Field Drops app for iPhone and iPad

Field Drops is an augmented reality app that plays nature sounds. Point the app at a tabletop or desk, and when the green square on your desk appears solid, tap it to place the AR content. Then tap any of the AR squares to play the sounds.
This was built as an augmented reality interaction experiment using ARKit and RealityKit. 
The sounds were all recorded by me :) Two of them were from Belize, one from Pennsylvania USA, and one from Virginia, USA.
The tricky part of this was to use animation subscriptions to cause the AR content to continually rotate during the time that its sound is playing back. I made this code available for use on GitHub.
The logo was made by my daughter.
