#Seasons app is now accepted by Apple and will be available when Apple Vision Pro launches 🎉 apps.apple.com/us/app/season… It's not just a powerful weather app, but also a brand new immersive weather app specially developed for Apple Vision Pro. It’s a pure SwiftUI + Reality Composer Pro app, a genuine Spatial Computing app that deliberately incorporates 34 immersive weather conditions, along with Spatial Audio. Let's witness the magic unfold right before your eyes! It will be FREE for all early adopters until we figure out how to monetize it. #Seasons #AppleVisionPro #visionOS
