Is it possible to check which variant of the filter has the best statistics in the effects that include UI picker or “Tap to change” option?
The stats in Spark and Lens Studio are limited to what they give you.
It used to be possible in Spark with the networking module. You would hit your server with a request and it could send it to an analytics platform like Google Analytics. Unfortunately they removed this capability “for now”
Lens studio docs specifically say this isn’t possible on their platform.
Currently we do not support integration with external services or APIs within Lens Studio beyond our servers
It would be possible to log analytics in native apps that use ARCore or ARKit. It is also doable with webXR.
