is there cell phone app for 'drawing' a map of plant locations while walking around?

Is there a program, an app or some 'thing' for a cell phone where you could turn it on and walk to a plant, type in a label then walk to another plant and label and even photograph it...in no particular order but the program can read where you are on the ground so that what you end up with is a map with all of the plant life marked in correct positions?

I have drawn maps, even with graph paper and that's what I'll probably do but this crossed my mind as as a way to locate more accurately.

Downside would be I'd have to turn on 'location' which I never do.
