Been recommending it for years!
I guide plant and flower walks and help people of all experience levels learn to identify plants. This isn’t the only tool I use but it is way more accurate than the Seek by iNaturalist app (which I also love but rarely trust more than a family or genus level ID). I adore that this app essentially lets me query a database with all the information I have about the plant. It also lets me search for the plant or group of plants I am looking for, and it includes shrubs and trees. My only gripe is that the pictures are often not great, I could use more close-up leaf pictures for instance - but for a free app that doesn’t purchase copyrighted photos, I can’t expect more of it!
