Hey lovely bubble people! 
As I’m not 100% sure if my email was delivered to @sam.morgan , I’m gonna post my contest entry here.
The app you find here is called Projectisle 
Right now it’s available for desktop view only, if you are on your phone right now, and anyway want to see it, there is a video attached showing the basic functionality.
Have a nice weekend y’all! 
*edit
adaptive mobile version available but might have some flaws
