Would be good to have settings to apply Buoyage A & B & combined. ### 3/5 — Good app *2023-03-10, version 4.2.6* It’s ok but you need to upgrade to hear sounds. ### 4/5 — Utile *2022-11-11* Bien pour réviser ### 3/5 — Good Study Tool *2022-05-26, version 4.2.6* I’m taking a course in seamanship and this is a useful study aid but it needs to stop prompting me to review it every time I switch screens so I can actually get some studying done! ### 4/5 — Fait le job *2022-02-01* Une appli simple et ludique, pratique pour réviser ### 3/5 — . *2021-10-02* Too many requests to review the app. ### 4/5 — Good one for quick reference *2021-08-10* Very useful for quick revision but most of the features are kept reserve for the paid version which is a bit annoying ### 4/5 — Utile *2020-10-23* Très bon app pour se rappeler ... ### 4/5 — App asking for feedback too many times *2020-08-25* Too many times asking for feedback, otherwise app ok ### 4/5 — Good info *2020-08-12* Stop asking me to review the app every two minutes. Otherwise ok ### 3/5 — Search feature *2020-06-04* Great little app with a lot of relevant information at one’s fingertips. I wish it had a search feature. ## Most critical reviews (10 lowest-rated) ### 1/5 — Broken *2026-03-06, version 5.3.1* The app isn’t working. The first ad loads then wont clear to allow you into the material. ### 1/5 — Wouldn’t recommend *2025-09-05* Unfortunately this app has turned into a money grab with its subscription. Originally paid the full price for the app, but now it prompts me to subscribe, have tried to contact, with no response. Would look elsewhere for training guides as you will easily find better value. ### 1/5 — Swamped with Ads *2025-07-12, version 5.1.7* Absolute rubbish now as it is swamped with LONG advertising. I have deleted it. ### 1/5 — Sold Themselves Out To Google *2025-04-07* Never use to have ads. Can’t use it because the ads are just so thick and constant. It was good but not now. ### 1/5 — Pro lifetime withdrawn, scam *2025-03-19* Paid for lifetime pro app as have others. Recommended it to others as it was a great app. Now asking for annual subscription which is disappointing and probably illegal. Gone from 5 to 1 star. ### 1/5 — Scam *2025-02-23* I paid for the pro version for lifetime access, Marinus has now changed this to a subscription model, requiring me to pay yearly for access, complete scam. Great app, terrible business ### 1/5 — Voleur *2025-02-22* Déjà acheté la version pro et vous me l’avez retiré vous êtes des voleurs ### 1/5 — Pro no longer works and full of ads *2025-02-11* Pro purchase gone, ### 1/5 — Bad business model *2025-01-21, version 5.0.2* I bought the pro app few years ago. Now they want me to subscribe. ### 1/5 — Nul de chez nul *2023-06-26* 1 étoile car on peut pas mettre moins. Tout est bloqué , il faut la version pro pour s’en servir. Autant la mettre payante d’entrée j’aurais pas perdu mon temps aller hop désinstallation immédiate de cette daube. ## Most praised reviews (10 highest-rated) ### 5/5 — Vraiment très bien *2025-04-06, version 5.1.7* . ### 5/5 — awesome *2025-03-01* good for learning ### 5/5 — Parfait pour les révisions du bac *2023-05-23* Appli simple et ludique qui résume parfaitement les bases de la nav :) ### 5/5 — Simple efficace *2023-02-14* Super pour la mémoire ### 5/5 — Review *2022-09-07* App is good as a beginners tool. But full app is not cheep. ### 5/5 — Good rating *2022-02-04* It’s a great app with a lot of information in it and so easy to use ### 5/5 — Great value for money considering it’s free *2021-05-04* This app has really helped me with my yacht courses ### 5/5 — Great app *2021-01-31* Always helpful and superb interface ### 5/5 — Overall good *2020-07-20* Overalls good information ### 5/5 — Brilliant! *2019-12-18, version 4.2.6* Totally brilliant thing to have on your phone at sea! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
