Compass Revision Flash Cards

About

Compass Revision Flash Cards is a simple nautical recognition and recall app. Choose a set, tap a card to reveal its answer, then swipe right for Got it or left to practise it again. You can also sort a card without flipping it first. Return to a full set or focus on cards that need more practice. Cards, illustrations and signal demonstrations are bundled for offline study. Your study progress stays on this device. There is no account, subscription, advertising or in-app purchase: the included sets come with the paid download. The sets span different courses and regions. Your own syllabus may require only some of them. This is an independent revision aid, not a substitute for current official rules, a training course, or safe navigation practice. Compass Revision's separate course app and website offer guided learning if you need more than flash-card practice.
