Graphical tide display on your Apple Watch, iPhone and iPad.
The watch app displays a tide graph and highs/lows for the day and allows selection of any location configured on the iPhone app. Several watch complications are provided to allow display of tide level and direction at a glance on any Apple watch face. Enable time travel to see the tide level at any point in the day.
On the iPhone an interactive tide graph is displayed by turning your device to landscape mode. Then touch the screen to see the tide at any time in the 24 hour window. No network connection is required, so you can check anytime, anywhere.
New on iPad you now see a month-to-month tide calendar. Use it to easily plan your beach activities a month or more in advance. Allows navigation through the coming months or backward if you want to see what the tide was on a past beach visit.
Runs on the current XTide 2.x codebase. This adds thousands of U.S. tide locations and currents. Current prediction is now supported for some locations within the U.S. only. Currents must be enabled in the application settings menu. We have also added the ability to configure the number of days of tides to display from one to fifteen days out.
Tide station selection has been improved. Stations can be selected either from a map or from a list view arranged by country and state or province.
*** Regarding Tide Station Locations and Currents ***
ShralpTide2 contains a wealth of tide and current information for the United States thanks to the NOAA. At present the NOAA is the only provider of data for current prediction. Prediction of currents is not available for countries other than the United States.
Additionally, though tide station information is available for some countries outside of the United States, many tide stations that were previously available in the original ShralpTide are not available in ShralpTide2.

Perfect for surfers
I use this app for surfing in Southern California. It’s the best tide app out there because when turn your phone sideways you can drag your finger to the exact time and tide along the curve. It works great and the developer will respond to your questions.
Just updated ShralpTide 2. Everything seems to work fine.
iPhone 11 running 14.7.1
Awesome app. Needs updates
Been using this app for years now. Love it! Thank you for putting it together. Unfortunately in the latest iOS 15.0.1 the ability to move the tide cursor when holding horizontally no longer works. Are there updates planned to fix this?
Best tide app
As a surfer, I think this is the best tide app out there. When I lost access to it when I upgraded my phone, it was a struggle not being able to use it. The landscape mode interactive graph is what makes it special. It makes it easy to find those target tide windows that make surf spots turn on and off, and know exactly when you want to be there.
