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.

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.

Bristol Maps is designed specifically for commercial fishermen to navigate using the latest satellite imagery. Currently serving Bristol Bay and Copper River watersheds. Say goodbye to outdated maps and inaccurate information - our app utilizes the latest, detailed images for increased efficiency, safer fishing trips, and a higher return on investment. As a fisherman like you, I've always used NOAA charts for the Bay. Given how fast the environment changes, these are at best, unreliable and at worst, dangerous. For this I developed Bristol Maps, an app that leverages curated satellite images taken during low tide, displaying the current bar locations, and allows for multiple images to be layered. For areas with multiple images at varying tides, this app allows you to see where there will, or won’t be navigable water. Additionally, these images can be overlayed onto the traditional NOAA charts. Beyond the core mapping functionality, tide and weather forecasts are also available. Weather can be pinpointed to a location as well as the nearest NOAA zone weather forecast. This information can be combined with the mapping functionality to create digital logs. Location, catch, weather, and tide data can be integrated into a log event. Logs can be overlaid onto the navigation page and analyzed to view catch data by area, gear type (4.75" vs 5"), and weather. Feature list: * Private groups for sharing location, custom routes and waypoints. * Private group chat. * Satellite overlays available for: Naknek/Kvichak, Egegik, Ugashik, Nushagak, and Copper River. Updated seasonally. * NOAA overlays available offline for all of Alaska. * Location grid layouts, organized by color and number, which can replace traditional paper maps or code tables shared by Groups. ie: "I'm over by green 22." A search tool is included to quickly find locations. * NOAA tide charts available offline for Bristol Bay tide stations. Other locations downloaded as they are used. * Pinpoint weather forecasts available as well as NOAA zone weather forecasts. * Boundary lines (with “alarm” functionality), for all major districts are preprogrammed along with the ability to create new boundaries. * Create Waypoints and Routes. These can also be exported/imported to/from other users to share data. * Online maps can be streamed with NOAA charts, custom satellite views, a high-res AK Government view, and street view. * Log entries for recording opener times, district, pictures, sets/deliveries, and automatic tide/weather history. Bristol Maps has been designed with an intuitive, user friendly interface to solve a common fisherman problem. Bristol Maps Pricing $200/Year A one-week free trial is included for testing and includes free cancellation. Subscription includes updates, bug fixes and seasonal imagery additions.
