mitch.brook@icloud.comAll prices come directly from official government fuel price APIs. We don't use crowdsourced or scraped data — every price you see is reported by the station to their state government. Sources include:
Tank refreshes prices from government feeds approximately every 30 minutes. The actual frequency of station price changes depends on the retailer and state regulations — some states require updates within 30 minutes of a price change, others may differ.
Tank currently covers New South Wales, Queensland, Tasmania, and Western Australia. These are the states with publicly available government fuel price APIs. More states will be added as their data becomes available.
Tank uses your approximate location only while the app is open to centre the map on nearby stations and calculate distances. Your location is never stored, sent to a server, or tracked in any way. You can also browse the map manually without granting location access.
Australian fuel prices follow predictable cycles — prices rise sharply then gradually fall over a period of days or weeks. Tank analyses recent price data to determine where you are in the current cycle. If prices are near the bottom, it recommends filling now. If they've just spiked, it suggests waiting for them to come down.
Yes. Tank is completely free with no ads, no in-app purchases, and no premium tier. The fuel price data comes from free government APIs, and the app has no tracking or monetisation.
