Cheapest fuel, every trip, every deadline — for every car you own.

Available in English, Italiano, Français, Español, Deutsch
How it works
Three steps. No account, no setup wizards.
Install, pick your car, start using it. The OBD-II adapter is optional — everything else runs phone-only.
2 — Use it phone-only
Look up fuel-station prices, log refuels, record GPS trips, set deadline reminders. No adapter, no extra hardware — your phone is enough.
3 — Plug in OBD-II (optional)
Add any ELM327 or OBDLink (Bluetooth Classic, BLE or Wi-Fi) and you also get a live dashboard, true fuel-used on trips and a DTC code reader.
Fuel
The cheapest pump, in the country you are in
Five live registries, one map. Currency is converted on-device using ECB rates — no third-party tracker.
Stations near you
Map and list view, filter by fuel type (Diesel, Petrol 95/98, LPG, CNG, AdBlue), distance radius and brand. Tap a station for prices, last update timestamp and turn-by-turn navigation in your default maps app.
Country & regional trends
Average price for each fuel type by country and region, refreshed daily. Flag which side of the average a station sits on — green when below, red when above.
Refuel log
Log full or partial refuels in seconds: litres, total cost, odometer, station. Per-vehicle stats: real consumption (km/l, l/100 km, mpg), cost per kilometre, monthly spend chart.
Trips
Every drive, recorded the way you'd record it yourself
GPS-only mode works without an adapter. With OBD connected you also get true fuel-used and engine-hour stats.
Live recording
Foreground service keeps the GPS lock alive when the screen is off. Teleport detection rejects bad fixes. Auto-stop on engine off (when OBD is paired) so you don't end up with a 4-hour trip after you parked.
Trip detail & map
Full route on OpenStreetMap tiles, average and max speed, distance, duration, fuel used (real or estimated), litres / 100 km, cost based on your last refuel. Edit, rename, delete or merge trips.
GPX export & sharing
Export any trip as a GPX file you can open in Google Earth, Strava, Komoot or your favourite mapping tool. Share the route summary as text or as a static image.
Ownership
Everything a logbook should be — searchable
Per-vehicle records that survive phone changes thanks to the ZIP backup.
Maintenance log
Service entries with date, odometer, workshop, cost and free-text notes. Predefined types (oil, filters, brakes, timing belt, tyres, coolant, transmission, clutch) plus custom types you define.
Deadlines
Road tax, insurance, MOT/inspection, periodic service. Notifications fire 30, 7 and 1 day before — repeat or one-off, your choice.
Documents vault
Attach photos or PDFs of registration, insurance card, last inspection. Stored encrypted in app-private storage so other apps cannot read them.
Tyre sets
Track winter and summer sets independently — fitting date, odometer, current km on each set, brand, dimensions and DOT week. Reminder when a set crosses 40 000 km.
Multi-vehicle
One app, your whole garage
Each car keeps its own settings, history, refuels, deadlines and trips.
Vehicle profiles
Add as many cars as you want. Switch with a tap from the home screen. Profiles include displacement, fuel type, tank capacity, custom photo and a colour tag.
Per-vehicle settings
Units (km/mi, l/100 km / mpg / km per litre), currency, idle RPM threshold, target consumption — all stored at the vehicle level so a switch carries the right defaults across the whole UI.
Backup & restore
Settings → Export creates a single ZIP with the SQLite database and preferences. Drop it on a new phone, hit Restore, you are back exactly where you were. Auto-backup runs weekly to the folder of your choice.
Bonus · OBD-II
Plug in an adapter and your phone becomes the dashboard
Everything in this section unlocks with an ELM327 / OBDLink adapter — strictly optional. The rest of the app works without one.
Live cluster
Three skins — Classic gauges, Sport digital, Retro LCD. RPM, speed, coolant, intake, throttle, MAF, MAP, voltage, instant L/100 km. Fullscreen landscape mode for the dashboard mount.
DTC reader
Fetch stored, pending and permanent fault codes (modes 03 / 07 / 0A). Each code shows a plain-language description in your language. Clear codes with a confirmation step that warns about emissions readiness reset.
Read history
Every connection is logged with timestamp, VIN, codes found and PIDs sampled. Useful before a workshop visit so you arrive with proof, not a vague description.
Android Auto
On the in-car display, where it belongs
Built with the official Car App Library — passes Google's distraction-optimisation rules.
- Live OBD cluster optimised for car displays (large fonts, glanceable layout)
- Quick fuel-station search with one-tap navigation
- Refuel logger with voice-driven cost / litre input
- Trip status panel — recording, distance, fuel used
- Deadline alerts surface as in-car notifications
- Bluetooth status and adapter health visible at a glance
- Currency- and unit-aware cards (no metric/imperial surprises)
- Works wired or wireless, no extra setup beyond first-run consent
Privacy
Local-first means your data stays on your phone
We still publish a privacy policy because Google Play and the GDPR require us to be explicit, and because public price registries see your IP when you query them. No analytics, no ads, no account.
- No account, no sign-in, no telemetry pings.
- All data lives in app-private SQLite storage. Uninstall removes everything.
- Public APIs (MIMIT, Roulez-Eco, ECB, OSM tiles) are queried directly from your phone — they see only an IP, never a profile.
- Backups are local files. You decide where they go.
Install free, no adapter required
Pick your vehicle from the bundled database and you're already running fuel search, trip recording and the maintenance log. Add an ELM327 / OBDLink later if you also want diagnostics.
