App Agency
A good app just feels natural to use. We build mobile applications your users actually enjoy – with the right backend included.
Then a conversation is the fastest route to an assessment.
Native apps that fit right into the Apple ecosystem and feel genuinely fast.
One codebase for iOS and Android when you want to serve both platforms efficiently.
The invisible backbone: user management, data sync and push notifications – built on Laravel.
Updates for new operating system versions, new features and ongoing support.
Native development – with SwiftUI for iOS, for example – gives you the best performance and full access to every device feature. Cross-platform approaches share one codebase for iOS and Android, which saves time and budget.
We help you weigh both honestly against what you are building – and we plan the backend from day one, so app and server work together smoothly.
The decision depends less on the technology than on what you are building. If the app needs deep access to the camera, Bluetooth, background location or unusual gestures, native is the more honest choice. If it is essentially an interface to data from your system – jobs, stock, forms – cross-platform saves noticeable budget without users spotting a difference. We tell you upfront which category your case falls into.
Something many people underestimate: the App Store is not hosting, it is a review process. Apple rejects submissions regularly, and rarely for technical reasons – usually for missing privacy declarations, unclear account deletion, forced login without justification, or screenshots that do not match the app. We handle the submission including those formalities and know where it tends to snag. That we have our own app in the store, the WebDAV Browser, is not a marketing detail here – it is why we know the process.
An app is also never finished. iOS and Android ship a new major version every year, and anything that does not keep up eventually breaks on new devices or falls out of the store. So plan the app as a running system with an annual maintenance budget, not as a one-off project. That is the line item missing from quotes most often.
The app on the device talks to the backend, database and push services through an API.
Honestly
Not every enquiry belongs with us. These are the ones we turn down in the intro call – here they are upfront, so you can skip the call.
Then a website or web app is the cheaper route – no store review, no yearly maintenance obligation.
Better fit: Web DevelopmentiOS and Android ship a new major version every year. Fall behind and you eventually drop out of the store.
Apple's review rejects that regularly – guideline 4.2 requires functionality of its own.
Pick the shape that matches your situation – the price is right there, so you never have to ask for it. It is a ballpark figure; your binding quote comes after a short conversation. If you would rather work it out yourself, use the package configurator: put together what you need there and see your price range right away.

What the price depends on
We bill custom projects transparently by the hour. After a free intro call you get an honest estimate from us here in Bavaria – so you know where you stand before anything starts.
Situation, solution, result – that is how we work. The projects are described anonymously for confidentiality.
Who builds this?
At Viovenia your project is not passed between rotating teams – it is built directly by Marcel, senior software engineer. You talk to the person who writes your code, from the first call to running in production. No project-manager loop, no ticket ping-pong.
Transparent and free of stress – that is how working with us goes. More about our process.
Half an hour where you describe the project and get concrete questions back. It ends with a first read on feasibility and rough size – including when that read is “not worth it”.
In writing, with scope, the technology involved, the assumptions behind it and what is explicitly not included. Split into “needed at launch” and “can come later”, so the scope stays negotiable.
After each stage there is something usable on a test environment, not just a status report. Change requests go in where they are cheapest: before the next stage starts.
Before going live: a run through the core workflows, a backup concept, monitoring switched on. Afterwards you get access, source code and documentation handed over in full, not on request.
Updates, monitoring and further development – as fixed care or on call. No minimum term: what keeps you should be the work, not the contract.
A web app runs in the browser — no store, one codebase, cheaper for most business apps. When it pays off, where it hits limits, and what it costs.
