Cornamusa01 / The boat
Keep its history with it.
Hull, engines, GPS and onboard equipment. Maintenance, service, fuel, hours and expenses. Keep a record you can correct and export, with a separate account for each family or crew member.
For your boat. And the people aboard.
Your boat.
All together.
The manuals, maintenance, trips and little details that make a day on the water easier. Cornamusa keeps them together on your iPhone, shared with the people you choose.
iPhone first · In private testing · US launch planned
The first release
Less hunting for information.
More knowing where it is.
02 / The trip
A checklist that’s actually yours.
Create your pre-trip and post-trip lists in Settings, then change them as you learn your boat. New trips start with fresh checkboxes; the old trip keeps its history.
Optional marina reminders use this iPhone’s location. Checklists also work without location permission. Physical arrival and return validation is pending.
03 / The manuals
Right manual. Right where you need it.
Add your hull and equipment details to request suitable manufacturer manuals. Read and search matched PDFs inside the app. Download individual manuals before a trip, then remove their offline copies when you’re back.
Some equipment needs a more specific model or year before a manual can be matched. Text search depends on the PDF’s text; scanned pages may not be searchable.
04 / The paperwork
Paper on the dock. PDF on the boat.
Use the iPhone camera to scan a receipt or document into a private PDF. Attach a receipt to an expense and share it with authorized boat members. Storage and file-access limits keep the plans predictable.
Up to 5 MB per PDF. General photo and video uploads aren’t offered.
Start with the boat. Add what you need.
One app, with room to grow.
Docklift, inside Cornamusa.
The plan is to bring the existing Docklift feature into the first release, with compatible hardware, pairing, separate lift permission and a paid subscription.
A command acknowledgement tells you a request was received. It does not tell you that the lift moved, stopped or reached a position.
About DockliftThe boat’s data, connected.
Telematics will build on compatible NMEA 2000 hardware. NavLink boat testing is being prepared; live data, supported readings and the eventual plan will follow that testing.
This feature is not available in the current release. Cornamusa does not currently collect automatic boat telemetry or provide emergency monitoring.

Pay for the extra storage you need.

Storage is total capacity. Upload and file-access allowances are shared rolling 31 UTC-day limits; upgrading does not reset usage. No automatic overage charges. Paid plans renew automatically until cancelled in your Apple account. After expiry, existing PDFs remain, free access limits apply, and new uploads pause if the boat is over its allowance. Manufacturer manual downloads are separate from private PDF storage. Docklift hardware and access are separate.
A few useful answers
Before you come aboard.
Can my family use it?
Yes. Each person signs in with their own account, and the owner controls access to the boat. You don’t need to share an Apple ID or a password. Lift operation requires separate authorization.
What works without a signal?
Manuals you have already downloaded can be reopened and searched on your iPhone. Online manuals, boat record syncing and account features need connectivity. Cornamusa does not queue hardware commands for later delivery.
How do marina reminders work?
You choose a marina and allow notifications, Always Location and Precise Location for background reminders. They follow this phone, including driving, and may be delayed by iOS. They do not confirm that your boat left or returned. Your editable checklists work without those permissions.
Can I download the app today?
Cornamusa is currently in private iPhone testing. The first public launch is planned for the US App Store. There is no public download or signup on this website yet.
What happens if I cancel storage?
Your Apple subscription stays active until its paid period ends. Existing PDFs remain; free limits apply afterward and new uploads pause if the boat exceeds free capacity. Deleting the app or account does not cancel an Apple subscription.
