What it does

Everything your logbook should be

No paper. No spreadsheets. No subscription. Just a clean interface that stays out of the way and does its job.

Fuel & charging

Log every fill-up and charging session. Track cost per litre, cost per kWh, and exactly where your money goes.

🚗

Fleet in one place

Manage every vehicle you own — BEV, PHEV, hybrid or petrol. Switch between them in seconds.

📊

Real analytics

Efficiency trends, cost breakdowns, monthly spend — visualised clearly so patterns are obvious at a glance.

🔒

Your data, your server

Self-hosted. Nothing leaves your machine unless you decide. No subscriptions, no tracking, no data brokers.

How it works

Simple by design

01

Add your vehicles

Register each car, van or bike with its powertrain type. Journii adapts efficiency units automatically — L/100km for petrol, kWh/100km for BEV.

02

Log as you go

After every fill-up or charge, open Journii and enter the amount, price, and odometer. Takes about 20 seconds.

03

Watch the trends

The stats workspace shows monthly cost trends, efficiency over time, and a breakdown across your whole fleet — all automatically.
