Do I need an account?
No. Rhumb works out of the box — open it and you are looking at the chart. Markers you create sync through your own iCloud account, not through a Rhumb account.
Why is my course or speed empty?
Course over ground (COG) and speed over ground (SOG) come from GPS and need the vessel to be moving. Both readouts stay blank until there is a GPS fix while underway.
What does Rhumb Premium include?
Rhumb Premium adds automatic sea routes and average speed over ground on the instrument screen. Background GPS keeps the averages complete while the app is in the background. It starts with a one-week free trial, then costs $2.99/month or $19.99/year.
How do I cancel the subscription?
Go to Apple Account settings → Subscriptions on your iPhone or iPad and cancel Rhumb Premium there. Deleting the app does not cancel the subscription.
Can I use Rhumb as my main navigation tool?
No. Rhumb is a passage-planning aid, not a substitute for official nautical charts. Always verify your route against official charts before you sail.
