Watabook: Car Log & Fault Code

Watabook is the car logbook that also tells you what's wrong — in plain words.

No dongle. No account. Works fully offline. No ads, ever.

UNDERSTAND A WARNING LIGHT
• 36 dashboard symbols — red, amber, green and blue — with what each one means and what to do
• Type or photograph an OBD-II fault code and get a plain-language explanation
• "Can I keep driving?" — safe / gently to a garage / stop now
• Likely causes, a rough cost range, and whether it's a DIY job
• Read it aloud, or ask a follow-up in your own words
• The offline fault-code dictionary and every symbol work with zero signal

NEVER MISS A SERVICE
• Oil change, filters, brake fluid, tyres, timing belt, insurance renewal, inspection
• Remind by date, by mileage, or whichever comes first
• Recurring reminders that roll forward when you mark them done

ONE LOGBOOK PER CAR
• Every service, fuel fill-up, expense and note — with the odometer, cost and photos
• Fuel economy and cost-per-kilometre worked out for you
• See what your car really costs, this year and over its life

KEEP THE PAPERWORK
• Registration, insurance and receipts in one place, on your phone
• Export everything as CSV any time — your data is never locked in

Free: one vehicle, unlimited log entries, date & mileage reminders, the full offline
fault-code dictionary and warning-light reference, CSV export.

Watabook Pro adds unlimited vehicles, AI "explain simply" answers and voice, smart
recurring reminders, the document vault with expiry alerts, a printable maintenance
history PDF, and cost analytics. One clear price, 7-day free trial, cancel anytime.

AI explanations are general information, not a diagnosis — always have safety-critical
faults checked by a professional.
