Sparkilo
Find a better fuel stop. Understand what each kilometre costs.
Sparkilo brings fuel-price comparison, route searches, fill-ups and trip records together in one free,
open-source app. It is for everyday drivers, cross-border commuters and road-trip planners who want to
connect the price at the pump with what running their own car actually costs.
Start with a nearby search. Add a fill-up log when you want to track consumption.
Connect a compatible OBD-II adapter when you want engine data alongside your trips.
The core app works without an account; cloud sync is optional.

Get Sparkilo
The libre (F-Droid) build leaves out Google Play Services, ML Kit and the Sentry SDK. Receipt and
pump-display text recognition is therefore unavailable in that build; manual entry and QR-code scanning
remain. Read the installation guide before switching between builds, because their signing keys can
differ.
What you can do
Choose your next fuel stop
- Compare nearby stations in a list, on a map, or in a table with one column per fuel grade.
Each result names the data source it came from.
- Search along a route, including across a border into supported countries.
One profile per country holds the preferred fuel for that leg.
- Keep useful stations close with favourites, price alerts (per station or within a radius) and
price history. History builds from the prices the app has collected; "best time to fill" hints are a
heuristic over that history, not a forecast guarantee.
- Find EV charging locations through Open Charge Map, with connector, power and the status Open
Charge Map reports. That directory is not a live occupancy feed and carries no guaranteed tariffs.
Understand your running costs
- Log fill-ups and vehicles by hand, or read a receipt or pump display with on-device text
recognition on the Google Play and iOS builds. Check the extracted values before saving.
- Follow consumption and cost per kilometre, tank level and range, compare the fuels you have
used, and price a planned journey with the fuel-cost calculator.
- Keep your records useful with trip history, service reminders, data export and optional
TankSync across devices.
Explore your driving
- Record trips with GPS alone, no adapter needed: route, distance, speed and an estimated
consumption.
- Add a compatible ELM327 OBD-II adapter to enrich trips with the engine signals your vehicle
exposes, such as fuel rate, RPM, throttle or load.
- Review how you drive through trip summaries, a route coloured by efficiency, and coaching hints.
Adapter compatibility, available signals and background recording depend on the vehicle, the phone,
the operating system and the build.
Choose the Basic, Medium, Full or Custom feature preset to keep the app as simple or as deep as you
need. The interface is available in 23 languages.

Coverage you can plan around
Fuel data comes from government open data and, where no national feed exists, from retailer feeds.
Coverage, fuel grades, station details and update frequency vary by source. Cached results stay
readable offline; fresh prices need a connection and a reachable provider.
The code contains 17 country integrations. Thirteen are offered in the app's country selection:
