Selling your boat someday? Keep the service history a buyer asks for (dates, engine hours, parts and costs) and share it as one clean PDF record with Boat Pro. Good Trim helps you keep a durable maintenance record for your boat. See what is overdue or coming due, log the work you complete, and keep the details you may need later. TRACK BOTH CLOCKS Set maintenance intervals by date, engine hours, or whichever comes first. Update meter readings and see the threshold behind each due state. Meter replacement keeps the older readings and the accumulated hours in context. KEEP THE SERVICE HISTORY Record dates, readings, provider, parts, costs and notes. Attach photos, receipts, manuals and other documents to equipment or service entries. KEEP YOUR RECORD WITH YOU Good Trim works offline and stores your records on your iPhone. Create a complete backup, restore it when needed, and export linked CSV files. There is no account to create. START FREE, UPGRADE ONCE The free app includes one vessel, the full maintenance ledger, up to 10 attachments, backup and restore, and CSV export. Boat Pro is a one-time purchase that adds unlimited vessels and attachments, PDF reports and richer history filters. No subscription. Good Trim is an owner-entered maintenance record. It is not a substitute for a professional inspection or the manufacturer's service guidance.
