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.

Ratings and Reviews
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?
I'm traveling in Nova Scotia. The original Sharlp had at least seven or eight TIMES as many tidal stations to choose from. This one has 5 tidal stations in Nova Scotia, while the original has 38! Same for the other provinces.
There are some improvements that I really like, such as being able to view tides more than five days out. The sun and moon symbols are also handy for planning night time kayak outings and low tide paddles in the morning and evening.
If they add all of the Canadian tidal stations that they removed back onto the app, I'll up my rating to five stars. Luckily I still have my original Shralp app, which I have been using very happily for years, so I still have those tidal stations in the palm of my hand.
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.
