Have [users of Apple iPhones who have purchased NAVIONICS charts] been happy with the performance of the Navionics software?

The NAVIONICS charts for the Apple iPhone were the topic of a prior discussion. See

Considering the extremely modest cost of these charts, in the range of $5 to $10, I don't see much risk or downside to investment in these charts.

I believe that the software downloads for the iPhone are sold through the Apple on-line store. I think that the Apple On-Line Store provides a rating and user reviews on most of the software. If you are interested in buying software for the Apple iPhone, you should check the Apple Store for possible ratings and reviews.

I use the iPhone Navionics program quite a bit, but not for navigating - too small for my eyes. What it is good for is showing a close up area you want to send someone, then taking a screen pic with the iPhone and emailing the photo to the person.

Also, Navionics is looking into an all new add-on for the iPad that will give Garmin Homeport type exporting capability of Waypoints and Routes for most Chartplotters.

I have an iPhone and have used Navionics Marine charts for about 1 year. This is a great bang for your buck. it is not to used as a primary navigation device, but is a suitable backup.

Excellent tide/current interface
Backup for primary GPS
Good planning tool

Should not be used as primary GPS! Navionics has disclaimer suggesting such.
Accuracy of ~100 feet in my experience

Difficult to activate features within map

Great backup tool and trip planner. Leave primary navigation to a compass or dedicated GPS.

I have them on my iPhone. Seattle to Alaska was $5 when I purchased them, so hard to go wrong. The charts are essentially the same as the ones I use in my Raymarine C80 and are quite good. It's nice as a backup, but the GPS accuracy leaves a lot to be desired. Perhaps the best part are the tide and current predictions. They are really easy to use (much more so than Mr. Tides on my Mac or the C80) and seem accurate. Definitely worth $5 or $10.

At a cost of $5, I would be inclined to buy one and give it a try. I understand that boaters like to make a thorough investigation of a marine electronic product prior to making a purchase, but at this price point, I don't see what there is to lose. What other $5 chart options are there? Even one paper chart cost four times as much. If you buy a Navionics chart for your Apple iPhone and don't like it, you can always start a JIHAD AGAINST iPhone CHARTS as an option.

I purchased it on Friday and used it a good amount this weekend. I found the charts to be extremely detailed and accurate in my neck of the woods. It is actually more accurate than my fixed mount Garmin, but in all fairness, that unit is a bit older. It is a no brainer for $5 and would be a great back-up and potentially a primary if you are not very GPS reliant. I rarely use GPS any longer because I primarily boat inland and I know the creeks pretty well. Pretty cool software. The IPhone constantly amazes me!

I have used it for the last two weeks while I try and decide what GPS to put on my new boat, 150 Montauk. It works well and is helpful. I will continue to use it for backup even after I decide on a dedicated GPS.

BC, Canada maps are what I bought and I use mine a fair amount. Not really for navigating, however. It is really detailed, and provides a quick way to check out some places to go on the fly, from anywhere.

I have seen some pretty bad positioning of the dot in google maps, not to trust my iphone navigation features.

I really like the tides features, such as the details about markers/buoys, and the marina/port info.

For the cost, pretty good. But I wouldn't trust it as a spare, or in my ditch bag if I had to bail.

I agree google maps or quick fix from telecomm towers will not always be as good as pure GPS fix, which should be better.

As your not likely to get a quick fix postion offshore I don't think it's worth comparison or valid.

What ever you carry in your ditch bag adding an Iphone or other GPS enabled smartphone can only be a plus but not as a replcement for more dedicated hndheld GPS or PLB devices which are normaly waterproof.

As already stated, How can you go wrong for $5.00. Very detailed charts. For the most part I use it for the tides and POI. Just a backup to my Lowrance
