For businesses
Start a projectSoftware made to measure
Is one of your workflows running on paper, Excel or five different programs today? we build the software that fits it. Afterwards it belongs to you.
From Dornstadt near Ulm: app development for the region →iPhone & iPad apps

- For internal teams or customers
- Push notifications
- Publishing on the App Store
Desktop software

Real software
Not clicked together. Built properly.
An app from an AI builder looks finished in five minutes. Until real customer data goes in, several people work at once and the first update comes along. We build software that keeps running exactly then.
Quickly generated
- Looks finished, the foundation is often missing
- Data in a structure nobody planned
- Security only as good as luck
- Nobody looks after it after launch
Kursun Studio
- Planned architecture and a well-designed database
- Login, permissions and attack protection from day one
- Tested before it goes live
- Updates and maintenance as agreed
Real databaseYour data is cleanly structured, quick to search and ready for years, not for a demo.
SecurityEncrypted connections, protected logins, roles and permissions, protection against abuse.
Data protectionOnly the data that is really needed, with GDPR in mind from the first sketch.
BackupsSo that a mistake or a lost phone doesn't turn into lost data.
Updates & maintenanceNew features, bug fixes and care, so the software still runs years from now.
Clean codeClearly structured and documented. The software belongs to you, no subscription trap.
- 01First callFree. You tell us what bothers you and what the software should do.
- 02PrototypeA clickable draft before a single line of code is written.
- 03DevelopmentRegular builds you can try right away.
- 04Handover & careSetup, training and updates as agreed.

Who we are
Two brackets, one code.
Kursun Studio is run by the two of us as a couple: two developers who came to software in different ways, with years of experience in app and software development.
The tinkerer
Has been programming since childhood, first out of curiosity, then out of passion. Over the years that turned into apps, web applications and desktop programs.
The business informatics graduate
Studied business informatics and has worked in app and software development for years. She understands business processes as well as the code behind them and takes care of clean architecture.
Together we complement each other: ideas and experimentation on one side, method and thoroughness on the other.
FAQ
Good to know
How much does a custom app or software cost?
It depends on the scope: a small web app is different from software with many workflows. After the free first call you get a concrete quote from us before anything is charged.
How long does development take?
Simple web apps are often done within a few weeks; larger projects take longer. You get a clickable prototype early on and regular builds to try afterwards.
Which devices do you build for?
Web apps that run in the browser and on phones and can be installed like an app, apps for iPhone and iPad, and installable programs for Windows and Mac, published on the Microsoft Store if you like.
Do I own the software afterwards?
Yes. Software we build for your business belongs to you afterwards. We only show client projects anonymously and never name names, data or access details.
Do you only work locally?
No. We work with clients all over Germany and beyond. First calls and coordination happen by video or phone; meeting in person is possible by arrangement.
Are these AI-generated apps?
No. We use modern tools where they help, but we plan architecture, database and security ourselves, and every line of code is reviewed, tested and owned by us. The result is software that can be maintained and extended.
Do you look after the software after launch?
Yes, as agreed: we take care of updates, bug fixes and extensions so the software keeps running reliably for years.
About the studio
Two people, one standard.
Kursun Studio is our shared software studio. Every app starts with a real everyday problem and gets polished until it feels obvious.
Client work stays confidential: we never show our clients' names, data or access details in public.
