[Loadstone] New Idea

[Charlie Richardson]

Just a thought while walking down a street with a building marked as a check 
point.  I keep hitting select to see how many yards away i am.  While 
traveling with a cane the last thing I need to be doing is messing around 
with my phone in the other hand pushing buttons.  I almost dropped it.

Would it be practical or reasonable to add a homing feature.  I'm thinking 
it would work like this.  The closer I get to a point the faster the beeping 
would be and if I got exactly on a point it would be a straight tone.

Not really looking to get exactly back to the original point, but find a way 
to check how close I am to a point without using my hands.
