Loops is super simple atm, and it's important we get the basics right.
That being said, our R&D "department" has successfully implemented custom AR filters in the Camera (similar to Snapchat filters), and will support user contributed AR filters.
We are a few months away from this being available to users, it will likely launch on iOS first with a limited deployment while we address performance/bugs.
The goal is to be the best fedi video camera app, with powerful editing tools!
