I recently downloaded the Seek app on my phone to help me identify plants and animals. Just take a photo and the software tells you what you found.
I took it along on my latest hike and put it through its paces. I started with 2 plants that I knew to see how it would do. It got them both right.
Then I used it on some plants that I was unfamiliar with. I double checked the identification online and it seemed to get them correct also.
