Check the tide before you head to the beach to surf, tide pool or just go for a walk or run. No network connection is required, so you can check anytime, anywhere.
ShralpTide displays the current tide along with the high and low tides for the current day and the next 4 days.
Includes an INTERACTIVE FULLSCREEN TIDE GRAPH in landscape mode. Turn the device on its side then touch the screen to see the tide at any time in the 24 hour window.
ShralpTide 1.2.4 is no longer supported. There are known issues with daylight savings time transitions and inaccurate tide station data. I have made it available for download for those who want more international tide stations and are not concerned with accuracy.
Good news! The crashing issues reported in iOS 7.1 are no longer a problem on iOS 8. So hurry up and upgrade, iOS 8 is a great release.
*** Regarding Tide Station Locations ***
Shralp Tide does not include all of the tide stations in the world. It has good coverage of the US and Canadian coasts as well as Australia, New Zealand and Japan. Beyond that there is spotty coverage of international locations.
As of version 1.1.1, currents will no longer be available in Shralp Tide because they were a source of confusion to those expecting only tides.

Good for what it does
I noticed that someone else in Southeast Alaska says Shralp doesn't have any stations in Southeast. There are two just for Juneau. And the reviewer who mentions that there are no graphs. . . You have to turn your phone/iPad on its side. My only complaint is that I can only see five days of future tides. I use the app nearly every day, but I also like to plan a week or two ahead to know when it's safest to cross Gastineau Channel or leave the harbor on an outgoing tide. Still, it's accurate and quick.
Fantastic app, no internet required
I've been happily using this app for years. It does a great job. My only complaint is that you can only look at five days worth of tides. No searching ahead. They've added more days to their newer app, so I'm testing it out. The newer one doesn't offer as many tidal stations for the area I'm visiting however.
Great App! Buy the upgrade SchralpTide2.
I have been using the free version for years. It's easy to read interface is its strength. Portrait mode is powerful for visualizing the in between tidal states. At some surf spots a foot of tide can change the game!
Pay it forward and buy the $.99 upgrade!
