Mobile App Development for iOS and Android
We build cross-platform mobile apps that reach the stores and keep working afterwards — marketplaces, booking platforms and consumer products, with the backend, the infrastructure and the release process handled by the same team that wrote the app.
What we build
Most of our mobile work is React Native with Expo, sharing one codebase across iOS and Android. That is a deliberate choice rather than a default: for the products we build — marketplaces, booking flows, content feeds — a shared codebase halves the cost of every feature and keeps the two platforms from drifting apart. Where a product genuinely needs platform-specific behaviour, we drop into native modules for that piece alone.
Every app we ship talks to a backend we also build, normally NestJS with PostgreSQL. Having the API and the client in one team removes the most common source of delay on mobile projects: waiting for someone else to change an endpoint.
Typically included
- iOS and Android from a single React Native codebase
- Authentication, including Google and Apple sign-in
- Payments — Stripe, or per-country providers where needed
- Push notifications and background jobs
- App Store and Play Store submission, including review responses
- Crash and error reporting wired in before launch
Multi-language and RTL, not as an afterthought
Every mobile product we have shipped supports English, French and Arabic. Arabic matters more than it sounds: it means right-to-left, and RTL is not translation. Layouts mirror, icons flip, text runs bidirectionally where Latin names appear in Arabic sentences, and dates and numbers format differently.
Retrofitting RTL into an app that was not designed for it is expensive and usually looks wrong. We build it in from the first screen, which costs very little at the start and is close to impossible to add cheaply later. If your market includes the Gulf or North Africa, this is the difference between an app that works there and one that merely runs there.
AI features where they earn their place
We integrate AI into mobile products when it removes real work for the user — generating a listing from a photo and a few words, drafting an itinerary, parsing a confirmation email into structured data, suggesting a reply. We are equally willing to tell you where AI adds cost and no value, which is a large part of what a discovery sprint is for.
These are ordinary product features that happen to call a model, so they are subject to the same standards as everything else: they need to fail gracefully, cost a predictable amount per user, and work when the model is slow or unavailable.
Common questions
How long does a mobile app take to build?
A focused first version — one platform, a defined set of screens, a real backend — is typically four to ten weeks depending on scope. We start with a one-week discovery sprint that produces a costed plan, so you get a real timeline before committing to the build.
React Native or fully native?
React Native for most products, because one codebase across iOS and Android roughly halves the cost of every subsequent feature. Fully native is the right call when the product depends on heavy device APIs, sustained background processing, or platform-specific hardware. We will say which applies to you during discovery.
Do you handle App Store and Play Store submission?
Yes, including the review process and any rejections. Store review is a normal part of delivery, not an extra.
Can you take over an existing app?
Often, yes. We start by reading the codebase and giving you an honest assessment — including telling you if a rewrite would cost less than continuing, which is sometimes the answer.
