iOS App Development · Frankfurt · Taunus
Native iOS apps, built solo.
I conceive, design and code native iOS apps single-handedly — Swift/SwiftUI, my own backend, shipped through App Store review. No „I deliver the design, others do the coding". Backed by published apps. From Oberursel near Frankfurt, for the Rhine-Main region.
01 — App Development
Native iOS Apps & Web Apps
Concept & UX design
Swift / SwiftUI (native)
Backend myself — Supabase / StoreKit
App Store submission & review
Maintenance & iOS updates
Most „app freelancers" only deliver the design — for the actual programming you then need a second person. I am the exception: I build the app end to end, alone. Swift/SwiftUI for the interface, my own backend (Supabase) and in-app purchases (StoreKit 2) behind it, and I take it through App Store review myself. Backed by my own published apps — not by promises.
PROZESS
How your app comes to life
01
Concept & UX
We clarify what the app needs to do, for whom, and cut an MVP. The user flow is set before a single line of code.
02
Design
UI with a real iOS feel. You see the screens before they are built.
03
Swift + Backend
Native development in Swift/SwiftUI, database & logic (Supabase), in-app purchases via StoreKit — all from one hand.
04
App Store
Submission, review support, launch. Adjustments for new iOS versions included.

02 — Full-Stack
Frontend AND backend
Swift / SwiftUI (native)
Supabase / my own backend
StoreKit 2 — in-app purchases
Push, offline, device sensors
No second developer needed
The difference to many app freelancers: I don’t just build the visible app, but the database behind it too. Frontend, backend and store release come from one hand — you don’t need a second person for the programming.
03 — Agency or freelancer
Why a single person is often the better choice
One fixed contact
No project-manager overhead
Direct, fast coordination
Fair solo rates
You talk to the person who builds
Agencies have teams and redundancy — and the matching overhead. With me you talk directly to the developer, no loop. For focused iOS apps (MVP to mid-range) that is faster and cheaper. For very large projects I am honest: then a team makes more sense.
04 — Maintenance
After launch
iOS update adjustments
Bug fixes & store updates
New features
Backend monitoring
Hourly or retainer
Operating-system updates regularly force apps into code changes. I keep your app running, fix bugs, build new features — and look after the backend behind it. Billed hourly or as a retainer.
MVP-First
Start small, get real feedback, then expand
3–4 core features first
Initial investment kept in check
Real user feedback before expensive extras
Good apps start as an MVP — a basic version with the most important features. That saves budget, gets your app into the store faster, and delivers real user feedback before expensive add-ons are built.
Frequently asked questions
Do you build the backend too, or just the design?
Both. I am full-stack — I build the app interface in Swift AND the database and logic behind it (Supabase, StoreKit). You don’t need a second person for the programming.
What does an iOS app cost?
It strongly depends on scope. A focused iOS app starts in the mid four-figure range; a parallel Android version or a complex backend accordingly more. Plus the one-off Apple Developer account (€99/year). In the first call I estimate effort and tools transparently.
Do you really get apps through App Store review?
Yes — all my apps (Fridoo, Subora, Good Fuel and others) are live on the App Store. Getting an app cleanly through store review is a discipline of its own beside the coding, and I do it regularly.
Native iOS or cross-platform?
It depends on the goal. Native iOS (Swift) for the best performance and feel; cross-platform or a web app if iOS and Android should come from one codebase. I advise honestly what fits your budget.
How long does an app take?
A focused MVP often in a few weeks, larger apps accordingly longer. After the first call I give you a realistic estimate.
Do you also build web apps & dashboards?
Yes — React/Next with my own backend (Supabase): customer portals, internal tools, dashboards. When a website isn’t enough but a native app isn’t needed, that is often the right path.
