Check The Ocean Tide Forecast

Tide and tidal current information for over 4000 locations in the United States and U.S. territories. A network connection is only required to display the map data in the Local Stations view.

MultiTide is designed to help you plan for anything from a trip to your local tidal pool to a multiday kayaking trip. Change the prediction start date to see future (or past) tide events. The three station tabs allow you to switch between tide events for up to three different stations which is usefully for planning trips that start and end at different locations.

SeaNav is a Universal app, which works on iPad, iPhone and iPod.

SeaNav uses Digital Vector charts providing a wealth of benefits and advantages. Buoys, Lights, Bridges, Depth Contours, Depth Soundings, Rocks, Anchorage areas, NOAA Weather Buoys etc. are all selectable and have real time distance, bearing and detail information. Turn off layers to de-clutter the display and only show what is important at the time. Tides, moon and sun times and weather are also all available at your fingertips.

SeaNav’s unique AR view mode allows you to view buoys, lights, ships, waypoints and track overlaid on your iPhone or iPad live camera view. With "AR LockOn" you can select a target on the chart and then be guided to it in the AR camera view.

SeaNav lets you measure distances and bearings and record waypoints on routes. When at sea, the app’s Sailing HUD shows your position, Course over ground (COG), Speed over ground (SOG), Vector Made Good (VMG), Estimated Time of Arrival (ETA), Distance and bearing to next Waypoint. Waypoint reached alerts, auto-routing to the next waypoint and collision alerts.

SeaNav has free Apple Watch and Pebble Smartwatch apps available.

Lowrance, Simrad and B&G GoFree support included.

Your purchase of SeaNav includes 12 months of free updates to the included US chart set. Further chart updates are then available via an in-app purchase. Charts for other regions including Canada may also be added to your product via optional in-app purchase.

Requires iPhone or iPad. GPS only required for real time route navigation. Optional Real time AIS, Tides and Weather information require an active internet connection.

Real-time route navigation requires a GPS location. iPhone devices and iPads with a cellular modem already have a built-in GPS, even if they do not have an active service plan.

If you have a WiFi-only iPad or iPod you will need an external GPS receiver to enable navigation. Inexpensive 3rd Party units are available to add these accurate location capabilities to your device via bluetooth.

Please note that continued use of GPS running in the background can dramatically decrease battery life.

This program is distributed in the hope that it will be useful. SeaNav should only be used for basic navigation reference and should not be solely relied upon to determine precise locations, proximity, distance, or direction.

Now available, the #1 US Tide Prediction app has redesigned for iPad with extra features like saved tide tables, calendar date picker, built in map, improved graphics, and more.

Tide Graph HD uses the harmonic predictions from thousands of US coastal stations and presents them in a fun and interactive graph. And now, in version 2.0 you also get an intuitive graph that shows sunrise, sunset, moonrise, moonset, and moon phase at a glance. Save recent locations, find locations using GPS location, and save graphs for later.

Tides have a great influence on the lives of boaters, fishermen, surfers, coastal communities, marine life, and vacationers just to name a few. Directly or indirectly, the great flow of our massive ocean bodies of water impact the daily lives of everyone on this planet.

The cyclical movement of the Earth's tides are caused by a combination of the gravitational forces of the sun and moon as well as the shape of the costal region. Unlike simple tide clocks that you can buy in novelty stores, more accurate tide predictions use special data gathered by instruments located at each tide station. The data from these measurements are used to determine the harmonic components which then feed into the mathematical algorithms which predict tides for the future. The end results are tested for accuracy and adjustments are made as necessary.

Tide Graph has US owned Tide Stations Only. An internet connection is required to get the latest tide graph. - See TideGraph.com for a complete list of stations.

iCTides for the iPhone and the iPod Touch provides predictions of times for high and low tides for over 4400 costal locations around the US, including Alaska, Hawaii and overseas US territories. Times are displayed with clocks that feature beautiful background images of tropical and ocean scenes. Soothing sounds of the ocean play in the background (can be disabled).

Features:

- High and low tide predictions for 4400 US costal locations.

- Tide location can be selected from a list or via points on the map.

- Also displays clocks for:
- Current Time
- Next Sunrise
- Next Sunset
- Next Moonrise
- Next Moonset
- Next Full Moon

- 55 background images that can be shown individually or as a slide show.

- Animated sweep second hand using a fishing pole and hook on the Current Time clock.

- Plays soothing ocean sounds in the background (can be disabled).

- Can be set to keep the iPhone on continuously for desk displays or to turn off automatically using the current iPhone settings.

- Tide and other times are calculated locally (no net access required for predictions).
