Starting to Use Phone Apps to Study Nature Around Me

Being someone accustomed since I was seven to look up at the clear night sky and readily identify all the constellations and brighter stars, I noticed that there are smartphone apps that do the same thing for users.  Well, I'm challenged in a completely different area: plant identification...they all look pretty much the same to me.  But I've discovered that there are also free phone apps (usually with a premium option) in which I can take a photo of a plant and they'll come up with the identification...or at least a list of the most likely matches.  I downloaded one such app and it identified one of the weedy bushes in my yard.  Maybe I'll become a plant enthusiast the way I like to look at the stars...since they're all around me it seems like it might be fun to become an expert on identifying them.  Also, since insects are all around as well why not get one of those bug-identifying apps and expand my foray into nature study...after all, we're about to enter "beetle" season in Florida.  Oh, and I see that there's an app that identifies birds from their songs...my "birding" experience was strong as a kid in South Florida some fifty years ago, but there are some different species up here in Gainesville where I now live.  And I do regularly hear strange songs without being able to see who's producing them.  Plants, insects, birds...well, that's a starter...
