Mobile App Development Services
Getting an app built is the easy half. Getting it through review, keeping it working without signal, and shipping updates without breaking anyone is the rest of it.
We build mobile products where the phone is the primary way people use the thing, not a companion to a website. That changes the engineering. Connectivity is not guaranteed, the update cycle is controlled by two companies who are not you, and a crash rate that would be tolerable on the web will get you uninstalled.
Most of our work is React Native with Expo, sharing a codebase across iOS and Android and dropping into native modules where it genuinely matters. We are not religious about it. When a feature needs native performance or a platform API the bridge handles badly, we write native.
Offline is a design constraint, not a feature
If your users are pilots, drivers, field engineers or market traders, they will be offline regularly and they will not accept a spinner as an answer.
Building for that means deciding early what the phone is allowed to be the source of truth for, how conflicts resolve when two devices edited the same record, and what the user sees while a sync is pending. Retrofitting offline support into an app that assumed connectivity is close to a rewrite, which is why we ask about it in the first conversation.
Store review is part of the schedule
App Store and Play Store review is not a formality and it is not predictable. We plan for it. Builds go through TestFlight and internal tracks early, so the first submission is not also the first time anyone has seen a release build.
Payments, subscriptions, account deletion, privacy labels and permission prompts are the usual rejection reasons. All of them are cheaper to handle correctly at build time than during a rejected release with a launch date already announced.
The backend is usually the real project
A mobile app is a client. Almost every mobile engagement we take on is really a backend and API project with a mobile client attached, and pricing it any other way sets everyone up for disappointment.
We build both sides, usually Laravel behind the app, which means the API is designed for the screens that exist rather than reverse engineered from a generic REST layer that fits nothing well.
Work we have actually shipped
Mobile work that is live in the stores or in daily field use.
Oxodin, a voice first agentic personal assistant for a Swiss AI company, live on both the App Store and Google Play. React Native and Expo on the client, Laravel and an agent layer behind it, with self hosted text to speech on Swiss infrastructure. We continue as the engineering team.
An aviation logbook used by thousands of pilots, six years in production. Offline first by necessity, because pilots log flights where there is no signal, then export regulator ready reports for EASA, FAA and CAA once they are back on the ground.
Cashless QR payments for traders, small businesses and corporate programmes across South Africa, pulling Apple Pay, Samsung Pay, SnapScan and Zapper into one wallet with next day settlement. We have been the embedded engineering partner since early 2026.
Questions we get asked
React Native or fully native?
React Native for most products, because one codebase across two platforms is a real cost saving and the performance ceiling is higher than its reputation suggests. Fully native when the app is graphics heavy, deeply tied to platform APIs, or when you already have native teams to maintain it.
Do you handle App Store and Play Store submission?
Yes, including the parts nobody enjoys: privacy labels, data safety forms, review responses and staged rollouts. We have shipped to both stores and would rather own that process than hand you a build and wish you luck.
Can you take over an existing app?
Usually. The honest answer depends on how the state management and API layer were built. We do a paid audit first and tell you plainly whether continuing or rewriting is cheaper, including when the answer is not the one that earns us more work.
How long does a first version take?
A focused first release is typically three to four months including backend, store submission and a real beta. Anything promising six weeks is either very small or is not counting review, payments and the offline path.
