App Development in Nuremberg
Native Android apps that feel fast, work offline and hold up in the Play Store. From the first sketch to publication, all from one source.
- Android · Kotlin
- Apps on Google Play
- Backend included
// Services
Apps I build
Whether a tool for your team or an app for your customers: I build the app, the backend behind it and take care of publication.
02
Apps for your customers
Customer apps with login, push notifications, bookings or tickets, connected to your existing systems.
03
Backend & interfaces
Every app needs a server: database, API, authentication and an admin interface are developed alongside the app.
04
Publication & maintenance
Play Store listing, privacy policy, data safety form, updates for new Android versions: the app keeps running.
// Process
From idea to Play Store
- 01
Initial consultation
What should the app do, who uses it, which systems already exist? About 30 minutes, free of charge.
- 02
Concept & prototype
A clickable draft of the key screens before a single line of code is written. You then receive a fixed-price quote.
- 03
Development
Native implementation in Kotlin in short stages. You test interim versions directly on your own device.
- 04
Testing & publication
Tests on various devices and Android versions, Play Store approval, privacy policy and legal notice inside the app.
- 05
Further development
New features, adaptation to new Android versions, usage analysis.
// Technology
Native instead of compromise
I build natively with Kotlin rather than with cross-platform frameworks. That means better performance, full access to device features such as Bluetooth, camera or background services, and fewer surprises with Android updates. The backend is built with Next.js and PostgreSQL, so app and server come from one source.

- Android SDK
- Bluetooth & camera
- Push (FCM)
- Local database
- REST APIs
- Next.js backend

Do you also develop iOS apps?
My focus is Android. If your audience mostly uses iPhones, we discuss in the initial consultation whether a web app covers both platforms or whether a partner for iOS makes sense. I do not promise anything I cannot deliver well myself.
How much does an app cost?
The effort depends on the feature set and the backend. After concept and prototype you receive a fixed-price quote. Small internal apps are considerably cheaper than customer apps with login, payments and push notifications.
How long until the app is in the Play Store?
For a focused app, expect two to four months including testing and Google’s approval. Larger apps with a backend take correspondingly longer.
Do I need my own backend?
As soon as data is to be shared between users or managed centrally, yes. I build backend and admin interface alongside the app so everything fits together and you have one point of contact.
Who owns the code?
You do. You receive the complete source code as well as the credentials for the Play Store account and the server.
Do you handle privacy and Play Store policies?
Yes. Privacy policy, permissions, data safety form and Google’s guidelines are a fixed part of every publication.
