Do I have to add a vehicle first?

You already have one

No — creating your account created a vehicle too. It is called My Car, it is already your default, and drives are logged against it from the very first trip. An account always keeps one vehicle: the last one cannot be hidden.

Making it yours

Rename it to something you will recognise in a list. Make, model, year and type are optional:

1. In OdoTax, open Settings → Vehicles
2. Tap your car — My Car, until you rename it
3. Change the Name, and add make, model, year or type if you want them
4. Tap Save

If you drive more than one car

Add a second vehicle when you drive more than one car or van for work — the report then keeps the log per vehicle. Default vehicle decides which one a drive lands on when nothing else says:

1. In OdoTax, open Settings → Vehicles
2. Tap + at the top right
3. Give it a name, or a make and model, and switch Default vehicle on if it is the car you drive most
4. Tap Add vehicle

On an iPhone, a Shortcuts automation can tell OdoTax which car you got into, so its drives go on it: see Can OdoTax tell my cars apart by Bluetooth?

The same screen links the car’s Bluetooth, so its drives go on it by themselves — see Can OdoTax tell my cars apart by Bluetooth?
