TideView is a unique AR App for the iPhone that allows a visual 3D appreciation of the tidal expanse.  It allows you to interact with the flow of tidal water and to predict with limited certainty where sea water will appear now, in 12 hours and in 80 years!

Tidal prediction programs are limited in their ability to predict water levels.  Do not rely on this program for anything serious in your life.
