One fix breaks another feature
Code and app state are spread across many areas, so a local change can have a wide effect.
Legacy code. Live product. Clear route forward.
Modern mobile. Without the rewrite.
We modernise older iOS and Android codebases one safe module at a time, using SwiftUI and Jetpack Compose without putting delivery on hold.
One module at a time. One release at a time.

// UIKit + callbacks final class FeedController: UIViewController { ... func loadFeed() { API.fetch { result in DispatchQueue.main.async { self.items = result self.table.reloadData() } } } ... }
// SwiftUI + observable state + @Observable final class FeedModel { var items: [FeedItem] = [] + func load() async throws { items = try await api.feed() } } + FeedView(model: model)

When simple changes feel too hard
The code is slowing down the product.
Older app code does not fail in just one way. You see bugs come back, data change at the wrong time and small jobs turn into risky releases.
App state changes at the wrong time
Two tasks update the same data, and no one part of the app clearly owns it.
Too many parts depend on each other
Features rely on shared services, so they are hard to test, replace or build on their own.
Small jobs take too much effort
A simple feature can need wide code changes, long tests and help from only a few key people.
These problems are linked. They show that the code no longer has clear, safe places to make a change.

The way forward
Lower the risk before you speed up.
We find the problems, prove a better pattern in the live app, then use it in more parts of the codebase.
See the whole system
We map the bugs, shared state, builds, tests and who owns each part.
Pick one useful part
One small module tests the new plan without putting the release at risk.
Release it to users
We use release controls and live data to see if the new part works.
Use the pattern again
We work with your engineers until the better way of building feels normal.
AI-directed delivery
AI accelerates the work. We remain accountable for what ships.
We carry out the refactoring for your team. Before implementation begins, we establish the architectural boundaries, coding standards, testing expectations and behaviours the application must preserve. AI then accelerates analysis and implementation under direct human oversight.

What we do
Native mobile skills for the whole release process.
We can improve one iOS or Android app, or plan both together. Every project can start with a clear review of the code and release process.
iOS / Apple
SwiftUI modernisation
Move UIKit, storyboards and callback code into clear Swift and SwiftUI features that are easier to test.
Explore iOS services →
Android / Google
Kotlin & Compose
Move Java and older Android screens into clear Kotlin code and Jetpack Compose.
Explore Android →
Both platforms
iOS and Android together
Share the plan, tests and release checks while keeping each app truly native.

A project example
From risky releases to a safer way to change the app.
A live marketplace app that could not stop.
The team still had features to ship. But the account area shared data with too many screens, bugs crossed into other features and only a few engineers knew how to release it safely. We split out the account journey, rebuilt it with native code and proved the new release path before moving deeper.
