I'm developing a PostgreSQL–PostGIS database on a remote server. I’ve already created all the necessary layers and their attribute forms in QGIS. I now want to use it with QField. When my Android device has internet access, everything works perfectly, but I’m wondering if it’s possible to make it work offline as well ?
If that’s not possible, would it be feasible to create a duplicate QGIS project with the same layers and all the data, and then develop an app to import the data collected offline into my PostgreSQL database ?
