Tankblick Navegação GPS e Mapas app para Android descrição
Current prices for E5, E10 and diesel at German filling stations — fetched quickly, with nobody looking over your shoulder.
What Tankblick does
- Search nearby, with price, distance and open/closed status
- Favourites for the stations you actually visit — all refreshed in a single request
- Detail view with all three prices, the address and opening hours
- Navigation with the app of your choice: Organic Maps, OsmAnd, or whatever else you have installed
- Keeps working offline, and says honestly how old the prices on screen are
What Tankblick does not do
No account. No tracking, no analytics, no ads. No background requests.
The app talks to exactly one server: creativecommons.tankerkoenig.de. Your location leaves the device only as a coordinate pair in a search you started yourself. Favourites, settings and prices stay local, and price history is deleted after 30 days.
You need your own API key
Tankerkönig issues keys per person, and a key hidden inside the app could be extracted anyway. Register for free at onboarding.tankerkoenig.de — first name, last name and email address are required. Keys are reviewed by hand, which can take a few days. A demo key is available in the app for trying it out.
Your key is encrypted with AES-256-GCM in the Android Keystore and excluded from cloud backup.
