Rather, you have to go to the website and do your quizzes there, which for me defeats the point of an app. ### 5/5 — A valuable resource. *2019-05-01* I had cause to need this info recently when out in a near gale force wind. Brilliant - I had it on my iPhone in a water proof case, and could refer to it without leaving the (very wet) helm - much better than a dash to the chart table to thumb through a book! Thank you! ### 1/5 — Crap *2019-02-28* Does not work, when right answer is given says wrong. ### 5/5 — Good app *2017-11-29* Great at a glance quick reference, which is essential when at sea. ### 5/5 — Recommended - have also bought your other two apps *2017-11-29* Very useful app, looks great - really good info, well presented. I have also bought your other two in the series! Recommended. ### 1/5 — Not updated with latest buoyage *2017-01-09* Emergency wreck mark is missing & new danger mark is of wrong colour ### 1/5 — Not worth the time or money *2015-11-13* The app is extremely basic, the two quizzes are just basic flash cards, no actual scenarios or buoyed channels. ### 1/5 — Misrepresentation at its best *2015-03-03* Quickest app deleted after buying to date. Pics show well, app is nowhere near the presentation. Best avoided. Big opportunity for someone to create a simple reference app in this category. Thought I found one but alas, they found my money only... ## Frequently asked questions about IALA Buoyage & Lights ### What is IALA Buoyage & Lights?
