i Sail GPS : USA NOAA Marine Chart Plotter App Reviews

44 add

Not recommended

This app seems to consume the processor, as zooming in / out and moving the map around takes several seconds to respond, and battery life is short when its running. It was the only app I could find to show GPS position on a NOAA chart, but it really needs work to make it more responsive.

Excellent navigation app!

I use this app every time I sail. It is accurate, has many great options and has a very detailed help section. I reported a minor issue and a new version with the fix was released within a few days.

Great apps!

I purchased both iSail and iHike apps this year and they are both TERRIFIC! They were easy to download and easy to used. I sailed both offshore and inside small harbors in New England and found the iSail app to be incredibly useful. I chartered a sailboat this year and the chartplotter mounted on the boat was old and lacked detail. I found the iSail app especially useful when going in and out of small harbors, which required knowing precisely where I was relative to the shallow areas, which I needed to stay away from. It was no problem holding my iphone while steering the boat. I still brought hard copy maps and used the boats compass, but this app greatly enhanced my ability to safely navigate, especially in tight places. iHike performed just as well when I went horseback riding on 80 miles of unmarked trails in Colorado in a area that was "off the grid" (I gave a separate review on the iHike site). Thanks for making such great apps!

Server problems

Constantly fails when downloading charts. Do not buy!

Doesnt work for me

There are no maps for the Tennessee River, I want my money back.

Unuseable!

Sorry that I bought this. Slow. Unworkable map loading even on wifi!

I quit using it

It seems to be an OK sailing app. but I couldn’t get past the way it stitched the “paper" charts together (there seemed to be trouble at the seams, and loading the charts when I needed them, etc). I have SEAiq on also and ended up always using that instead. It’s $10 so also a good value. I wish I hadn’t have spent the money on iSail because I never use it now.

Great app!!

Very reliable. Accurate. Advanced features. Great for the ipad(with gps). A bit of a battery hog in track mode so be prepared with an alt energy source.

I like it!

I use this app in combination with a vector chart app. The NOAA charts are much better than vector charts at displaying names of places and features. I use iSail for planning and general navigation, then switch to the vector app when going into tight places where their extra detail and course-up feature is helpful. It is a bit hard to be sure you have downloaded all the charts you will need for a cruise. It would be very helpful if the "Coastline Locator" feature would show all the NOAA charts available in one color, then the chart you have already downloaded in another.

Great app

I use this app when I go open water rowing. The iPhone is in a waterproof pouch in a storage compartment of the shell( boat). After the row, my track is displayed on the beautiful noaa map. I hope that a companion apple watch app will be offered so that the iPhone app can be controlled from the wrist. This is a wonderful app.

Excellent App!

I will preface by saying that I have never used a charting app before so my baseline is limited. That said, I found the app very intuitive and easy to use when navigating a sailboat through some reefs while sailing from St. Croix USVI to Fajardo, Puerto Rico. I also appreciated the very prompt pre-purchase e-mail response from the app developer to a question of mine.

From the first time we used this app, we were impressed with its ease of use and clear interface. We downloaded the charts we needed with no problems. Many guest crew members have used it successfully and found it easy to interpret. We used it to navigate from New Bern, NC to the Delaware River in NJ and currently on the Chesapeake with very few problems. A great app for the price!

Navigation program

A real navigation program worth far more than its $8.00 cost. A bit tedious loading NOAA charts, but well worth the required effort. Used on recent yacht delivery on St Johns River Florida USA with perfect results. The up to date marked charts big help. Kept me and my crew on track through somewhat complex unfamiliar waters. Prevented two near groundings. Every boater with an I phone should have this program. Perfect for small boats with no other navigation equipment. Shows "course/up" and can be used by anyone with basic boating course qualifications. I hold a US Coast Guard 100 Ton Masters License.

Good waypoints, charting not great.

The waypoint functionality is good, but Marine US has much better chart functionality. Its annoying that you have to download individual charts.

Miss

App does not work. No maps to be seen. Very nice information under help but no maps are visual and it cannot find my location, using multiple wifi connections to check.

Capt. Ray

Not a user friendly software, not ready for marine navigation.

Works way better than I thought!!

The noaa charts are great. Its intuitive, tracks very well. Since this is the 3rd gps program for sailing on my iphone, I know what I want from the App. I was able to set waypoints and plot a route pretty easily. When you turn on tracking it works really well. Like showing details of us circling to Anchor and later motoring on a dingy to shore and back. The only caveat is if you forget to turn off the tracking when you get home it will continue to track and delete your previous tracks when the memory becomes full. One of the interesting features is the ability to email a copy of the chart with your track and current location straight off the app to your friends or to post on Facebook. I havent tried it yet but its an interesting feature. The only thing that I had spent time figuring out was how to change the course heading and bearing from true to magnetic. If you click the "help" button, its got a lot of details on how to use the app. And of course you know that because it relies on the GPS on your phone you dont need to be connected to your 4G or Wi-Fi. Just remember to download the charts before you leave home. Im giving it a four star, but it should actually be 4.5. When I use the app again I will further update. All the other crew on the boat were also very impressed and said they are going to download the app.

Clumsy

Hard to use

Needs a lot of work on usability

The designer of this software made some rather inexplicable decisions that make it much less intuitive to use. Some suggestions for improvement: 1. Let the user download chart KITS not individual charts. By requiring me to download individual charts I am almost guaranteed to find myself in a tiny, complicated harbor without the local chart and no cell signal. 2. Use the current map focal point to load the local chart rather than loading based on my current location. Sometimes I like to see the map of where Im going BEFORE I get there (and I do not want to have to dig the chart up by name when Im trying to steer a boat). 3. Add "use map" to the "add waypoints" screen. Does anyone really enter waypoints by manually entering lat/long coordinates??? Kind of impossible without a paper chart for reference! As it is right now this software is kind of useless for anything but simple day sailing where you will only traverse 2 or 3 charts in one day.

iSailGPS, I LOVE it!

This is, hands down, my FAVORITE app. There are others that I use more often, but only because were only out on the boat now and then, and only in the summer (this being Alaska, winter is NOT conducive to boating). I think that it is fantastic that I can track our progress from the passenger side (or anywhere else) and make sure my husband is aware of any possible obstacles that I see on the chart, that may, or may not, be showing up on the main GPS. The only improvement I would like is the tracking line. Its kind of hit-or-miss. Some times is shows, sometimes it doesnt. No biggie, but it would be nice if it were more consistent.
