As of September 30th, 2015, EarthNC has discontinued sale of its retail Marine Charts apps. We will keep the chart and information servers running for the next 6-12 months (including chart updates) to give everyone time to find alternative apps. Premium Weather subscriptions for the iOS App will automatically expire at the end of the current period and will not renew.

- You’re not getting a GPS signal in the app*? Try one of the following two things to fix it:
- (1) Shut down the app completely. From your iPhone home screen, double press the Home button. Then, press and hold the Marine Charts icon in the task bar. Once it starts wiggling, press it to stop it, as you would normally do to delete an app.
- (2) If shutting down the app doesn’t work, rebooting your phone will do the trick.
- *Note: If your phone is in airplane mode, the GPS won’t operate, and the app can’t record tracks.
- If Marine Charts stops working, you can delete it from your phone and redownload it from the App Store for free (a dialog will tell you the download is free when it starts). If this ever happens to you, we’re very sorry for the problem. Please email us and tell us what happened.
