The Reality

Most app ideas do not fail
at development, but at marketing.

Many developers can code, but they do not know how to market a product. How to position it in a niche, gain visibility and reach the right people, whether through App Store optimization, social media, SEO or targeted Google Ads campaigns. An app nobody finds is an app nobody uses. YG MEDIA thinks in both dimensions from day one: development and marketing.

Services

From sketch
to launch.

Technically strong. Visually convincing. Strategically thought through and marketing-oriented. This is how apps are built that users keep.

📱

iOS app development

Native iOS apps with SwiftUI. Fast, smooth and with the typical Apple quality users expect. From simple business apps to complex data-driven products with backend integration.

Web apps & PWAs

Web-based applications that run on every device without App Store dependency. Progressive web apps that feel like native apps but work in the browser. Ideal for B2B tools and internal systems.

AI integration in apps

I build real AI features into your app. Intelligent recommendations, natural language processing, personalized user experiences. Not AI as a buzzword, but as a feature that creates real value.

Backend & database

Every app needs a solid, scalable foundation. Built on Supabase and Firebase with authentication, real-time data and secure storage. GDPR compliant, reliable and built to last.

UI/UX Design

Design and development from one source. Every app is first designed and prototyped in Figma, iterated until the result is right, and then developed. No translating between designer and developer.

App Store launch & marketing

App Store optimization (ASO), screenshots, app preview video and the entire submission process. Plus marketing strategies via App Store ads, social media and SEO, so your app actually gets found.

Why YG MEDIA

Not just development.
Marketing too.

YG MEDIA is not a classic development agency. Apps are not just built, but also marketed and placed where the target audience searches and spends time. Whether App Store optimization, social media, SEO or Google Ads: visibility is as much part of the job as clean code.

As an all-rounder, every project is approached from multiple perspectives: technology, design, user behavior and business model. If you have your app built here, you get a product that does not just work, it grows.


Discuss your idea
01

Product thinking instead of order thinking

The end user is always at the center. Own experience in app development shows how intuitive apps have to be for users to use, buy and recommend them.

02

Design, code and marketing from one source

One contact for everything. No translating between designer, developer and marketing agency. From the first sketch to the launch campaign, everything runs from a single source.

03

Scalable architecture from day one

Databases and backend architecture are built to last. What has 100 users today should run just as stable with 100,000, without a complete rebuild.

04

Still on board after launch

App development does not end at go-live. Updates, new features, technical evolution and marketing adjustments are part of the ongoing collaboration.

What you get.

Every app built at YG MEDIA meets these standards. No shortcuts, no technical debt that gets expensive later.

01

Native performance

No hybrid compromises. iOS apps run on native Swift and SwiftUI, smooth and fast the way Apple expects.

02

Clean code

Well-structured, documented code that you or another developer can easily continue working on later.

03

App Store ready

All Apple guidelines followed. App Store screenshots, preview and description, including submission.

04

Privacy & security

GDPR-compliant data storage, secure authentication and transparent privacy for your users.

The Process

From idea to finished app.

Transparent, structured and with clear milestones. You always know where your project stands.

Discuss your idea
01

Discovery & concept

Idea, target audience, key features and business model are analyzed together. The result is a clear concept and a realistic roadmap with defined milestones.

02

Design & prototype

The complete UI/UX design is created in Figma including an interactive prototype. The app becomes visible and testable before a single line of code is written. Feedback rounds until the design is right.

03

Development & testing

The app is developed in sprints with regular updates and test builds on real devices. No surprise moment at the end, but continuous transparency about progress.

04

Launch, marketing & growth

App Store submission, ASO and launch strategy. Plus marketing measures for visibility with your target audience. After go-live, YG MEDIA remains your contact for updates, new features and growth strategy.

FAQ

Frequently asked questions.

Everything you should know about app development.

App development depends heavily on scope and complexity. A simple business app starts at 5,000 euros. Apps with a backend, AI integration and complex design can cost 15,000 euros and more. In the intro call you get a concrete estimate.
A simple app is finished in 6 to 10 weeks. More complex projects take 3 to 6 months. We define the scope together and I stick to the agreed timeline.
The focus is on iOS (SwiftUI) and web apps. If Android is required, that can be implemented as well. Another option are Progressive Web Apps (PWAs) that work equally on Android and iOS and need no separate App Store process.
You need an Apple Developer account (99 euros per year). I take care of the rest: submission, screenshots, App Store description and the communication with Apple in case of questions.
Yes, with full payment the complete source code belongs to you. You get access to the Git repository and can continue development yourself or with another developer.
