It rocks. Gotta move boat in 2 days and no longer have I phone (bye bye Apple) and lost free nav app. This one rocks once you get the chart downloader learning curve down. It does what you need it to do with no monkey business. I am going to buy the paid version as a thank you. This app is great.
Very good aplication. Have a different app for lap top that will only do GPS via RS-232. My lap top has No serial ports. Would this app work on Windows computer with external GPS Blue Tooth input?? Very good Android app as it is. Very helpful working on 55 ton passenger tour boat.
Charts could not load on SD card With limited core memory it is important to be able to load data / charts onto the SD memory card. I hope, in the future, this app will accommodate SD memory.
How do I load chart 81715 of Kwajalein? I found a hard copy I can buy, but no RNC that includes Kwajalein or Marshall Islands. Have to enable the Assistant Menu to get to the menu button on Samsung Galaxy S7. Inconvenient having to load new charts and figure out which chart you need next.
Great, works well for a phone app.
Junk, does nothing,
* update to latest Android version
* soft menu button to open menu
* update of GUI (holo or material design depending on android version)
* updated of download links (New Zealand)
* minor bug fixes
