### 1/5 — Absolute Scam

*2026-01-02*

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

**Developer response:** 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!

### 3/5 — Outdated: navigation doesn’t work

*2025-02-01*

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.

### 4/5 — Need update

*2024-08-09, version 1.1*

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

### 5/5 — Diller

*2024-05-02, version 1.1*

Merhaba, Türkçe dil seçeneği var mı?

### 5/5 — Useful

*2022-10-31*

Very useful app for us navigation officer, I would like to know if new updates will be released

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

### 1/5 — Doesnt worth the money

*2021-12-17, version 1.1*

So i bought this app and its full of bugs at least on iphone 12 pro , you cannot press the back button once you have accessed any of the categories, scrolling is alao inpossible and lately i get this popup message and the payed app saying to buy the pro version which i own already and that there is a new update which is not . My opinion just stick to the free version if you really want or just try other alternatives . Unfortunately i  cannot put stars on minus cause if would and i am kinda forced to place this one star which is already too much.

### 1/5 — Very bad

*2021-06-03, version 1.1*

A very bad built for iphone 12 pro, since you cant go back via buttons you are kinda stuck in one screen if you scroll down completly. I wtotw an email to app suport a few months now still same problem.
But the information it contains it s very helpfull.

### 5/5 — Wealth of information

*2021-04-01*

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!

**Developer response:** Thank you, Waughster! Glad you enjoyed Seabook as a key information source.

### 5/5 — Vert helpful App

*2021-03-16, version 1.1*

Really helpful for seamen and students who study in nautical school.But mainly contains information for navigators but not so much foe engineers.

### 2/5 — Could be better

*2020-12-02*

Alot of errors in this. Please fix

**Developer response:** Thanks Wrighty246, noted yours to review again but haven’t seen nor received other complaints. Could you drop me a line at Ahoy@SeabookApp.com so that I can take very immediate action to help out. Thanks so much.
