iPhone users delete clunky apps in seconds. We build the kind they keep.

We build iOS apps in Swift and SwiftUI that feel at home on iPhone and iPad, are ready for App Store review and stay fast as you add features.

## Problems we solve

- Our app feels slow and clunky next to competitors: Laggy scrolling and odd navigation make users give up.
- App Store review keeps rejecting us: Every rejection pushes the launch back another week.
- Our last developer disappeared mid-project: Half an app, no documentation and a launch date that has already passed.
- We can't see progress until it's too late: You only get a build when it's almost done, and it never quite is.

## What we build

- Native Swift and SwiftUI: Fast, smooth apps that follow Apple's design guidelines
- Apple platform features: HealthKit, ARKit, Core ML, widgets, App Clips and Apple Pay
- Payments and subscriptions: In-app purchases and subscriptions with StoreKit
- Offline and sync: Core Data and CloudKit so the app works without a connection

## How we work

- Design (2-3 weeks): We design screens and flows that follow Apple's patterns and test them as a clickable prototype.
- Develop (8-14 weeks): We build the app in Swift and SwiftUI in two-week sprints, with a TestFlight build for you every week.
- Launch (1-2 weeks): We prepare store listings, privacy labels and screenshots, submit the app and handle any review questions.
- Iterate (Ongoing): We track crashes and usage, fix issues quickly and ship improvements in regular updates.

## Results

- RSA Garage: Roadside assistance app that connects drivers to nearby garages and parts vendors. Built with React Native, Node.js, MongoDB and Google Maps.
- PreLoved Baby Essentials: Mobile marketplace for second-hand baby products with in-app payments. Built with React Native, Firebase and Stripe.
- Elite Quiz: Trivia app with AI opponents and AI-personalised question picks. Built with React Native and Socket.io for real-time play.

## Questions

### Native iOS or cross-platform?
If you need Android too and the app is mostly forms, lists and content, React Native or Flutter can save money. If you need top performance or deep Apple features like HealthKit or ARKit, native Swift is the better choice. We'll recommend one and explain why.

### What if App Store review rejects the app?
We check Apple's guidelines throughout the build, so most issues are caught before submission. If a rejection happens, we fix the issue and resubmit as part of the project.

### Who owns the app and the developer account?
You do. The app is published under your Apple Developer account, and you own 100% of the code. We sign an NDA before you share anything.

### What does an iOS app cost?
It depends on features and integrations. After a free 30-minute call, we send a written plan and a fixed price within 48 hours. Dedicated iOS developers start from $25/hour.
