Answers to common questions, and a direct line to the developer.

Frequently asked questions

  1. 01

    Does it work offline?

    Yes. All lights, models, flags, sounds and tests are inside the app. Only links to external sources need a connection.

  2. 02

    Why do the lights look larger than in reality?

    The glow is enlarged so you can read it on a phone. It does not show optical range, intensity or weather.

  3. 03

    Which rules does it follow?

    COLREG for lights and shapes, the International Code of Signals for flags, and IALA Region A for buoys.

  4. 04

    How do I reset my progress?

    Tap the gear icon to open Settings and choose to reset progress. Deleting the app also removes its data.

  5. 05

    How do revision reminders work?

    Choose the weekdays and time in the app. Notifications are scheduled on your device; no server is involved.

  6. 06

    Is this an official exam or navigation tool?

    No. It is for study and revision. On the water, current regulations, official publications and your vessel's procedures apply.
