This is a simple qgis-plugin that imports geodata from a Field Desktop project into a vector layer in memory. It is an ad hoc solution produced for myself to accomplish a specific task and has no error handling right now. It works, and you could try it, but it is very fragile.
The python package couchdb
needs to be installed first. To do this, you could open the python console in QGIS and type:
import pip
pip.main(['install','couchdb'])
