Using GPS to find Tidal Currents at your Position:
Using your Smartphone or Tablet’s built-in GPS, this app will find the two closest tidal current stations to calculate your present tidal current based on your GPS position.
You can quickly refresh your boat’s tidal current based on the updated GPS reading by touching one button.
Finding Tidal Currents at a Tidal Station Based on a Date:
After selecting a date, you will see a single tidal current station's details. You can drag the map to display the desired region then tap a tidal station marker. A graph displays the 24-hour tidal current predictions for the selected day. A table is shown with slack, peak ebb, and peak flood times.
