I haven't tested it against international apps. This app uses EfficientNetV2 https://arxiv.org/abs/2104.00298

Jan 2023: New app allows easy identification of all NZ plants, animals and fungi
Imagine being able to readily identify every plant and bird in your garden, on a hike or when showing off our beautiful country to visiting family and friends.
This is from a few months ago but really interesting work from some university students that trained a popular machine learning model on data from iNaturalist.nz. The app is pretty good at identifying endemic species. The entire model is installed with the app which means that it works offline.
One of the 16 was more than three times the legal limit when breath-tested and two others were more than twice the limit.
