Can see a simple route design widget in spline that can be a nifty ux for a climbing thing that uses the app ID.

Can you clone an Instant AppID?

I know I am just thinking out loud - but its pretty easy to envision how to use these neato tools and services that have been cropping up recently... Its inspiring.
