VesselTwin: Boat Maintenance

Logbook, reminders & manuals

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Private by default: we don't sell your personal information, and the AI providers we use can't train on your data. Log work, find manuals, and ask your boat. Keep your boat's maintenance log, manuals, parts, and documents in one private place, see what's due next, and ask questions answered from your own records. Your records are private by default. We don't sell your personal information, we don't send your boat records to advertisers, and the AI providers we use can't train their models on your data. You can export or delete your account at any time. Use VesselTwin on iPhone and iPad while work is happening. Capture a photo at the dock, file a document in the yard, record a measurement onboard, or add a maintenance note before the details disappear. Capture drafts save locally first and sync when you are back online. KNOW WHAT'S DUE, FIND WHAT YOU NEED • Today shows what's overdue and what's coming up next. • My Boat organizes work, parts, documents, and photos by area, so a job lives where you expect it. • Keep a job as a to-do and find it again from My Boat, with To Do and History tracked separately. • First use offers a clear starting point: save a receipt, remember a job, or find a manual. Included manufacturer manuals show up even before you upload your own documents. KEEP THE BOAT RECORD TOGETHER • Maintain the boat profile, specifications, measurements, equipment, parts, and documents in one place. • Record maintenance and service history with the context future owners, operators, and technicians need. • Track expenses and see service costs alongside the work they describe. CAPTURE FROM THE FIELD • Add photos, documents, measurements, maintenance notes, and issues from a focused capture flow. • Scan multi-page documents and recognize equipment serial numbers on device, then review before saving. • Keep working through unreliable marina connectivity with a local-first capture inbox. • Review, retry, and finish uploads when the connection returns. USE THE NATIVE TOOLS AROUND YOU • Glance at Next service and Readiness from private, offline Home Screen widgets. • Ask Siri to open a boat, begin a review-first capture, or read the next saved service date. • Find cached boats and record titles in Spotlight without indexing private notes or identifiers. FIND THE RIGHT CONTEXT • Search your private vessel records, starting from the boat you're already looking at. • Browse public boat-model knowledge and community experience. • Keep useful provider contacts near the vessel record. ASK YOUR BOAT • Ask questions in VesselTwin and get grounded answers from saved records, with sources you can open. • Reopen a saved Ask or Troubleshoot answer any time without asking again. • Troubleshoot walks through a symptom against this boat's manuals and service history. • Continue in the assistant you choose. You can also connect ChatGPT for basic, read-only boat questions; Owner Pro supports Claude and deeper questions across your records. • Private document text, notes, costs, identifiers, and stored locations stay off unless you explicitly allow access. • Optionally let a connected AI app propose notes, checklists, maintenance entries, and measurements. Every proposal waits in your Inbox until you accept it. COMMUNITY CONTROLS Share or publish only what you choose. Report community content and block members at any time. VesselTwin is built for boat owners and operators who want the boat's real history to be easier to capture, understand, and carry forward.

  • This app hasn’t received enough ratings or reviews to display an overview.

Show me where, easier lists, and safer sign-out. • Show me where: add private photo guides that mark where things are on your boat, with several labelled callouts on each photo. • Easier to read: lists wrap long names instead of cutting them off, and buttons are larger and easier to tap. • Signing out now warns you before it discards anything you haven't sent yet, and unsent drafts show up as Unsent on Today and in your lists. • My boat has a new All records shortcut, so Expenses and Parts are only two taps away. • Appearance follows your phone's light or dark setting by default.
