Just tried comparing pictures of two trees (inc leaf closeups) between PictureThis and native Photos app. PictureThis got it right, was consistent re species when comparing closeups to wide tree shot, and gave lots of extra info. Photos app got the genus right but different species for the closeup and wide shots; not very helpful. The lack of organised extra info is also a pity. One of the nicest features of PictureThis is how it shows your photo vs other matching photos from its database, letting you visually confirm if the result is accurate.

Thats why I said "for casual uses". Most people probably don't lookup plants often enough, with that level of specificity required, to justify $100 a year for an app that does just that - the built in one also works for animals and food.

When I've used the built in lookup it also shows me other examples of the species it identifies the plant as.
