Mobile App Development Services
iOS and Android apps - native or cross-platform - wired into the systems your business already runs.

Webentwicklung
Most business apps fail for a reason that has nothing to do with the app. They are built as an island - their own accounts, their own product list, their own idea of what an order is - and then someone has to keep that island in step with the ERP, the store and the warehouse. Within a year the app is showing yesterday's prices and nobody trusts it.
We build the app and the connection at the same time, because the connection is where the work is. The store accounts and the developer accounts stay in your name.
Native or cross-platform, and how the choice is made
There is no general answer, only a specific one. What decides it is what the app has to reach for, and how much of the screen has to feel like the platform it is running on.
Cross-platform is usually right
One codebase covers both stores, and for the overwhelming majority of business apps nothing is lost:
The app is forms, lists, search and a camera - an order pad, a stock count, a field-service log, a customer portal- You want the same release on both platforms on the same day, with one team
- The screens will change often, and paying for every change twice is what kills the roadmap
Native earns its cost when
The extra build is worth it in a narrower set of cases:
- Continuous hardware access - Bluetooth peripherals, sustained scanning, background location
- Heavy graphics, video processing, or anything with a frame budget
- Deep platform integration: widgets, watch apps, share sheets, system-level shortcuts
We will tell you which one your case is before the estimate, and we will tell you when the honest answer is that you do not need an app at all - a responsive web application installs nothing, updates without review, and is the right answer more often than the industry admits.
The part that is actually hard
An app is a client. Something has to serve it, and that something is your existing systems, which were not designed to be talked to by a phone on a train with two bars of signal.
- An API layer over what you already run - ERP, CRM, the store, the warehouse - rather than a second copy of the data
- Offline behaviour that is decided, not accidental: what can be done with no signal, and what happens to it when the signal returns
- Authentication that matches the accounts your people already have, including single sign-on where you have it
- Push notifications that are worth receiving, which mostly means far fewer of them than the first specification asks for
- Release, signing and store submission for both Apple and Google, under your own developer accounts
What it costs to keep
An app is not finished when it ships. Apple and Google change their requirements on their own schedule, and an app nobody touches for a year is an app that stops being downloadable. Budget for that from the start, or do not build the app.
- Two operating system releases a year, each of which can break something
- Store policy changes, privacy manifests and permission prompts that have to be answered
- Certificate and provisioning renewals that will lock you out if they lapse
Häufig gestellte Fragen
Do we need a mobile app at all?
Often not. If the app would be a browser with your logo on it, a responsive web application does the same job with no store review, no install and no two-platform bill. An app earns its place when it needs the camera, the scanner, offline use, or a place on the home screen that people actually tap every day.
Can it connect to our ERP or store?
That is normally the reason to build it. We put an API layer over what you already run rather than copying your data into the app's own database, so the app shows the same numbers as everything else.
Who owns the App Store and Play accounts?
You do. We publish under your developer accounts, and the source repository is yours from the first commit. If you change agency, nothing has to be re-registered.
Do you do the ongoing maintenance?
Yes, and we will say so in the estimate rather than after it. Two operating system releases a year, store policy changes and certificate renewals are not optional work - an app nobody maintains stops being installable.
Tell us what the app has to reach
The useful first conversation is not about screens. It is about which systems the app has to read from and write to, and what has to work when there is no signal - those two answers decide most of the rest.
