Ratings and reviews

First-time user hostile app. I tried to give this a shot while looking for similar apps with great experiences and information quality, but I couldn't even try it before giving away my info to create an account. Then, it seems like they won't allow the app to run very long on my phone that uses a more up-to-date and more secure version of Android called GrapheneOS. Please fox these items so I can use your app safely and use it at all before creating an account. Thank you!

Game Changer! Fast, Initiative and Incredibly Useful. The charts are accurate and were easy to load and navigate with. The integration with a Sounder is beyond cool, as I can now have a handheld remote when I'm on the back deck on the kicker and I can't see the main display. fully compatible with my FCV800 via Wi-Fi connection. Not a single hiccup. I highly recommend this ap.

Best navigation app on the market. Charts are unmatched, updates are timely, and there is a professional polish throughout whilst remaining terribly easy to use. Whether you are running around in a tinny, cruising the coast, fishing or operating commercially, this app can satisfy all demands.

What’s new

Version 4.1.0 :
- New 3D Chart View Control : If you prefer to navigate exclusively with traditional 2D charts, you can now disable Perspective View (3D). Once disabled, your chart stays in 2D when using the GPS button or following an active route. Access this option from the settings.
