Pretty good for North up

Been using the app for about 3 years, mostly the paid ipad version. Works well and the maps for perth local waters are fairly good. The customisation of the maps is also good, though not particularly intuitive to set up.

Main issue I have is when I select head up or course up for map orientation. Sort of works providing you don’t pinch and zoom too much. Frequently flicks back to north up, occasionally locking me out of selecting head up again without force closing and restarting app. Bit annoying when you’re heading into a reefy bay.

Developer Response ,

Dear Customer, as you’ve correctly noticed, each time you tap on the screen or zoom in or out, the chart rotation will automatically set to "North Up". Change back to "Heads Up" or Course App by manually tapping on the GPS icon (lower left corner of the map screen).
As we continuously strive to improve our products, we have also forwarded your suggestion to our developers for possible future App updates and we thank you for your contribution. Information regarding updates to existing Navionics products and new product releases can also be found on our website or by following us on Facebook/Twitter/Instagram. Thank you and have a nice day!

Enhanced navigation aids / tracks

I love the app and use it all the time.

If 3 distance/bearing indicators were available (only 1 currently) and a distance from target (acquired independently from radar) circles were available then GPS location could be verified from compass or radar observations.

I also retain tracks as a sailing log. Could comments be added to these for wind / sea state / observations etc. also a crew entry would allow a log to be generated for each person to allow skipper to know each crew member experience on board accurately.

Developer Response ,

Dear Customer, thank you for your message and for the 5 stars.

We value customers’ input and your suggestions on enhanced navigation aids and tracks have already been forwarded to our Product Management Team for consideration of future App enhancements.
Currently, we cannot guarantee a precise date when an update will be available. Information regarding updates to existing Navionics products and new product releases can be found on our website or by following us on Facebook or Twitter. Have a great day!

Last and long format

This is a great tool but by no means a primary navigation source, please can you add the option of choosing the latitude and longitude formats 1. Degrees decimal degrees. 2 degrees, minutes decimal minutes. 3 Degrees, minutes, seconds for when the search for the position of a coordinate is used, currently the roller dial is set to degrees decimal degrees.

It would help greatly when trying to find a position in a hurry and one is used to a certain format as well as running the same format on the vessel GPS plotters. Also saves time as recalculation would not be necessary ( search and rescue operations )

Many thanks

Developer Response ,

Dear Customer, thank you for your 4 Stars. The Navionics mobile App will only display coordinates in degrees and decimal minutes (dd° mm.mmm'). If you would like to convert the coordinates to another format, a GPS coordinate converter can be found at:
There is not a way to convert coordinates, or to display another coordinate format, within the App itself at this time, but we do value customer input and we will forward your comment to our Product Management Team for review and consideration for future enhancements for our App. Information regarding updates to existing Navionics products and new product releases can be found on our website or by following us on Facebook or Twitter. Have a great day!
