I have used the Navionics USA app for over a year. Great backup GPS/depth finder for lakes and inshore marine areas. It's usually around $10 (varies with the exchange rate since it's a foreign company) but I got an update earlier today and checked the page to see what the update included. It seems the price is now $0.99! Not sure if it's on sale or they just made a mistake.
Covers waters in all 50 states with the same map data you get when you buy one of their chips for your GPS/depth finder. You can see a list of available waters here:

Here's a link to the Play Store.

There is an iPhone version, but it's still $9.99 at the moment. Still totally worth it.
