While we travel and hike, we have come across some amazing and free programs that we use regularly. The first is called Seek, put out by iNaturalist. It is available for free at the Apple App Store.
Seek has many uses, but we primarily use it to identify plants. We merely hold the iPhone camera over the plant, whether leaf or flower. It quickly identifies it, giving us the common name, though on occasion it offers only the Latin name.
It does not matter whether you live in a large city or rural area, or as we have discovered if you are in a foreign country. Its database is so massive that if knows every plant and every subspecies. It is truly a wonder to behold. When stumped, it offers “dicot” or “monocot”.
