For all of you that make maple syrup...My friend created this app called "MaybeMaple" that will identify a maple based on pictures of leaves, bark, or twigs! It uses one of the best AI algorithms for identifying plants. It really works! It also has a sense of humor when it comes to things that aren't maples. Best thing...it's free.
