Commerce apps
Catalogue, cart, payment and order tracking, sharing data with the online store you already operate.
Mobile App Development
Apps for iOS and Android from a single codebase, wired directly into the web platform you already run. We handle store submission and release management too.
Overview
One codebase, both operating systems
Building separate native apps for iOS and Android means paying twice up front and twice again for every fix afterwards. For most business applications a shared codebase covers the requirement at a fraction of the cost.
More important than the framework is whether the app talks properly to the systems you already operate. We design the data layer first, so what users see on the web and in the app is always the same information.
- One codebase for iOS and Android, lower maintenance cost
- Two-way data sync with your existing web platform
- Push notifications by segment or by user behaviour
- Submission, review and update handling on both stores

How does app cost compare with a website?
Apps generally cost more because they must be tested across many devices and pass App Store and Google Play review. On the other hand, if you already have a web platform the data layer is reused, which brings the figure down considerably.
Whose name is the developer account in?
Yours. We help register and configure it, but ownership of the account and the published app stays with your company, exactly as with the source code.
Can the app work offline?
Yes, where the use case needs it. Data is cached on the device and synchronised once connectivity returns — commonly required for field staff applications.
