Journii - Vehicle Logging & Analytics

Track Fuel, Charging & Costs Across All Your Vehicles

Beta — In Active Development

Journii is a Europe-focused vehicle logging platform that helps you track fuel fill-ups, EV charging sessions, mileage, and spending across multiple vehicles. With powertrain-aware analytics and privacy controls, it gives you clear insights into your driving costs and efficiency — whether you drive petrol, diesel, hybrid, or fully electric.

Features

Smart Fuel Tracking

Log every fill-up with litre amounts, pricing, and odometer readings. Journii calculates consumption trends and cost-per-kilometre automatically.

EV Charging Sessions

Track charging sessions for battery and plug-in hybrid vehicles — energy in kWh, pricing, and station details, all in one place.

Comprehensive Analytics

A full analytics workspace with monthly trends, vehicle comparisons, efficiency benchmarks, cost breakdowns, and resource mix charts.

Multi-Vehicle & Powertrain

Manage ICE, hybrid, plug-in hybrid, and fully electric vehicles side by side — each with powertrain-aware tracking and analytics.

Personalised Settings

Set your locale, timezone, currency, and preferred consumption format (L/100km, km/L, kWh/100km). Choose how precisely your location is stored for privacy.

Modern & Responsive

A clean, warm-neutral interface with teal accents. Desktop sidebar navigation on larger screens, sticky bottom nav on mobile.

Built With Modern Technology

Journii runs on a Django 5 REST API with a SvelteKit 2 frontend. Chart.js powers the interactive visualisations, and the whole stack is designed for responsive, privacy-conscious use across desktop and mobile browsers.
