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Outdated: navigation doesn’t work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.

Thanks, filfisher92. Enjoy Seabook! More updates on navigation, stability, safety, and ship management are on the way!

Wealth of information

There is lots of info in this app (the paid version). It’s never easy trying to squeeze chapters of information in a bullet point type app but this is a good help for those not able to do the background reading. Useful as an aid de memoir but no substitute to leaning the long way!
