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. -----------------------------------------------------------------------

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 ### 4/5 — Awesome app. Needs updates *2021-10-15* 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? ### 2/5 — Crashes *2021-01-22* Crashes and loses saved locations almost daily . Otherwise it would be a 5 star ### 3/5 — Best tide app but won’t remember my favorite *2021-01-16* Deletes my favorite locations every time I close app. Is there a fix? ### 1/5 — Reverts to La Jolla/ scrips pier every time *2020-10-16, version 3.1.20* Used to work great. Now every time I reopen my saved spots are erased and The app reverts to the default La Jolla tides. ### 2/5 — Not as good as the original *2020-10-04, version 3.1.20* I downloaded this app as I used the first version almost daily (living in the Gulf Islands BC). Disappointed that tides from Montague no longer available and no tides from Fulford or Ganges as well. If you liked the prior app for the excellent coverage in this area, you will not like this version as well. Too bad. ### 3/5 — Awesome app but... *2020-01-03* Great app for tide on your Apple Watch but you only get it in Feet and not meters... on the phone app you can change it to metric but this isn’t mirrored by the watch app... please can you update this? ### 4/5 — Generally good, but has to be reloaded *2019-08-27* Love the app. After awhile, it will repeatedly crash on my iPhone. Easily fixed by a reinstall. ### 1/5 — Trash *2019-06-18, version 3.1.6* The app is pure trash. ### 4/5 — Does work in Canada! *2019-06-14, version 3.1.6* I've enjoyed the simplicity and design of this app for years. Contrary to other reports, it does work in Canada, though not all locations are represented (someone else mentioned Gibsons). I like the precision of the (landscape orientation) wave visual, so I can find out what time the tide will be at a certain point ideal for swimming. It only shows tides for five days, but that's usually adequate for me. Recently I had a problem with it not working on my phone, but the app developer was very responsive and ultimately helped me solve the issue. ## Frequently asked questions about Shralp Tide 2 ### What does Shralp Tide 2 do?
