.2 with Windy.com v. 17.05 with an iPhone 5s. My App Store and settings tell me both the App and the OS are updated to their latest versions.
