What is Marine Navigation?

Marine Navigation is a GPS chartplotter app designed for sailors, fishermen, and sea lovers who want freedom and control — even offline.
No expensive hardware, no recurring fees: buy it once and it’s yours forever.
Since 2009, it has been a reliable companion at sea, trusted by thousands of navigators worldwide.

Why should I choose Marine Navigation?

Because it’s simple, affordable, and powerful.
• Works fully offline, even in open waters.
• Easy to use: activate the app and start navigating immediately.
• Cheaper than subscription-based systems — save hundreds every year.
• Guaranteed privacy: your data stays on your device.

Which devices are compatible?

Marine Navigation works on both iOS and Android smartphones and tablets.

Is Marine Navigation available in different languages?

Yes. The app is available in: English, Italian, French, German, Spanish, Indonesian, and Turkish.

The Full Version gives you access to:
• NOAA Raster & ENC (U.S. official charts)

How often are maps updated?

It depends on the providers (NOAA, ESRI, OpenSeaMap, etc.). Updates are published as they are released by each source.
With PRO, you can also create your own custom maps or import S57 electronic charts purchased from authorized sources or released by oceanographic institutes.

Does Marine Navigation work worldwide?

Yes. The app works anywhere with your device’s GPS. Map detail depends on the selected layer, but you can always add your own custom maps with PRO or use S57 charts if allowed or purchased from official providers.

Does Marine Navigation work offline?

Yes. All downloaded maps and GPS functions (routes, waypoints, anchor alarm) work completely offline. Internet is only required for downloading new maps or updates.

Does Marine Navigation use my phone’s GPS?

Yes. Marine Navigation works only with the GPS integrated in your device. External instruments such as AIS or NMEA systems are not supported at this time.

Does Marine Navigation drain the battery?

Continuous GPS and screen use reduces battery life. We recommend using a boat charger or powerbank.
Tip: reduce GPS update frequency in settings to lower battery consumption during long trips.

Can I use Marine Navigation on multiple devices?

Yes. If you use the same Apple or Google account, you can install the app on multiple smartphones or tablets without paying again.

What happens if I reinstall the app? Will I lose my data?

If you reinstall without deleting the app completely, your data remains.
If you delete and reinstall from scratch, your data will be lost.
Always export waypoints and routes (GPX) or use Web Sync before deleting the app.

Can I share my routes and waypoints?

Yes. You can export and share them in GPX format via email or other apps. Offline maps, however, remain tied to your device.

Can I try Marine Navigation before buying?

Yes. You can start with the Lite version to test basic features. Then you can choose between a one-time purchase (Full Version) or a subscription. Later, you can upgrade to PRO for advanced tools.

What is PRO and why should I upgrade?

PRO is an optional subscription that unlocks advanced features:
• Unlimited custom maps (any image, any size)
• High-resolution map import, overlays, and transparency control
• Worldwide offline tides (powered by FES2022b)
• Advanced anchor monitoring with visual circle, drift alerts, and Watch Mode

How do subscriptions work?

The PRO upgrade is offered as an optional subscription. The Full Version you purchased remains yours forever.
• Optional: PRO is not required to use the app, only to unlock advanced tools.
• Automatic Renewal: By default, subscriptions renew at the end of the period.
• Manage or Cancel Anytime: Disable auto-renew in your Apple or Google account settings at least 24 hours before renewal.
• Keep Your Data: Canceling disables PRO tools, but you keep all your maps, routes, and waypoints.

Is Marine Navigation legal for professional/commercial use?

Marine Navigation is a powerful support tool but cannot replace official certified charts. Professional and commercial use always requires official charts onboard. Use is at your own risk and with full attention during navigation.
