We build iOS and Android apps with React Native or native code, together with the AI features and APIs that make them useful, from in-app assistants to offline sync.
Problems we see often, and the systems we build to solve them.
Customers who need answers inside your app, not a phone queue.
We build in-app assistants that answer questions, look things up and take bookings, using your own systems and data. Our founders built the AI layer for a patient app with more than a million downloads.
Conversations recorded in the app that nobody has time to turn into notes.
We build transcription and summarisation pipelines that turn a recording into structured documents. In Doctor Notes, a medical-visit recorder app, one consultation recording becomes a transcript, summary, SOAP note and referral letter.
Field teams losing work when the signal drops.
We build offline-first apps that store data on the device and sync it when the connection returns.
Releases that stall in App Store or Google Play review, or ship without proper testing.
We build release pipelines with device testing, store compliance checks and staged rollouts.
The exact scope is agreed in discovery. Every build includes automated tests, deployment scripts and full access to the code.
A React Native app for iOS and Android, or native Swift and Kotlin where the use case needs it.
Assistants, transcription and search inside the app, with the APIs behind them.
On-device storage with background sync and conflict handling.
A clickable prototype, tested on real devices before the full build.
Camera, location, notifications and Bluetooth, where the product needs them.
Work our founders have delivered in previous roles, as independent engineers and for our own products, across AI, Salesforce and product engineering.
Digital health, Medical documentation
The AI pipeline behind a medical-visit recorder: one consultation recording becomes an accurate transcript, a plain-language visit summary, and clinician formats such as SOAP notes and referral letters.
Religious education, EdTech
A chatbot that answers questions about Islam from a curated library of religious texts, with signed-in users and conversation monitoring.
Crypto, DeFi, Web3 infrastructure
An open-source MCP server and agent layer that lets AI assistants carry out real crypto operations: wallet management, swaps, DCA and limit orders, and staking.
Four stages, with working software to review at every milestone.
We define the core journeys, the devices to support and what must keep working offline.
App and backend are built together in two-week milestones, with test builds on your own devices.
Testing on real iOS and Android devices and poor network conditions, plus store compliance checks.
We manage App Store and Google Play submission, certificates and staged releases.
Every project is priced from an agreed scope, milestone by milestone. These are the factors that determine its size:
Fixed-price milestones, working software to review every two weeks, a 30-day warranty after launch, and full ownership of your code and IP as milestones are paid.
Request a fixed-scope proposalWe decide based on your performance needs and budget. For most business apps, a cross-platform framework such as React Native gives near-native performance while sharing most of the code between iOS and Android. For specialised hardware or low-level graphics, we build natively in Swift and Kotlin.
We manage the release process: store listings, privacy disclosures, builds and certificates, and responses to review feedback.
If it needs to. We design an offline-first data layer so people can keep working, and their changes sync when the connection returns.
Mobile Apps is preselected, and you can change it. A senior engineer reviews every brief and replies within one business day.
