I have been using plantnet for a few years and have been pretty happy with it. The ability to contribute+validate your identification is great.

It does fail sometimes but it's pretty good, and the UI has improved in recent releases.

I have to agree on PlantNet. It is good enough to come up with a general name of a plant (ragwort), that you can then look up in a local plant guidebook to find out the specific variety (common ragwort).

Hopefully, a privacy-friendly phone (ie Apple) manufacturer acquires them and does deep OS integration with the app.
