I use windy on a daily basis, mainly for my job in skydiving. It would be convenient if the mobile version would have a slider to scroll through the altitude for data. Currently you can place the weather picker and open de side menu to adjust the altitude, but then the window obscures the view, so you have to change the altitude, close the menu and then see the windspeed for example. Having a slider where you can instantly see the date (like the web version) would be an extremely convenient feature.
Cheers
