Mobile apps
for iOS and Android
One app, two stores. With React Native we build native-feeling apps from a single codebase — faster than running two separate teams.
I want a mobile appA mobile app does not have to be built twice, once for each platform. Using React Native and Expo, we create apps that look and feel native but ship significantly faster. From UX design and development through to App Store and Google Play release, we handle it all. We show you progress along the way and gather your feedback.
A mobile project rarely starts with the phone. It starts with data that sits in a CRM, a warehouse or an order system and needs to reach people who are not at a desk. So the first questions are where the app reads its data from and what it has to keep doing with no signal. iOS versus Android comes later.
When a mobile app is worth building
A responsive website covers most of what you want until you need the camera, location, code scanning or work with no signal. Three cases dominate: an app for field technicians recording work at the customer site; an ordering app for end customers; and a mobile layer over an internal system people reach through a browser today. The deciding question is whether anyone opens it more than once. Nobody installs a company brochure on their phone.
What we deliver
Cross-platform development (iOS + Android)
One codebase for both platforms. A new feature lands on iOS and Android at the same time.
Native performance and user experience
Lists scroll smoothly and screens respond without lag. Gestures and keyboards behave the way each platform expects.
Push notifications and offline mode
Messages arrive with the app closed. Data captured with no signal syncs once the device is back online.
Backend and API integration
The app reads from and writes to the systems you already run: CRM, warehouse, online store or accounting.
App Store and Google Play release
We prepare the listings and screenshots, and handle review and release on your behalf.
How we work together
- Scope and prototype We go through what the app must do and sketch the key screens. You see the scope in a prototype, not in code.
- Screen design Screens are designed for iOS and Android together and checked on real devices, not only in a design tool.
- Development and test builds Builds reach your phone as we go, through TestFlight or internal distribution, so a usable version exists long before release.
- Connecting your systems We wire the app into your CRM, warehouse or orders, verifying up front what can be read and written.
- Release and later versions We publish in both stores. Early reactions from users often turn into small adjustments right after launch.
Tech Stack
We choose React Native and Expo because small fixes can go out without waiting for store review. TypeScript catches most mistakes before a build ever reaches a phone, and Firebase covers notifications and sign-in so we are not maintaining that infrastructure ourselves.

PortfolioFrequently asked questions
We are based abroad. How do we follow what the team is building?
You install the app. Test builds reach your phone from early on through TestFlight or internal distribution, so progress is something you hold rather than read about. Tasks sit in your own tracker, and everything written down is in English.
How much of the working day do we actually overlap?
Our working day starts before the London morning and ends around lunchtime on the US East Coast. That is a full overlap with continental Europe and all but an hour of the UK day. Release days are worth scheduling inside that overlap; the rest of the work runs asynchronously.
We need a mobile app connected to our CRM. Is that something you do?
Yes, it is a common brief. What matters is whether your CRM has an API and how fast it answers, because a phone is often on a slow network. Without an API we can work from database access or an export, but it is slower.
When is React Native not the right choice?
With demanding graphics and deep hardware work: games, heavy video processing, or Bluetooth peripherals running their own protocol. We say so at the start. Finding it out halfway through a project means rewriting work that is already done.
Is the app enough, or do we also need something on the server?
A server side is almost always needed. A phone does not connect straight into a company database; a middle layer serves the data, authenticates users and enforces permissions. If you already have that layer, we use it rather than build another.
Will the app work without a signal and send notifications?
Yes, but offline has to be designed in from the start. The real questions are which data is stored on the device and what happens when two people edit the same record. We keep notifications targeted; blanket announcements get switched off.
What happens after the app is released?
It needs maintenance even when no features are added. Apple and Google keep raising their minimum requirements, and an app that ignores them eventually leaves the store. We publish under your own developer account, watch crashes and new OS versions, and flag changes in advance.
