What it does

Your machines

Add boats, outboards, generators, tractors and other equipment with make, model and serial or hull number.

Hours and fuel log

Log engine hours or odometer readings and fuel. Consumption is only calculated between full tanks.

Service intervals

Set maintenance by hours or months, whichever comes first, and see what is due soon.

Service records with photos

Record what was done, by whom and what it cost, with receipt and part photos.

Checklists

Ready lists for departure, winterising, season start and generator tests, plus your own lists.

Documents

Keep insurance, registration and warranty with their expiry dates and get reminded before they run out.

PDF reports and costs

Export the full maintenance history as a PDF for a sale, and see costs by month and per engine hour.

Reminders and widgets

Optional service-due reminders, plus Home Screen and Lock Screen widgets.

Backup and export

Back up to a file, restore it on another iPhone, and export to CSV.

Free and premium. Free: one machine with its maintenance plan, service history, hour readings, fuel log, the ready checklists, reminders and one photo per service. Tacho Pro is an auto-renewing weekly, monthly or yearly subscription with a free trial, and adds unlimited machines, PDF reports, cost charts, documents with expiry reminders, your own checklists, unlimited photos, all Home Screen and Lock Screen widgets, and backup, restore and CSV export.
