I had this app on my Sony Xperia before I got an iPhone. Setting up on iPhone was a lot easier since I didnt have to plot routes again. I was able to transfer all my routes from Xperia to this one.
They are very responsive to feedback. I had asked them to add lake Sammamish over a month back. And today I was able to get a bathy chart for this lake and I can see they have added almost every popular lake around my area.
I am very pleased with this level of app support.
