The situation

Fuel prices in Germany change several times a day, and two stations in the same town are often several cents per litre apart. Many well-known apps are cluttered with ads, slow or impractical when you are behind the wheel.

The goal was a lean app that instantly shows what matters: which station nearby is cheapest, whether it is open and how to get there with a single tap.

What we built

The solution.

Prices nearby

Live prices for E5, E10 and diesel from Germany's official market transparency unit – with radius, sorting by distance or price and an open/closed indicator.

Difference in euros

Instead of cents only, the app shows how much more or less a full tank costs compared with the nearest station – detour included. You see at once whether the drive pays off.

Favourites, map, navigation

Save favourite stations with a star, see every station on the built-in map and start navigation with one tap.

Made for the car

Large buttons, a dark design and clear contrast – so the app is quick and safe to use on the go.

All features

What the app does in detail.

Spritpreise is much more than a price list. Here is every feature of the current version 12.1 – from the first look at the list to reading the car via OBD-II.

01Home screen & list

Switch between E5, E10 and diesel with one tap – changing the car selects the right fuel automatically
“Nearby” within 1 to 25 km, or only “Favourites”, wherever they are
Sort by distance, price, savings including the detour, or name
Check prices in another town without driving there
Filters for autogas and for your preferred station brands
“Best price” label for the cheapest and “next door” for the nearest station
For every station: how much more or less a full tank costs compared with the nearest one – detour included, marked green, orange or red
Star for favourites, green arrow hands the destination straight to navigation
Lock-out protection: prices are requested at most once a minute, the app shows the seconds left

02Station details

Open or closed and distance – updated live on the move
All three prices, the selected fuel highlighted
Calculation for your car: full tank in euros, round-trip detour in km and euros, total
Personal price history: “3.2 cents cheaper than usual at this station” – after five observations
“How far really?” – calculates the real driving route instead of a straight line
Neighbourhood comparison: “Worth it: save €6.91 at …” or “Filling up here is cheaper”
Opening hours and a direct jump to this station's price history

03Map

Price tags instead of dots: green for the cheapest, dark blue for close, burgundy for expensive
Overlapping tags are hidden automatically – the most expensive first
Blue dot on a tag marks autogas, your position is a glowing circle
Light or dark map, zoom by pinch, double tap or buttons
Works offline too: loaded map tiles are stored and cleaned up automatically above 60 MB

04Route & trip mode

Enter a destination or pick one from history – stations along the way in 3 to 15 seconds
Own filters: maximum detour, sort by route, price or savings, there and back, how far ahead to search
“Let's go”: the list shows only stations on the way – too far off or already passed are hidden
Trip window over other apps: remaining kilometres, time, litres and euros – without new requests
The route stays saved and can be resumed later

05Speed circle & trip window

Floating speed circle over any app, freely movable
One tap turns it into a “pill” with the two nearest stations, price and distance
Double tap opens the app – so you never fall into it by accident
Colour by the car's economical speed: green, orange (up to 15 km/h above), red
Shrinks back after 10 seconds without touch, long press switches it off

06Widgets

Three sizes: compact (best station), medium (several) and large (up to eight stations)
Medium and large scroll, tapping a row opens the station
Own refresh button, choice of nearest or favourites and sorting

07Learning journal

The app remembers every price: average per station, 24 hours of the day, places and trips
Time-of-day hint: “Currently 8.6 cents above usual – cheapest around 11 am”
Place hint: “Usually 4.2 cents cheaper in Troisdorf – 6 km from here”
Silent background sampling every 2 to 12 hours so evening and night prices are captured too
Two ways to find the “expensive hour” – per station or by average, chosen automatically
“What has accumulated” overview and price history from a few hours up to a year

08Autogas (LPG)

Autogas prices are not reported in Germany – so the app remembers where gas is available
Mark it right in the station: available · not available · don't know
After two minutes at the pump the app asks – at most once an hour
Learning mode on the road: a short question when passing by, optionally by voice
Existing marks only change after confirmation – no accidental overwriting

09Reading the car via OBD-II

With an ELM327 Bluetooth adapter: fuel level, consumption, speed, temperature and voltage in 10 to 20 seconds
“What can my car do?” – lists every value the vehicle provides
All values on a separate screen as cards with code, name, value and explanation
Raw adapter log to copy
Short connection instead of a permanent one – other apps such as Car Scanner keep working and the battery is spared
Works with most cars using the OBD-II standard (petrol from 2001, diesel from 2004)

10In the car & automation

Detects getting in via the Bluetooth connection to the car radio
On getting in: tip for the cheapest station – as a notification or by voice
“Ahead only” mode: shows stations in the driving direction and switches on by itself above a set speed
Motorway detection: stations on your side of the road, expensive motorway stations can be hidden
Several cars with consumption, tank size, fuel and their own economical speed

11Voice

Off, male, female or system voice
Speaks like a sat-nav: music dips briefly, navigation prompts stay audible
Speed warning with your own text, thresholds and repetition adjustable

12Usability & design

Light, dark, follow system or automatic by light sensor
Own brightness and automatic dimming in the evening
Languages: German, English, Russian
Guided tour for every screen – repeatable at any time
Almost every button explains itself on long press

13Privacy & control

Journal, marks, addresses and cars stay on the phone only
Price retention from 14 days to unlimited, default 90 days
“Forget in parts”: delete price history, station averages, hours or trips separately
Notification when a favourite station gets cheaper
Every feature can be switched on and off individually – nothing is forced on you

To be honest: what the app can't do

Prices for Germany only – the source is the German market transparency unit for fuels
No gas prices, because they are not reported
No manufacturer-specific vehicle data – only the open OBD-II standard
