The off-the-shelf app
Standard apps don’t know your processes. In the end your operation adapts to the app, not the other way around. Your edge is lost.
Business Apps with .NET MAUI
“I need an app.”
Your field staff work on paper, your drivers call in by phone, and in the evening someone types it all into the system. We build business apps with .NET MAUI: one codebase for Android, iOS, Windows and macOS, offline-capable and deeply integrated into your existing .NET software.
Does this sound familiar?
Your software is good. But it stays at the desk.
In the office everything runs digitally. But exactly where your people are out and about, the chain breaks:
- Field staff, drivers or fitters capture data on paper or by shouting it across
- Data is typed up in the evening, with errors and a day’s delay
- In the warehouse, on the construction site or in a dead zone, offline capability is needed
- Barcode and scanner processes run right past the software
- Your existing app is technically outdated, store warnings included
- Good people expect modern tools, even out in the field

Three paths that fail
What does NOT help now.
The cheap agency
Sounds cheap, turns out expensive: language barriers, quality problems, and after go-live no one is reachable anymore who could maintain the app.
Building natively twice
One app for iOS, one for Android: double the code, double the maintenance, double the cost. And your .NET know-how is of no use to you in Swift and Kotlin.
The better way
One codebase. All platforms. Your .NET.
With .NET MAUI your app is built in the technology your software already runs on. André Krämer is a .NET MAUI book author, contributor and 13-time Microsoft MVP. This knowledge goes into every app we build.
One codebase
Android, iOS, Windows and macOS from a single project. New features appear everywhere at the same time, maintenance happens only once.
Deeply integrated
The app talks directly to your .NET backend and your industry solution. No isolated island, no duplicate data entry.
Offline-first
Warehouse, construction site, dead zone: the app keeps working without a network and synchronizes as soon as there is a connection again. Proven with over 1,000 drivers daily.
Industry-ready
Zebra scanners, barcodes, glove operation: we build apps for the everyday work in production and logistics, not just for the smartphone.
Your app journey, step by step
Every step bookable on its own. Every one is credited.
With the Compass you clarify where the journey is heading. The roadmap shows the way, including a click dummy as a preview. You travel in stages, with an exit at each one. And so your app never breaks down: inspection, release autopilot and maintenance contract. All prices net plus VAT.
Orientation
The App Compass
Your strategy session for getting started: a questionnaire up front, then 90 minutes with André Krämer or a senior architect. Is an app worth it? .NET MAUI, native, or is a web app enough? How much offline do you really need? With an honest recommendation, even if it is “a PWA is enough”.

Assessing the existing app
The App Inspection
You already have an app and wonder how future-proof it is? We review architecture, code quality, update backlog and store compliance. You receive a traffic-light report with a prioritized list of measures and a debrief.
2,499.00 €Fixed price
1,000.00 € credited toward Stage 1
Quick Win
The Release Autopilot
App delivery at the push of a button: we set up automatic builds and store deployments for iOS and Android (Azure DevOps or GitHub Actions), hand everything over to your team and you keep the complete pipeline. Never again release handiwork.
2,499.00 €Fixed price
Strategy
The App Roadmap
A one-day workshop: use cases for field service, drivers or technicians, offline strategy, architecture and store strategy. Afterwards we create a click dummy as a tangible preview of your app and a roadmap with stages and an effort estimate. To wrap up, there is a debrief.

Delivery
Delivery in stages
Stage 1 is your MVP with the most important workflow. Each stage ends with a testable app version (TestFlight or Internal Track) that your people can try out right away. After every stage you decide anew: exit possible at any time, with no loose ends.
- .NET MAUI for Android, iOS, Windows, macOS
- Offline synchronization and barcode/Zebra integration
- Connection to your existing .NET backend

The Compass is fully credited toward the Roadmap, the Roadmap at 25 % toward your first stage. If you come with an existing app, the inspection brings a further 1,000.00 € credit toward Stage 1.
Which means: whoever goes further gets the App Compass effectively for free and bears no risk, because at the start there is the results guarantee.
Proof, not promises
Over 1,000 drivers work with our app every day.
ODYSYS D3 driver app – heavy-load rental
- Crane and aerial-platform drivers receive orders, documents and feedback directly on the device.
- 100 % offline-capable: the app works even where there is no network, and synchronizes later.
- Continuously developed further since release, as a fixed part of the D3 industry solution.
“The driver app is now a strong argument for us in sales. It closes the gap between dispatch and driver and makes D3 even more valuable for our customers in daily use.”
The beginning of a bigger journey
Many of our modernization customers started with an app.
At Odysys the driver app was the first step. Today we are modernizing the complete industry solution there according to our Legacy-to-Innovation program. An app is often the fastest way to deliver new value to your customers while the big modernization runs stage by stage.

Maybe you don’t need an app at all.
Sometimes a well-made web application that runs in the browser on a tablet is enough. No stores, no certificates, lower costs. Whether that is the case for you is what the App Compass clarifies, and if the answer is “no app”, we will tell you so. That is what the results guarantee stands for.
Request the App Compass · 749.00 €Frequently asked questions
Answered clearly.
What does it cost to have a business app developed?
Seriously, that can only be said after the roadmap, because the scope makes the price. The entry points are fixed prices: App Compass 749.00 €, App Inspection 2,499.00 €, Release Autopilot 2,499.00 €, App Roadmap 4,999.00 € including the click dummy (all net plus VAT, credited toward each other). After that you know your effort estimate per stage, and Stage 1 is your MVP.
.NET MAUI or native development?
For business apps, .NET MAUI is almost always the more economical choice: one codebase for all platforms, direct connection to your .NET systems, and your team can contribute. Two separate native apps only pay off in special cases, for example with extremely platform-specific requirements. The App Compass gives you an honest recommendation on this.
Our app is still based on Xamarin. What now?
Xamarin support ended in May 2024, and the platform no longer meets new store requirements. The path leads to .NET MAUI, and it is well doable: the App Inspection shows what lies ahead of you, then migration happens in stages.
Does the app also work without internet?
Yes, that is standard with us and not an add-on option. The app stores locally and synchronizes automatically as soon as there is a network again. The ODYSYS driver app has run this way for years with over 1,000 drivers, including in halls and dead zones.
Who keeps the app running after go-live?
You have the choice: your team takes over and we accompany them in sparring, or you book the App Maintenance Contract from 498.00 €/month. It covers the yearly mandatory OS and MAUI updates, store compliance, certificates and a support allowance. Your app stays store-ready, without you having to think about it.
Can you connect the app to our existing software?
Yes, that is our core business. We come from the .NET world and connect your app directly to your industry solution or your backend. If needed, we build the necessary interfaces right along with it.
The first step
Ready for 30 minutes that create clarity?
30 minutes, free, no obligation. You talk to someone who understands apps and your .NET world. In the end you will know whether we are the right ones for your project. If you don’t need an app at all, we will tell you openly.
