A SwiftUI agency for native Apple apps.
As a SwiftUI agency we build native apps for iPhone, iPad, Mac and Apple Watch from one Swift codebase and take over existing Swift projects. If you also need Android, we say so in the first call.
Our own SwiftUI apps
Chess Clock is on the App Store, Byoyomi Timer is our second SwiftUI app. We built both ourselves.
One Swift codebase
iPhone, iPad, Mac, Apple Watch and Vision Pro from one project, adapted per device.
App Store guidance
Submission, TestFlight and staged rollout are part of the project until Apple approves.

Two players, one iPhone
Split screen with a mirrored opponent side, large digits and one-tap pause. Native SwiftUI, works offline, live on the App Store.
Why we build native apps with SwiftUI.
-
One Swift codebase for every Apple device
iPhone, iPad, Mac, Apple Watch and Vision Pro share logic and most of the interface in one project, with no separate team per device.
More on this
SwiftUI is Apple's declarative UI framework, launched in 2019 and compiled directly for Apple platforms. The basics are on our page What is SwiftUI?
-
Deep integration with the operating system
Widgets, Live Activities, App Clips, Apple Pay, HealthKit and CloudKit go as deep as only native code allows. New iOS APIs usually reach SwiftUI on release day.
-
No Android with SwiftUI
SwiftUI runs on Apple devices only. For iOS and Android from one codebase we recommend Flutter or React Native, before the project starts.
-
AI speeds us up, experience decides
As an AI-first iOS app development agency we build every SwiftUI app AI-assisted because it is faster. Architecture, store compliance and maintainability come from running our own apps.
More on this
You can build a prototype with AI yourself today. Whether an app passes Apple's review and stays maintainable after the next iOS release depends on details: Human Interface Guidelines, battery behaviour, StoreKit edge cases, App Store rejection reasons. We build documented, ready for handover.
Our services as a SwiftUI agency.
SwiftUI App Development
Design, Swift development, device testing and App Store launch for new Apple apps.
DetailsSwiftUI App Developers
Swift developers for your team: project phases, specialist topics, capacity gaps.
DetailsSwiftUI Chat App
Live chat and complete messengers for Apple devices: messaging, push, media, moderation.
DetailsSwiftUI Desktop App
Native macOS apps from the same SwiftUI codebase as your iPhone and iPad app.
DetailsTakeover and modernisation
After an audit we take over SwiftUI or UIKit projects or move older iOS apps to SwiftUI.

New Apple app, modernisation or a second opinion: describe your situation in three sentences and we name the sensible route.
Test our work on the App Store.
Chess Clock · Blitz Timer
Chess Clock is our own SwiftUI app: a chess clock with Fischer, Bronstein and delay increments, tournament time controls and Live Activities on the Lock Screen. One Swift codebase for iPhone, iPad, Mac, Apple Watch, Apple TV and Vision Pro, works offline, no account required, live on the App Store.
Byoyomi Timer · Go game clock
Our second SwiftUI app: a game clock for Go with Japanese byo-yomi, Canadian overtime, Fischer bonus and more time systems, voice countdown in multiple languages and Live Activities on the Lock Screen. For iPhone and iPad, works fully offline, no account required.
Frequently asked questions about our SwiftUI agency.
Can't I just build a SwiftUI app myself with AI?
For a prototype, yes. For an app that passes Apple's review and stays maintainable, rarely. AI produces Swift code but no architecture and no store compliance. We work AI-assisted ourselves, backed by our own SwiftUI apps on the App Store.
How much does a SwiftUI app cost?
The feature scope sets the range, from a focused MVP to an app with a backend, iCloud sync and Watch extension. After the first call you get an itemised, non-binding estimate.
How long does SwiftUI app development take?
An MVP for iPhone is often testable via TestFlight within a few weeks. An app with a backend, Watch extension and store launch takes longer. The concept fixes the timeline with milestones.
Does a SwiftUI app also run on Android?
No, SwiftUI runs on Apple platforms only. For iOS and Android from one codebase we recommend Flutter or React Native. For native iOS app development aimed at iPhone, iPad and Mac, SwiftUI plays to its strengths.
Do you take over existing iOS projects?
Yes. After a code audit we name the state and risks, then take on development and maintenance: pure SwiftUI, mixed with UIKit or an older Objective-C foundation.
Does SwiftUI cover Apple Watch and Vision Pro too?
Yes. The same Swift codebase yields watchOS, macOS and visionOS versions, adapted per device. We plan those stages in from the start.
