Accessible for 10 days, then only with Business Access:At prices well over two euros, refueling is currently one of the nightmares of German drivers.And that's why motorists should also be to blame for the fact that sunflower and rapeseed oil are now becoming scarce.The crude explanations on the Internet: Diesel drivers, angry about the fuel prices, would tip the vegetable oil into their tanks to save.The fact that modern diesel engines with their complex technology for cleaning exhaust gases cannot run on vegetable oil at all - there is a risk of expensive engine damage - does not really bother the posters with these claims.If you really want to save money when filling up, there is only one legal option: consistently drive to the cheapest gas station.With local price differences of mostly a maximum of around 12 cents per liter, this is only worthwhile to a limited extent - for a 66-liter tank, that's 7.92 euros.If a detour has to be taken, the potential savings are quickly wasted.A trip to a neighboring country seems to be more worthwhile – for example in connection with a Sunday trip or a business trip.And even with the upcoming Easter holiday, you can save a lot of money with tactically correct refuelling.At the time of our research, for example, a liter of diesel cost between 2.25 and 2.37 euros in Munich.In neighboring Austria, on the other hand, the fuel was available for 2.02 euros – making a saving of 15.18 euros when you fill up.It is even cheaper if the trip leads to Switzerland.The diesel was available there for CHF 1.70 (EUR 1.64).Compared to Munich, that would be a saving of over 40 euros per tank of fuel – even though Switzerland used to be one of the most expensive diesel countries.Even in France, diesel was significantly cheaper at EUR 1.92 than in Munich.So if you plan your trip to the Easter holiday wisely in terms of tank technology, you will quickly save the equivalent of a dinner for two.But how can the refueling stops be planned tactically from home for the trip?Either the driver has a built-in navigation system that displays the current fuel prices, or he uses one of the numerous tank apps that are available for Android and iOS.The first option is usually reserved for drivers of a premium model.For example, Mercedes had equipped the navigation system of its E-Class with a corresponding fuel price display.However, the Stuttgart-based company is gradually discontinuing the cloud service - in other words, it simply cannot be extended after the free three years have expired.Ultimately, the majority of drivers who are plagued by fuel prices can only use one of the numerous tank apps.If you enter the search term “fuel apps” in the Google Play Store, you will get almost 250 hits.But which app is the right one for my needs?Similar to a requirement specification for a software project, we have created a short list as a specification that contains our personal must-have requirements for a tank app.For us, this includes the following points:By loading the video, you accept YouTube's privacy policy.Learn moreWith these requirements in the background, we took a closer look at three tank apps: The app “Benzinpreis-Blitz” from the German software company MW WebWork, the app “clever-tanken.de”, which is popular with over 270,000 downloads, and the solution from the car manufacturer Mercedes "Bertha.Your gas station app".If the fuel price is also to be checked when traveling abroad, then the fuel price flash is our clear favourite.In addition to Germany, the app shows the prices in six other countries: Austria, Luxembourg, France, Portugal, Spain and Italy.Although the app shows which fuel cards a station supports, it is not possible to search for them.The information about the additional services offered by a gas station is also very detailed.When it comes to in-car payment, the fuel price flash works together with the cooperation partner rydpay.In Munich, the app found 30 acceptance points within a 25-kilometer radius.With a simple touch in the app, navigation to the selected gas station can be started directly via Google Maps.Unfortunately, it is not possible to transmit the search results to the vehicle navigation system.For an annual fee of 1.49 euros, the app can be activated without advertising.Even though clever-tanken.de is one of the most popular Android tank apps, we liked it the least in our comparison.A shortcoming is that it only shows the prices of German gas stations.A use abroad falls flat.We noticed positively that the app not only supports the search for standard fuels, but also allows search criteria such as hydrogen, LNG, AdBlue, bioethanol, etc.On the other hand, it is not possible to search for other criteria, such as accepted fuel cards, etc.In addition, there is only one filter that can be used to set whether closed gas stations, old prices and gas stations without prices are also displayed.A granular adjustment is not possible.For in-car payment, the app supports the in-house “clever-pay”.Unfortunately, there were only two acceptance points in Munich within a 25-kilometer radius of our location.The petrol stations found can be exported directly to Google Maps on the smartphone.The address could also be transmitted to the vehicle navigation system using the "Share" function.If the ads in the app annoy you, you can get an ad-free version for an annual fee of 1.99 euros.The Bertha app is the only application in our test trio that does not have any in-app advertising.In addition to Germany, fuel prices are displayed in four other countries: Austria, Switzerland, the Netherlands and Belgium.In contrast to the other two apps, Bertha only shows the search results directly on the map, there is no list view.Bertha is the only app in our trio that supports the gas station search for accepted fuel cards.However, this positive impression is nullified by the fact that only the search for three types of fuel (Super E5, Super E10 and diesel) is supported.For in-car payment, Mercedes relies on its in-house Bertha Pay, which requires a Visa or Mastercard credit card.Bertha indicated 22 acceptance points for Munich.It was possible to transfer the found gas station address to both Google Maps and the car navigation system.With a view to our personal specifications, none of the three candidates was able to gain a position as a favourite.If the gasoline price flash also displayed the prices for Switzerland and supported the transmission of the results to the navigation system, that would be our winner.In the future, he will have to share space with the Bertha app on his smartphone, although the latter is more likely to be used in Germany, while the petrol price flash is used when traveling abroad.Speaking of foreign countries - it should be noted here that the in-car payment of the apps usually only works in Germany.It should also be noted that there may be temporary restrictions on the apps at the moment due to the price explosion due to the Ukraine war, since the backend systems are sometimes not able to cope with the flood of user requests.*Jürgen Hill is chief reporter Future Technologies at COMPUTERWOCHE.The graduate journalist and computer scientist is currently working on current IT trends such as AI, quantum computing, digital twins, IoT, digitization etc. He also has a long-standing background in the field of communications with all its facets (TK, mobile, LAN, WAN).Thanks to a dedicated user community, the 25-year-old open-source network mapper continues to be the standard for security-focused port scanning.[...]The word "open" in open-core models is misleading: Often the offerings are not open at all and cause problems.Managed platform provider Instaclustr gives four reasons why open source software is a better choice.[...]A high-end cell phone at a mid-range price – doesn't that exist?And if: We took a close look at the Oppo Find X5 with 5G Turbo.[...]Better price conditions, a larger range of products and greater convenience: online marketplaces such as Amazon, eBay or Zalando are becoming increasingly popular with consumers.Above all, the delivery is an important factor that influences the purchase decision.[...]Non-cash benefits on prepaid credit cards, smartphones, daycare and health allowances: companies can reward employees in many ways without increasing their salary.This is beneficial for both.[...]Encouraging the voluntary commitment of their employees pays off for companies in many ways.Voluntary assignments by IT specialists can be particularly beneficial.[...]The Graz software and UX experts now have a branch in Portugal.With the opening of the new location in Porto, international customers should be better looked after and employees from all over the world should be addressed.[...]Most organizations are aware of the need to move from perimeter-based security to a zero-trust model.They also know they can't buy Zero Trust as an off-the-shelf product.Here are eight questions to ask prospective vendors.[...]Security Assertion Markup Language (SAML) is an open standard that defines how providers can offer both authentication and authorization services.Here's everything you need to know about it.[...]Your email address will not be published.Please leave this field blank Sign up for the daily newsletter: Privacy Policy -
