Problems we solve

Why mobile projects go sideways

Most mobile projects struggle with duplicated effort across platforms, unclear API contracts, and release surprises. We plan for these from day one.

The problem

Two platforms, double the cost

We build with React Native and Expo so iOS and Android share one TypeScript codebase, while still using native capabilities such as camera, location and biometrics where needed.

The problem

Your web product has no mobile counterpart

We extend your existing platform with a mobile client and a dedicated, token-based API, without disturbing how the web app works.

The problem

Staff or customers need to work on shared devices

We design for real-world use, including personal mode and shared-kiosk mode, so one app can serve both phones and tablets.

The problem

App store releases feel risky

We set up development builds, internal testing tracks and store submission, and handle review feedback so launch day is predictable.

FAQ

Frequently asked questions

Do you build for both iOS and Android?

Yes. We use React Native with Expo, so one TypeScript codebase produces both iOS and Android apps while still using native features like the camera, location, notifications and biometrics.

Can the app connect to our existing web platform?

Yes. We build or extend a secure API for the app, usually token-based, so the mobile app and your web platform share the same data and business rules.

Do you publish the app to the App Store and Google Play?

We handle builds, internal testing, store listings and submission. You will need your own Apple Developer and Google Play accounts so the apps are published under your name.

Can one app work on shared tablets as well as personal phones?

Yes. We have built apps with a personal mode and a shared kiosk mode, for example staff clock-in on a restaurant tablet.

How long does a mobile app take?

A focused first version typically takes 8 to 14 weeks, depending on the number of screens, integrations and whether the backend already exists.

Who owns the code and intellectual property?

You do. Once invoices are paid, all source code, designs and documentation are yours. We work under a written contract and sign an NDA before discussing sensitive details.
