You must pay for all charts – NaviPad Free Review

This is not a free app. When downloaded you must pay for any chart you want to use (which I understand) but most apps at least will provide you with a sample chart. Without the sample chart you have no clue how accurate they are. From the pictures of charts in app store they look very cheap. I would stay away from this app!
