00 / Software · Rail operations
We build software for rail operators (Eisenbahnverkehrsunternehmen, EVU) where your dispatch system stops: apps for the cab, forms instead of paper, APIs between your systems. Our app Bremshelfer calculates brake percentage (Bremshundertstel) for train drivers under Ril 915, even without a signal.

01 / Already built
Bremshelfer is our own product, not a client job. The app calculates a train’s brake percentage under Ril 915 and shows every deduction below the result. We built it together with a train driver.

Bremshelfer · Specialist app / offline-first
App for train drivers to calculate brake percentage under Ril 915, with a formula reference and multiple traction, fully usable offline.
Free on the Play Store. A train driver checked the results against his own calculations during development.
Result Built in one month. The same calculation is on our website as a calculator in the browser.
Below the result it says which deduction applied for the train length, which brake position and which warning. Anyone who wants to check the math can.
Calculator in the browser ↗Each locomotive gets its own deduction, and the app recommends the brake position. Six classes from BR 182 to BR 193 are preloaded, you can add more yourself.
Calculation, locomotive classes, history and formula reference are stored on the phone. The screenshots on our product page were taken in airplane mode.
Train drivers send us their feedback directly from the app. Nobody has to look up an address to report something.

An app in the cab works under different conditions than a program in the office. We built these four into Bremshelfer, and they apply to everything we build for rail operators.
In tunnels, in cuttings, in the countryside. So whatever the driver needs on the way is stored on the device. Bremshelfer even collects its usage statistics there and only sends them once there’s a signal again.
What applies is set out in Ril 915 and in your company’s own rules. So our software shows which rule it calculates by, and it takes your rules. In Bremshelfer you enter your own deductions by hand.
Calculations happen at four in the morning too, when there’s nobody around to ask. The interface has to explain itself: enter the train, choose the class, calculate.
Earlier calculations stay in the history on the device, with result and locomotive class. If someone asks later what you calculated with, you look it up there.
03 / For rail operators
This is what we offer, not a list of references. Apart from Bremshelfer, we haven’t built anything for rail operations yet. Projects from other industries show how we build the individual parts.
An app that calculates or checks a rule from your rulebook, on the device and without a signal. With the working shown below the result, like in Bremshelfer.
Reports, checklists, handovers: filled in on the phone, even in a dead zone, and sent as soon as there’s a signal again. They arrive in the office complete and legible.
Data moves from one system to the next without anyone typing it in again. At Turkish Home, the prices in the shop come from the retailer’s POS system every morning.
View Turkish Home ↗The list on the shared drive becomes a system in the browser, with roles, login and audit log. That’s how Zularis is built, our CRM for vehicle registration services. It has been running at a registration service in Duisburg since May 2026.

For dispatching, rostering and train preparation there are ready-made systems, such as zedas®cargo or dispoboxx. We don’t rebuild those.
We build what’s missing next to them. If it can be bought off the shelf, we tell you in the intro call.
05 / Live
Your drivers work nights too, and then the app has to manage without us. For everything else, the contract says when we can be reached, how fast we respond and where your data is stored.
06 / What it costs
We bill by the hour, there’s no minimum. Bremshelfer was finished after one month. The project assistant gives you a rough range for your project in four questions, without you leaving any contact details.
Every payment comes after a sign-off. You can step out between any two milestones.
Cost estimate in four questions ↗07 / How it works
Before we build, we spend two days at your operation and watch how the work gets done. That’s where the specification and the quote come from. Then we build in one-week sprints, and at the end of each week you see a demo.

09 / More
The intro call costs nothing, and neither does the cost estimate after it. If what you need can be bought off the shelf, we tell you its name and send no invoice.
