For .99, you can view all the charts, but you don't get a lot of the features. For 11.99/year, you can cache whatever charts you want for offline use, and they all get automatically updated, whenever NOAA updates the charts. We also set up the app with a "Test Drive" button. You have to pay the initial .99 to get the app, but you can Test Drive all the subscription data and features before deciding to subscribe. Test Drive works for one full app run, and you can do it as many times as you like. Also, you can browse the charts on our website: http://www.tryskipper.com/charts/ http://www.tryskipper.com/charts/
