Never be without the tides again! You too can carry the tides in your pocket (or now, on your wrist!) as you walk along the shore, fly into a harbor, or sail off into the sunset. AyeTides displays tides and/or currents for over 13,400 locations worldwide and unlike many other tide apps, it does not require a network connection. With AyeTides you will never see those annoying ads or be asked to pay for additional features! Sailors, harbor pilots, beachcombers, nature photographers, and more use AyeTides to plan their outings on or around the world's oceans. And there are NO ads and NO subscriptions! Here are some of the things people are saying about AyeTides... "AyeTides is a quality professional product” "Your support has been the best I have experienced!" “As a harbor pilot in New York I’ve been using your excellent tide and current app” "I really appreciate the effort that you put into making AyeTides as accurate as it can be. It is a great program that has been very useful to us. I think we have 60 pilots using iPhones and iNavX and your app links in so well." "I am a ships Pilot in BC and use Aye Tides a lot and it has become invaluable.” You can see the day’s events in tabular form, or you can rotate the phone for an interactive graph that shows you the tide’s value at any point during the day. You can find a station on a map, by name, or based on your current location. AyeTides is updated regularly and stations are added whenever we find new data. We encourage our customers to contact us if you hare having any issues with the program so that we can help you. This app is designed to run on your iPhone or iPod Touch. While it will run on your iPad, it does not offer the additional features available with AyeTides XL, which was designed specifically for the iPad. If you have multiple devices, you may want to consider our bundle. You get both apps at a discount! This is the only place to install AyeTides. Other websites may look like they have AyeTides, but they do not. We only support iOS, any other version of AyeTides is not ours.
