The app is ok! I would like the ability to return to the map coordinate screen without having to close the app!

1.51 update got things rolling again

Now app is able to pick up the market data and calculate coordinates again!

To reviewer who mentioned the 'scuba trips', that's par for course in geohashing; not every grid will have accessible coordinates every day. Hit the 'East' button on those days if you're on the Left Coast ;)

I love the idea, but

I seem to be having a problem getting the app to give the coordinates. It will give me the correct coordinates, but only for dates starting three days ago. I think the idea is awesome, but not if I get data several days old.
