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.
This plugin will most probably not be developed any further. For another (working) take on importing (and exporting!) data from iDAI.field to QGIS see the soon to be released Field Connect Plugin: https://github.com/gbv/field-connect
The python packages requests and json need to be available.
