Study Rules of the Road Offline, and Sync Progress Between iPhone and iPad
TL;DR
Everything is bundled, so it works at sea, at the dock or in the yard. iCloud sync is optional, off by default and runs through your own iCloud account.
Works anywhere
1,200 questions, 83 diagrams and the complete rule text are inside the app. There’s no signal needed, ever.
No account
Nothing to sign up for. No ads. No subscription and no in-app purchases.
Sync if you want it
Turn on iCloud sync to keep your progress aligned between iPhone and iPad. It is off by default, and it runs through your own iCloud account.
Comfort
Dark appearance is the default, and there’s an extra font size step above the system setting if you want bigger type.
FAQ
