App modernisation and rescue
Rescue, rebuild or improve an existing app. We audit ageing or unstable apps, fix what matters most and plan a path to a modern, maintainable codebase.
App Modernisation: what it is and why it matters
Apps age quickly. Operating systems change every year, libraries go out of date, original developers move on and small bugs accumulate into poor reviews. Eventually every new feature feels slow and risky.
App modernisation is a structured way to regain control. We start with an honest audit of the codebase, performance, security and user feedback, then fix what matters most and set out a path to a modern, maintainable product — rebuilding only where it genuinely makes sense.
We regularly take over apps from previous agencies or freelancers, and we document everything as we go so you are never dependent on a single person again.
How long does it take?
An audit takes two to three weeks. Stabilisation usually shows results within the first one to two months.
Signs it’s the right time
If any of these sound familiar, App Modernisation could quickly pay for itself.
Best suited to: Apps with poor reviews · Products left by a previous agency · Apps stuck on old frameworks
Your app has falling ratings or frequent crashes
Your previous developer is no longer available
Updates take longer and break other features
The app uses outdated frameworks or fails new store requirements
How we deliver App Modernisation
A clear, collaborative process with something tangible to review at every step.
Audit
Review code quality, architecture, dependencies, security, crash data and reviews.
Stabilise
Fix the most damaging crashes and bugs first, quickly improving the user experience.
Modernise
Upgrade frameworks, refresh the interface and refactor the riskiest parts of the code.
Sustain
Introduce tests, documentation and a regular release process.
Questions to ask before you hire
Whoever you choose for App Modernisation, these questions will help you compare suppliers.
Will they audit before quoting?
Fixed prices without an audit are guesses.
Do they recommend a rebuild by default?
Rewrites are expensive; incremental improvement is often better.
How will knowledge be documented?
Avoid repeating the single-developer problem.
How quickly can they stabilise things?
Look for early, visible wins.
Should we rebuild or improve our existing app?
It depends on the audit. If the foundations are sound, improving is faster and cheaper. If they are not, we will explain why a rebuild is worth it.
Can you work with code written by someone else?
Yes, taking over existing codebases is a regular part of our work.
Will users lose their data?
No. Data migration and backwards compatibility are planned carefully.
Can you convert a native app to Flutter?
Yes, where it makes sense we can migrate to a single cross-platform codebase.
Do we own the work?
Yes. You own the code, designs and content we create for you.
