01
UX & UI design
User flows, prototypes and interfaces that follow iOS and Android conventions, built around the actions that matter.
✓ User flows & wireframes
✓ Clickable prototypes
✓ UI design for iOS & Android
✓ Component design system
Service 03
Apps that earn a place on the home screen.
iOS, Android and cross-platform apps, designed around what your users come back to do. We pick React Native, Flutter or native Swift and Kotlin to suit the product, and build the backend and admin behind it.

Trusted by teams across six industries
(01) What’s included
Four parts of an app that lasts.
Each part can be scoped on its own, but they work best planned together, so design, build and release agree from day one.
02
Development
The app and everything behind it, on the stack that suits the product.
✓ React Native or Flutter
✓ Native Swift & Kotlin
✓ Backend & API
✓ Admin panel
03
Release & upkeep
From the first store submission to the updates that keep the app working on every new OS.
✓ App Store & Google Play release
✓ Push notifications
✓ OS & security updates
✓ Maintenance retainer
04
Analytics & growth
Know what users do, catch crashes before reviews mention them and bring in installs that stay.
✓ Analytics & event tracking
✓ Crash reporting
✓ App store optimisation
✓ Install campaigns
(02) When to invest
Signs it’s time for an app.
If two or more sound familiar, an app will usually pay its way. If none do, a fast mobile website is often the better buy, and we’ll tell you so.
Talk it through →- 01Customers use you every week, not once a year.
- 02Your product needs the camera, location, offline use or push notifications.
- 03Customers keep asking whether you have an app.
- 04Your web app feels slow or clumsy on a phone.
- 05You need to test an idea with real users before you raise or hire.
- 06Your current app is buggy, out of date or stuck with a developer who has left.
(03) Process
How an app project runs.
One project lead takes you from research to release. You review and sign off at the end of every stage.
01
Research & scope
We look at your users, competitors and goals, then agree the features, platforms and a fixed scope before design starts.
Output: Scope & roadmap02
Design & prototype
The key flows designed for iOS and Android, then turned into a clickable prototype you can put in front of users.
Output: Prototype & UI03
Build & test
Development on the chosen stack, with the backend and admin built alongside and test builds on your own phone as features land.
Output: Test builds04
Release & maintain
We submit to the App Store and Google Play and answer reviewer questions, then keep the app current with OS updates, fixes and new features on a monthly retainer.
Output: Live app & retainer (04) Engagements
Three ways to work with us.
Every engagement is quoted at a fixed fee once the scope is agreed, so you know the build cost before we start. Upkeep after launch is a monthly retainer.
MVP
The core of your idea, built to test with real users or show investors.
✓ Scope workshop
✓ Core screens & flows
✓ Cross-platform build
✓ Test builds or store release
Full product
A complete app for iOS and Android, with the backend, admin panel and store release.
✓ Research & roadmap
✓ UX & UI design
✓ Backend, API & admin
✓ Store release & analytics
Rebuild or takeover
For an app that is buggy, out of date or left behind by its last developer.
✓ Code & store audit
✓ Fix & stabilise plan
✓ Migration or rebuild
✓ Ongoing maintenance
Whichever suits the product. React Native or Flutter when one codebase for iOS and Android makes sense, and native Swift and Kotlin when the app leans hard on the device or needs maximum performance. We recommend one during scoping.
Cross-platform is faster to build and cheaper to maintain for most apps. Native is worth it for heavy graphics, complex device features or when you need each platform’s newest features the day they ship.
An MVP takes about four weeks. A full product depends on the features, integrations and platforms, so we set the timeline after research and scoping.
Every project is quoted at a fixed fee once the scope is agreed. The price depends on the screens, platforms, backend work and integrations. Maintenance after launch is a monthly retainer.
Yes. Code repositories, App Store and Google Play developer accounts and backend hosting are set up in your name, and all rights transfer to you on final payment.
Yes. We start with an audit of the code, the backend and the store listings, then recommend fixing, migrating or rebuilding, and quote for it.
Yes. We prepare the listings, screenshots and privacy details, submit the builds and answer reviewer questions until the app is live.
