App development for your business

I design, build and publish iPhone and Android apps for companies and founders across Germany, working remotely. You deal with one engineer from the first idea to the App Store listing, so nothing gets lost on the way.

What you get

An app that does one job well and is built to be maintained. Depending on your goals, that means:

  • A native iOS app in Swift, or a cross-platform app for iPhone and Android
  • Screen and flow design, so the app is easy to use from the first launch
  • Backend, accounts and payments where your app needs them
  • Publishing to the App Store and Google Play
  • Analytics and crash monitoring, so you see how the app is used and where it fails
  • Updates and support after launch

Why an engineer who ships his own apps

Mobile is where I started, more than ten years ago. I have built apps and SDKs that run inside apps with millions of users, at companies like Pubnative and TVSMILES, and I launched my own apps with more than 500,000 downloads.

I also build and publish iOS apps under my own name, for example Pawwall. That means I know the App Store from the inside: submission, review, paywalls and the updates that follow.

How an app project runs

Four steps, no jargon, and you always know what comes next.

  1. Free call

    30 minutes about your idea, your users and what the app has to achieve.

  2. Plan and fixed quote

    A short written plan with scope, timeline and a fixed price, before any work starts.

  3. Build

    You see working builds every week and give feedback before anything is final.

  4. Launch and support

    I publish the app, show you how it works and stay around for updates.

What affects cost and time

Every app is different, so I do not quote from a price list. These are the things that move the budget and the schedule:

  • The number of screens and features, and how complex each one is
  • Whether you need iPhone only or iPhone and Android
  • Accounts, a backend, payments or connections to other systems
  • How much design work is needed, or whether designs already exist
  • Store requirements and review times, which I cannot control
  • How quickly feedback and content come from your side

After the free call you get a fixed quote, so you know the cost before we start.

Frequently asked questions

Do you build for both iPhone and Android?

Yes. I build native iOS apps in Swift and cross-platform apps for both stores. In the first call we decide which fits your goals, your users and your budget.

Can you also publish the app in the stores?

Yes. I handle the developer account setup together with you, the store listing, the submission and the review process, and I stay on for the first updates.

Does my app need a backend?

Some apps work fully on the device. Others need accounts, syncing or payments, and then a backend is part of the plan. We clarify this in the free call and put it in the quote.

I am not in the same city. Is that a problem?

No. I work remotely for clients across Germany. We talk by call or video, and you see progress every week.

What happens after the launch?

I monitor crashes, look at usage and ship updates. If you want ongoing maintenance, we agree it up front.
