Buoys, Lights, Bridges, Depth Contours, Depth Soundings, Rocks, Anchorage areas etc. are all selectable and have real time distance, bearing and detail information. Tides, moon and sun times and weather are also all available at your fingertips. Our 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. In-app tools let you measure distances and bearings and record waypoints on routes to sail. When you are out at sea, the app’s Sailing HUD shows your position on the route, 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 flashing collision alerts (with Boat Beacon). External NMEA support for AIS, Autopilot, Wind and Depth Requirements: iPhone or iPad. 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 you will need an external GPS receiver or feed to enable navigation. Your purchase of SeaNav includes 12 months free updates to the included UK chart set. At the end of the 12 month period continued access to ongoing chart updates is available via an in-app purchase. Charts for other regions may also be added to your product via optional in-app purchase.

Payment will be charged to your iTunes Account at confirmation of purchase, and will be charged for renewal within 24-hours prior to the end of the current period. Subscriptions may be managed by the iTunes account holder and auto-renewal may be turned off by going to Account Settings after purchase.

There is no indication of reefs and only a rough guide to the sea floor. I wanted to use this to guide me to possible fishing locations, but the lack of detail makes it very difficult. **Developer response:** Hi, We are sorry to hear that our charts do not meet your fishing needs. Our charts contain all the detailed navigation information that the UKHO Admiralty provides. This does include the type of seabed , sandy , mud, rocky etc. for anchoring. There are depth contours and spot depths which might help identify reefs but unless they are a hazard to navigation they will not be explicitly marked. Thanks for trying SeaNav and if you have any further questions please email us at help@pocketmariner.com Best regards Steve ### 5/5 — Excellent apps. Great value *2024-05-13* Used all 3 last weekend, highly recommend. **Developer response:** Thank you very much for your kind feedback. Good feedback keeps us going. ### 1/5 — Rip off *2021-07-19* Paid subscription for charts, will not down load any ### 3/5 — Top *2021-05-02* Auf Deutschen wäre noch besser ### 2/5 — Not happy *2020-12-18* When you pay £20 pounds for something that telling you that the 10 foot of water that I am looking at is in the Submarine training exercise area I doubt it reliability I am deeply disappointed and wished I had paid a bit more for a more reliable one **Developer response:** We have checked and the area is for robot submarine testing and is an officially designated area according to the Admiralty. SeaNav’s data is directly derived from the official data. ### 5/5 — Great app *2020-06-11* I had a problem with my wifi hotspot and gps app. This was sorted quickly with email support . My settings were set incorrectly. I use the poi’s to mark my fishing spots or use as way points with the sail to option. For longer passages I create routes. I also use Boat Beacon which is linked to this app, shows AIS ships and positions in a camera view around your position Many positive points Thanks SeaNav ### 5/5 — Sea Nav *2019-10-10* Cannot get AIS information on Sea Nav despite having both Sea Nav and Boat Beacon Apps. Most inconvenient having to switch between the two for AIS Info, and using Boat Beacon gives no chart detail. **Developer response:** Hi, please contact us at help@pocketmariner.com so we can help get the AIS working for you. ### 1/5 — NOT HAPPY *2018-12-10* If your not a real Seaman and think this app is appropriate good for you!! Thanks to the good reveiws im now £30 out of pocket and would even hazard a guess at the staff and close equatances have all written a gleaming review each!!! Firstly as said previously. Depths and contours lack detail even though I made it slightly better after removing layers. It’s slow and doesn’t even load the last place you were looking at only seconds before. If your a fisherman or something equivalent and wish to have marked strings of pots or even add your own way pointed course you can’t!! The one in the pictures has been saved on the app to look at but you can’t use it. The majority of the apps time is spent trying to sell you charts or extensions of their own product. Only the yachts and dinghy idiots that don’t respect the sea and it’s dangers would use such a clueless app. And I wouldn’t be suprised if they even get mentioned in maritime enquiries following the onslaught of bad seaman ship to follow this apps use. REFUND IF POSSIBLE **Developer response:** Sorry to hear you are not happy but disappointed that you should then cast false and unsubstantiated assertions at us over our integrity and reviews. Maybe you could have contacted us first via the help links in SeaNav - help@pocketmariner.com. SeaNav has much higher resolution than other popular apps which used to slow it down a bit on older devices but now has much faster drawing on the newer iOS devices. SeaNav does do all the other things you say it can’t like Points of Interest for fishing spots etc. ### 5/5 — Used on every sail - Keeps getting better *2018-08-09* This app is great. Buy it! Actually I recommend buying the marine bundle which includes Seanav, Boat Beacon & CompassEye. This app was great 3 years ago when I first started using it and is even better now. I use it when I crew on a racing yacht - just open and click on the go sailing icon. The track and every tack taken are all recorded for later review. I also use it to plan routes for cruising and for navigation while cruising. It is very robust and stable with my iphone7 and Apple Watch (It is amazing how much useful information is clearly displayed on such a small screen). I find the 2nd (waypoint) screen on the watch the most useful. For e.g just recently I was on a long 30nm tack. I set the auto tiller to the next waypoint bearing (BWP) shown on the watch. With the occasional tilt of the wrist I could check VMG and XTE, and tweak the bearing on the autotiller to get the XTE back to 0nm. My track followed my planned route almost exactly. Very efficient! Pocket mariner are very innovative and responsive to feedback. Their apps integrate really well with each other and are iOS family shareable. I (we) now have all their apps! ### 5/5 — Ron jones *2017-04-29* Superb app, had some trouble installing but customers service by email was quick and helpful. ## Frequently asked questions about SeaNav UK & Ireland ### What is the price of SeaNav UK & Ireland?
