ShralpTide

ShralpTide displays the current tide and tide direction along with the high and low tides for the current day as well as the next 4 days. Just swipe a finger to move between days.
Turn the device it on its side to view a fullscreen tide graph and touch the screen to see the tide at any time in the 24 hour window.
No data connection is required. Tide calculations are performed on the device and the harmonics data is bundled with the app.
ShralpTide is a quick and easy way for the casual beach goer to check the tides on the go.
