Why it matters
Running costs add up quietly. A missed oil change, an expired registration or a slow drop in fuel economy each costs real money. Odo keeps the record and does the arithmetic, so you notice early.
Fill-ups in seconds.
Point your camera at the pump and Odo reads the volume, price and total, checking that the numbers add up before you save. Nearby stations are suggested automatically, and the odometer is pre-filled from your recorded trips.
- Scan the pump or charger display
- Enter any two of volume, price and total; the third is worked out
- Nearest station picked automatically
- Odometer suggested from your last reading plus trips since
- Gasoline, diesel, LPG, CNG, hydrogen, electric and custom fuels
- Prices in pence per litre for UK drivers
Fuel economy you can trust.
Economy is calculated full tank to full tank, the most accurate method, with partial fills folded into the next full one. Plug-in hybrids track fuel and electricity separately.
- MPG (US and UK), L/100 km or km/L
- kWh/100 km, mi/kWh, Wh/km or MPGe for electric vehicles
- Economy, price and monthly cost charts
- Cost per mile or kilometer for every fill-up
Service reminders that count from the last service.
Set a reminder by date, by mileage, or both, measured from when the work was last done. Complete it and the next one is scheduled automatically.
- 30 service types plus your own
- Reminders by date, odometer, or every so many months or miles
- Notifications, and date reminders in your Calendar
- Full service history with costs by type
Documents and every other expense.
Keep insurance, registration, inspection and more with their expiry dates, and get reminded as many times as you like before they run out. Tolls, parking and repairs go in the same place.
- 13 document types, with photos or PDFs attached
- Expiry reminders and Calendar events
- Mark a document renewed and the cost is logged for you
- Expenses by category with month and year comparisons
- Up to 10 receipt photos or PDFs on any entry
- Unlimited vehicles, with VIN lookup for make, model and year
