Before you download
What is included in the download?
All 482 cards across ten sets, including bundled illustrations and signal demonstrations. There is no subscription, advertising or in-app purchase.
Can I use it offline?
Yes. The cards, pictures and signal demonstrations are bundled in the app. Study progress stays on your device. Optional support and website links open outside the app.
Is this the same as the Compass Revision course app?
Flash Cards is a separate paid app for recognition and recall. The Compass Revision course app offers guided lessons, questions, mocks and account-based course access. A website or course-app purchase does not include this separate Flash Cards download, and Flash Cards does not unlock those courses. Progress is separate and does not sync between the apps or website.
Which devices does it support?
Flash Cards is available for iPhone and iPad running iOS or iPadOS 16.4 or later.
Do I need all ten sets for my course?
The sets span different courses and regions. Choose the topics your syllabus requires, including the correct IALA buoyage region. This is an independent revision aid, not an official course, certificate or substitute for current rules and practical training.
Keep a little nautical revision in your pocket.
All ten sets, ready offline. Available now for iPhone and iPad.
