React Native Development in St Davids
Building with React Native for St Davids organisations, where the interface uses real platform components and the logic runs in JavaScript. That split is why apps feel native and why performance problems concentrate in specific places — long lists, animations and anything doing substantial work while the user is scrolling.
Why this comes up
The problem
Scrolling stutters on a long list, and the cause is work happening in JavaScript while the user is dragging.
What you get
What we deliver
- Lists built with virtualisation rather than rendering everything
- Animations driven natively so they continue smoothly under load
- Heavy computation moved off the path that runs during interaction
- Images sized and cached properly, as these dominate memory on device
- Platform differences handled where behaviour genuinely diverges
- Performance measured on a mid-range device rather than a recent flagship

React Native Development in St Davids — common questions
- Why do lists cause so much trouble?
- Because rendering everything is easy and expensive. A list of a thousand items built naively creates a thousand components, and virtualised rendering — keeping only what is near the viewport — is the difference between smooth scrolling and an app that stutters.
- What makes animations stutter?
- Driving them from JavaScript while it is busy. Animations that run natively continue smoothly regardless of what the logic thread is doing, which is why the same animation can be flawless in one screen and janky in another.
- Which device should we test on?
- A mid-range one a few years old, because that is what a large share of users have. Testing exclusively on recent hardware hides performance problems until reviews start mentioning them, by which point the fix is more expensive.
- Do we still write platform-specific code?
- Some, and less than with native development. Behaviour around permissions, notifications, back navigation and system dialogs genuinely differs, and handling those properly is what separates an app that feels native from one that clearly is not.
- Do you work with businesses across Pembrokeshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including St Davids and the surrounding Pembrokeshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of St Davids businesses do you usually work with?
- Simple booking and payment systems for very small hospitality and tourism operators on the Pembrokeshire coast. Beyond that we work across Tourism & Heritage, Hospitality, Agriculture, Marine and Retail.
- Do you cover the areas around St Davids?
- Yes — we work throughout Wales, including Swansea, Cardiff. St Davids is an urban area of roughly 1,600+, and we take on work across the wider Pembrokeshire region rather than the city boundary alone.
