App development
in Lincoln
I design and build custom mobile apps — native iOS with Swift, Android with Kotlin, and cross-platform with React Native. From first sketch to a polished product on the App Store and Google Play. Based in Lincoln, working with businesses across Lincolnshire and the UK.
Get in TouchWhat I offer
Everything you need,
nothing you don't.
Native iOS Development
Built with Swift and SwiftUI for the best possible experience on iPhone and iPad. Smooth animations, native feel, and full access to Apple's ecosystem — from HealthKit and CoreBluetooth to ARKit and Apple Pay.
Native Android Development
Kotlin and Jetpack Compose for clean, modern Android apps. Material Design, full Google Play Services integration, and support for the huge range of Android devices out there.
Cross-Platform Apps
React Native and Expo for apps that run on both iOS and Android from a single codebase. Perfect when you need to reach both platforms without doubling your budget.
Backend & API Development
Most apps need a server behind them. I build robust backend systems — user authentication, databases, push notifications, real-time sync — everything your app needs to work properly.
BLE & Hardware Integration
Experience with Bluetooth Low Energy, NFC, and IoT device communication. I rebuilt the eLOQ BLE access management system for Lincoln Security — real hardware, real production use.
App Store Submission & Maintenance
I handle the entire publishing process for both stores, including ongoing updates, bug fixes, and feature additions. Your app stays current and compliant.
Tech stack
How it works
A clear process,
start to finish.
Discovery & Scoping
I learn what your app needs to do, who it's for, and what platforms make sense. We agree on features, timeline, and budget before any code gets written.
Design & Prototyping
Wireframes and interactive prototypes so you can see and feel the app before development starts. Iteration is cheap at this stage — changes later cost real money.
Development & Testing
I build in sprints with regular demos. You see working software every couple of weeks, not a big reveal at the end. Thorough testing on real devices throughout.
Launch & Ongoing Support
I handle App Store and Google Play submission, then stick around for bug fixes, updates, and new features. Your app isn't done just because it launched.
“Aaron worked with us and assisted with the modernisation of our eLOQ iOS and Android apps. He re-engineered both apps, improving the UI and optimising performance. He worked closely with our software developer, showing outstanding dedication to the project with clear communication throughout and a real commitment to understanding our product and delivering results.”

FAQ
Common questions
How much does it cost to build a custom app in the UK?▾
Every app is different, so I price each project individually after a proper scoping conversation. I give honest, fixed quotes with no surprises — get in touch and I'll give you a realistic figure based on what you need.
Should I build native or cross-platform?▾
It depends on what your app needs to do. Native (Swift for iOS, Kotlin for Android) gives the best performance and access to platform-specific features like Bluetooth, NFC, and advanced animations. Cross-platform with React Native is brilliant for apps that don't need deep hardware access and where budget matters. I'll recommend the right approach for your project — not the one that's easiest for me.
Do you publish apps to the App Store and Google Play?▾
Yes. I handle the entire process — from development and testing through to App Store and Google Play submission, including all the screenshots, descriptions, and review guidelines. I also manage updates and ongoing maintenance after launch.
Do I own the code?▾
Absolutely. Every line of code is yours. I hand over the full source code, documentation, and everything else you need. No lock-in, no licensing fees. It's your app.
