Build software that works in daily use.
Steingraf Labs develops websites, web apps, iOS and Android products, customer portals and internal software—including invoicing, accounting and administration workflows.
The result can be a fast website, an app, a customer portal or an internal tool. What matters is what people need to get done.
Discuss a project
The task first. Then the system.
We clarify users, data and workflows before fixing the interface and technology.
Apps & web apps
Mobile and browser-based products are built around the decisive user workflow.
- iOS, Android and web
- Backend and integrations
- Quality, privacy and release
Internal software
Dedicated tools replace spreadsheets, broken hand-offs and manual routine where standard software does not fit.
- Invoicing and administration
- Dashboards and approvals
- Automation and reporting

Product planning
App brief and MVP: resolve the risk before building
A dependable app brief is not a collection of as many features as possible. It states who solves which problem in what journey and how the team will know that the first release works.
Read guide Technical decisioniOS, Android or web app: decide from the moment of use
The right platform is not the one with the newest label. It is the one that carries the most important journey reliably on the audience's devices and can be operated sensibly afterwards.
Read guide Backend and operationsMobile app backend: invisible to users, obvious when it fails
Sign-in, data, synchronization, uploads, notifications and administration do not live in a polished app screen. They need a backend that contains failures, enforces permissions and can be operated after release.

Questions
Before the first build
What can Steingraf Labs develop?+
Websites, shops, web apps, iOS and Android apps, customer portals, internal tools and custom business software. The exact scope is agreed before the proposal.
Native or cross-platform?+
It depends on experience, device capabilities, team and long-term operation. The decision is made in the product sprint, not by fashion.
Is support available after launch?+
Yes. Maintenance, updates, release support, product analytics and ASO can be agreed as a clear ongoing scope.
Next step
The idea does not fit a category? Good.
Website, app, platform, internal tool, shop, invoicing software or film: show us the problem and the idea. We turn it into a rigorous first build and tell you plainly what the next step requires.
