Simple charts review

Very impressed with the app. We have taken it along on a handful of trips down the ICW from southern VA to Key Largo. The instruments panel including location, speed, distance, etc has matched my garmin installed onboard in every instance that they were side by side. Love the detail in the raster charts rather than the electronic charts on the garmin much more appealing to look at. My wife and I really enjoyed the course export functionality that allowed us to share our course with friends which has come in handy.

Really like the app and have already gotten more than $10 worth of enjoyment out of it. Hopefully the developers will continue to add new features. We requested several features which we would find useful and think others on the water would as well. They stated that they would be adding these features to a list of enhancements they have planned so time will tell if they get added.

simple charting app review...

Over the past few months I have tinkered with several charting apps available ranging from free to upwards of $30 and I have come to the conclusion that simple charts is by far the easiest to use and most complete app available. The app is the perfect compliment to my onboard system and functions smoothly as I go in and out of cellular or Internet service. As the name indicates is fairly easy to operate and the learning curve is low as I compare it to most of the others. The feature set is much more than I anticipated and caters very well to my needs. The documentation is on the light side but I found the FAQ section useful, the support email allowed me to contact the developers and get the remaining questions I had answered. I was pleasantly surprise at the quick turnaround on the email and the tone and level of detail provided led me to believe they actually cared. highly recommended.

great no hassle simple charting app

This thing is perfect for fishing and cruising it is stupid simple to pick up and figure out how to use. From the start it was able to accurately plot my location on the chart, I was able to clearly see the NOAA charts for my area (south Florida), I was able to easily add waypoints to the chart for where I wanted to be.

I noticed that the speed and location seemed to be right on and the apps calculation of when it thought I would arrive at my next location was relatively accurate and seemed to update itself as I changed speed or course.

I used the app over the past weekend strictly on my iPhone and decide to purchase for my iPad and was pleasantly surprised to find out that I would not be charged for the second copy which made the purchase well worth it as I essentially paid $5 per device.

Other top notch features I found particularly interesting was the ability to adjust how transparent the NOAA charts were so you could get where all you could see was the NOAA chart or add in the satellite imagery in the background just visible enough to add a great deal of detail.

The topographical maps are not the best but I can't penalize them for it as it is a marine charting app but if they added higher detail topo charts the app would be highly useful as a hiking app as well.

This app is well worth the price.
