Field guide for your fone

This is quite a good recommendation for the iNaturalist smart phone app, and it also earns the TPP seal of approval.  It does a great deal for you. TPP supervises a master naturalist project to document the flora of a conservation area.  Each observation is not only recorded digitally it is GPS located and pinned on a map.  Some things don't work as well as others in terms of suggested identifications, but it will put you in the ball park.  For example, SYCs, which stands for stinking yellow composites (sunflowers).  You need more than a picture of a flower/inflorescence to sort them out. The app also works well on animals too. And it's free.  If you like nature and like knowing the names of things (a human trait), then you must get iNaturalist.
