Learn to perform mental arithmetic with confidence
By purchasing our mental arithmetic product, you are investing in your future. We have developed the product to create the best possible environment for our customers to train mental arithmetic sustainably and gain self-confidence through dynamically generated tasks (no memory effect).
You receive two modules with your purchase:
- eBook with important tips and tricks for quick mental arithmetic and typical number ranges for memorization
- Computer-Based Training (CBT) for interactive learning
This product is the perfect complement to Math Word Problems – Mathematical Problems. The currently open product deals with mental arithmetic.
Configuration options for the CBT
- Detailed statistics on your learning progress
- Mapping of all basic arithmetic operations (addition, subtraction, multiplication / division) as well as special tasks for individual airlines
- Difficulty levels of the dynamically generated tasks
- Choice of input: input field for keyboard or result selection for mobile touch devices (with different levels of difficulty)
- An optional countdown can be switched on to create the feeling of an exam mode
- An optional signal tone (when the countdown is switched on) 5 seconds before expiry simulates the special characteristics for KRN in the DLR test
Alternative to Mathemakustik
With the Easyflight Training App, we offer an attractive alternative to Mathemakustik in combination with this product. Our CBT for this product enables you to perform mental arithmetic tasks both visually and acoustically. We simulate your mental arithmetic test on site in the app (for some assessments such as the DLR certificate for the Lufthansa Group, for example). The audio output can either be switched on for visual presentation of the task or switched on exclusively. You can also choose from various languages (including English, German, French and Spanish). And all at an attractive price!

Patrick (verified owner) –
Very good, I think its best option to train Mental Arithmetic for the DLR Test
Constantin (verified owner) –
Excelent to practice KRN, but a would love an option with an timer like in the DLR 🙂
Nils (verified owner) –
It has many different excercises.
Kelim (verified owner) –
lots of settings, sometimes doesn’t work for example the audio, but after a page reload it’s fine again
Easyflight Training –
Hi Kelim, thanks for your feedback. If you encounter any problems, feel free to also directly get in touch with us. There are some audio limitations on Apple devices in certain cases. We recommend that you try another browser such as Google Chrome or Microsoft Edge and give it another try. Thanks for your review and we wish you much learning success! ⭐
Luis (verified owner) –

Tim Leutwyler (verified owner) –

Leonard (verified owner) –
Tests are good. TVT sometimes buggy
Easyflight Training –
Hi Leonard, thanks for your feedback and we’re happy to see you as a happy customer! Please let us know where you find potentials bugs. We are excited to fix them!
Jens (verified owner) –
The mental arithmetic module in the Easyflight App is very well designed and provides an excellent training environment. One of its biggest strengths is the flexibility in adjusting the difficulty level—you can not only adapt the exercises to your current skill level, but also challenge yourself with problems that are far more complex than what’s actually required for the real test. This is a huge advantage for preparation, as it helps build speed, accuracy, and confidence beyond the minimum standard. Whether you want to solidify basic operations or push your limits with more advanced calculations, the module allows for highly targeted practice. In short: a very effective and well-thought-out tool for improving mental math skills—highly recommended.

Really nice app, offers a ton of personalisation for the desired difficulty.
The ebook is nice, just wish it would cover in more detail, mental calculations methods.

the Voice is gone sometimes
Easyflight Training –
Hi Wijona, thanks for your feedback! We’re not aware of that bug. However, we know that there are a few performance differences between devices and operating systems which we can’t influence. Therefore, maybe you can try another device, such as another smartphone or another computer? Please let us know how it goes and get in touch with us if the issue persists.

It´s the only training program that I can certainly trust that it will prepare me for the DLR-Test properly.
Lasse (verified owner) –
Das beste im verglich zu anderen Apps ist das man es überall nutzen kann. Ob in der Bahn, Zuhause oder in der Uni. Außerdem ist die App intuitiv und man sieht wie man sich verbessert.
Dennis Fabian (verified owner) –
Good KRN Training APP. Perfect for DLR Prep.
maelbadts (verified owner) –
So good, like all the other test we have access to an useful guide with calculation methode.
I recommande
alexia (verified owner) –
Kopfrechnen war einer der Tests, bei dem ich quasi von 0 anfangen musste zu üben. Besonders geholfen haben mir die Ebooks mit zahlreichen Tipps und Tricks zum Kopfrechen. Zu Beginn fand ich es außerdem hilfreich, die Rechnungen sich visuell und gleichzeitig akustisch anzeigen zu lassen. Bei schwierigeren Aufgaben, hat außerdem die Möglichkeit geholfen, sich mögliche Lösungen anzeigen zu lassen.
Julian (verified owner) –
Really good but a little too hard compared to the real test
pheinrich210 (verified owner) –
Great software! I love the mobile app
Ray (verified owner) –
Very Nice preparation tool, well worth it!
yanick (verified owner) –
Top Product! Easy to use
Christopher (verified owner) –
By choosing the settings you can directly work on your weaknesses and thus improve your mental arithmetic. The guide providing tips and tricks is also very helpful.
Marvin (verified owner) –
Gute Vorbereitung für den DLR, insbesondere die Tatsache, dass man eine reine Audioausgabe einstellen kann. Auch die Rechen Tipps & Tricks aus dem inkludierten Guide erscheinen mir hilfreich. Für die weitere Entwicklung würde ich mir unterschiedliche Zeitlimits je nach Schwierigkeitsgrad der Aufgabe und dass man den 5 Sekunden Warnton unabhängig von der Aktivierung des Countdowns einstellen kann wünschen.
Marius0202 (verified owner) –
overall very good experience, very close to the DLR which I am preparing for
Roberta (verified owner) –
It is challenging, but it can really help you prepare for KRN. Great the possibility to change the difficulty level and set the timer. It would be useful to include the option to hide the problem, because in DLR the numbers are not presented, but only pronounced.
Easyflight Training – Administrator –
Hi Roberta, thank a lot for your positive feedback! Our app allows you to visually hide the task and to just audio-output the task. Feel free to reach out to us if you need further assistance. Enjoy your learning experience!
Moricce (verified owner) –
eine weiter gute Möglichkeit sich für den DLR Test vorzubereiten!
Phil 10 (verified owner) –
The amount of variety within the tasks.
elias (verified owner) –
maybe no visual timer, but a signal tone. And also varying times for more or less difficult tasks.
Easyflight Training – Administrator –
Hi Elias, thanks for your feedback. Our development for the signal tone has almost finished. We plan to release an update within the next 3-4 days.
Patrick (verified owner) –
thankyou so much for this app. 100% happy with it
