On that Aziz Ansari show (Master of None) they mention an app idea called “Trazam”. A Shazam for trees. Point your phone at a tree to identify it.
There are similar apps available now: For flowers and butterflies and another that specializes in Plants in a few different regions.
I’m looking forward to finding one for trees because I’m embarrassed to keep titling these photos “red berry tree”.
Edit: Crabapple!
