I have one app for iphone/ipad which have different screen aspect ratios… and now the loading screen looks bad =(
Is there any solution?

I think Expo team needs to clearly define the min specs for the loading.backgroundImage and clarify how it will work with different screen aspect ratios and resolutions. The same goes with the loading.icon. If we create multiple asset files for different resolutions using an online tool for android and ios, would Expo be able to pick them up appropriately based on the device (see React-native docs http://facebook.github.io/react-native/releases/0.44/docs/images.html#static-image-resources)?
