User reviews

Absolute Scam

The first app which is free immediately directs you to pay for the actual app £6. The app itself very poorly designed and with very little useful information

Response from developer

Seabook has been free since 2013. There are no ads and no subscription. Simply close the pop-up and continue using the app at no cost. Seabook Master is also available, offering additional content and features, with no pop-ups and expanded materials. The app is designed to support maritime education and training, has served the industry for years, and will continue to do so with ongoing upgrades. Please consider Seabook+ for the enriched content. Many thanks for the feedback!

Outdated: navigation doesn’t work

Ironically, I cannot navigate in this app on my iPhone 16. The navigation buttons at the top overlap with iPhone menu bar and don’t respond. The font is also annoyingly large. Please update and also meet Apple’s privacy requirements as indicated in the App Store.

Need update

1.Please update Colreg with rules for sound signals as they are not visible in full version- rules 34,35,36,37
2.You can also include IALA buoyage
3.Please update for the new versions of the phones as my iPhone 15 is impossible to tab on the back button and Content button as they are in my watch and Wifi bar ( top part). To do that I need to turn my phone landscape.
4. Please make Quiz mode for Colreg exams for practice.

Thanks
