I use them. It helps me identify "weeds" so I can know if they're good for pollinators or have to be removed immediately for invasiveness.

Example: I often keep a couple milkweed plants growing for monarch butterflies.

I forage and hunt for food. It lets me get things I can't get at the grocery store and it's free.

It's for beginners. My son uses it to learn about plants in our yard.

It might be wrong, but that's the next step of parenting.

Been using one of these apps to try to identify the many wild plants in my native pastures. Mostly just out of curiosity and conservation. Likewise it helped identify some trees and shrubs the previous owner planted around the yard.

They are far from perfect but are a good starting point as you get lots of pictures to compare to your mystery tree, you finish the job yourself.
