Everything about your vessel. One place. Finally simple.
Offline-first. Built for the moment the signal dies. Works at anchor in the Abacos. Always.
theONE replaces a dozen apps, spreadsheets, and group texts with a single iOS app — telemetry (NMEA 2000 ready), crew, planning, playbooks, and maintenance. Captain-grade, for power vessels 40 feet and up.
iOS & Apple Watch · NMEA 2000 ready · NOAA weather, tides & charts (US coastal)
Every critical feature was designed to work with zero connectivity — logging, maintenance, stowage, crew access, and the emergency tools you hope you never open. No marina Wi-Fi. No cloud round-trip. No waiting.
Forty miles from the nearest cell tower is a terrible time to discover your boat app needs the internet.Capture any note or photo on the fly, then route it to maintenance, a vendor, or the observation log when you're back at the table.
File a float plan in under a minute — departure, destination, souls aboard, expected return — sent to dockmasters or shore contacts.
Eyes on the water. Log an MOB pin, watch change, or logbook entry hands-free via Siri.
One tap for MOB pin (GPS timestamped), USCG contacts, and DSC radio procedure.
Scan, store, and retrieve manuals and certificates — offline.
NOAA tide data in Today view. Exportable vessel briefing — one-tap PDF for relief captains, owners, and pre-departure review.
Maintenance templates for the major brands — Volvo Penta, MAN, CAT, Cummins, Yanmar, Onan, Northern Lights, MerCruiser, Seakeeper, Side-Power, and Lewmar.
Underway heading, SOG, depth. Tanks and MOB on the wrist.
Active leg, ETA, and telemetry in the Dynamic Island.
Arm at the GPS fix. Drag alert if the boat moves outside your radius.
Wi-Fi passwords, marina codes, gate access. Face ID locked.
See how today's observation connects to last summer's incident.
Well over 100 in-app help articles, and growing. One tap from any screen.
By word, not by memory. Spare impeller, flare kit, guest towels, the good corkscrew. Type it. Find it. Know which locker, which shelf, which bin.
Tag any item to a locker, shelf, or bin. Photos optional. Works offline.
Plain-word search across every item on the boat. No codes. No categories to memorize.
Guests and crew can look up where things live without calling the captain.
Log it yourself on a schedule you set, or connect theONE directly to your NMEA 2000 network and let it log automatically at whatever interval you choose. Same data. Same place. Your call on how it gets there.
Daily, weekly, every engine hour, every trip. theONE prompts the crew at the right moment. Tap, confirm, done.
Engine hours, fuel burn, depth, temps, voltages, and tank levels at the interval you set — one second to one hour. Offline-first. Syncs when you have signal.
Switch any data point between manual and automatic at any time.
Every issue, observation, maintenance log, and hour reading feeds a causal engine that watches your boat for patterns — and tells you when a pattern that ended badly last time is starting to repeat.
Surfaces patterns in your boat's systems and weights the likelihood of what needs attention next: "this fault chain matches your July 2024 alternator failure."
Catches the obvious: service intervals, burn-rate anomalies, stale logs.
Ranks the next 72 hours so you know exactly when to leave.
Every warning is traceable. Tap "why?" and theONE shows you the evidence — the engine hours, the fuel burn, the last three trips, traced to the cause. No black boxes. No magic. Just your boat, finally remembering everything.
A read-only snapshot of your boat's state. For surveyors and relief captains.
Per-leg pre-departure summary. Tide at ETA, crew aboard, open items.
Post-cruise summary in one PDF.
Official chronological log with watch intervals.
Maintenance posture, recent service, vendor sign-offs. For use with insurance — not an insurance-approved document.
A weekly one-pager for the owner who isn't aboard.
A maintenance entry isn't a lonely receipt. It sits inside the full run history — hours, conditions, anomalies, observations — so you can see what actually led up to it.
Every log, every reading, every Jot, every photo — connected to the moment it happened. Nothing floating in isolation.
When a surveyor, buyer, or insurer asks what happened, you've got more than a stamp on a page. You've got the run that came before it and the run that came after.
Jump from the engine room to the guest list to a vendor invoice without backing out of anything.
Mid-task idea? Capture it, act on it, come back. theONE remembers where you were.
Search by word. Tap by intent. The app bends to how you think, not the other way around.
Captains and owners invite the rest of the crew with a tap. Each person gets exactly the access their role needs — nothing more, nothing less. Access works offline.
Full access. Sets the vessel, invites everyone, owns the data.
Runs the boat day-to-day. Plans trips, logs runs, manages maintenance.
Handles schedules, vendors, and paperwork. No helm-side noise.
Logs hours, completes checklists, sees the trip plan and weather.
Read-only on systems plus write access to the jobs they're assigned.
Trip-scoped view: itinerary, safety brief, where things are. Expires when the trip ends.
The first 50 captains get early access to theONE before public launch and a direct line to the team. In return we ask for honest feedback from real trips — including the ones where the signal disappears. Request your spot below.
